Above 30 degrees paint temperature the cleaner flashes off before the dwell time is up — leaving dull streaks that only come off with polish. Before you start, move the vehicle into the shade or rinse it down with cold water first. In full summer sun, reach for the milder Pre-Foam efficient instead, which is far more forgiving with its 1-minute maximum dwell time.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:30 for insects. 1:300 for high pressure.\u003c\/h3\u003e\n\u003cp\u003eDilution depends on how dirty the vehicle is and how you apply it. 1:30 to 1:50 for the pre-wash, 1:3 to 1:10 for heavily soiled wheels, 1:300 for self-service high-pressure units.\u003c\/p\u003e\n\u003cp\u003eFor the touchless pre-wash with a foam lance you work at 1:30 to 1:50. One litre of concentrate at 1:50 gives you 51 litres of ready-to-use solution — enough for roughly 20 to 25 cars in standard exterior care.\u003c\/p\u003e\n\u003cp\u003eThe foam lance should run at 0.8 to 1.2 litres per minute flow so the foam consistency is right and the cleaner clings to vertical panels long enough to do its job. Apply the pre-cleaner from the bottom up onto the cold, pre-wetted vehicle — that way you avoid run marks on unevenly dried panels. After 5 minutes dwell time at most (VDA Class A), rinse off thoroughly with the pressure washer.\u003c\/p\u003e\n\u003cp\u003eIn self-service wash bays, 1:300 is enough — that's the high-volume dilution and it cuts product use noticeably over a full year. For wheel cleaning you work at 1:3 to 1:10, sprayed straight onto the cold dry wheel, left to dwell for 1 minute at most, then rinsed. Important: don't use it on hot brake discs or warm wheels. The heat speeds up the reaction in an uncontrolled way and raises the risk of dulling on painted alloy wheels.\u003c\/p\u003e\n\u003cp\u003eFor wash tunnels with conveyor lines you typically run 1:100 to 1:200. Dwell time in the tunnel is usually 30 to 60 seconds, which still keeps you safely inside the VDA-B limit of 1 minute. The higher dilution cuts foam volume at the spray arch but keeps enough cleaning power thanks to the high active-ingredient concentration. With high vehicle throughput it pays to switch to the 225 kg container — a better price per litre of concentrate.\u003c\/p\u003e\n\u003cp\u003eFor copolymer de-waxing — stripping old preservatives before a fresh sealant — 1:5 to 1:10 is the right dilution.

No snow foam replacement.\u003c\/h3\u003e\n\u003cp\u003eThe Koch Chemie Vorreiniger B is not a mild foam pre-cleaner for coating-protected vehicles. pH 13.1 is workshop level — strong, uncompromising, but sensitive in use.\u003c\/p\u003e\n\u003cp\u003eIts strength is on heavily soiled vehicles with insect, bird-dropping and road residue after a long motorway run or after winter. It also works reliably on baked-on brake dust on steel wheels and on alkali-resistant painted alloy wheels. The foam is functional — not the show foam you get from classic snow-foam products, but a working foam that clings to vertical panels.\u003c\/p\u003e\n\u003cp\u003eNow the honest read on the limits. First, the Vorreiniger B is not friendly to active ceramic coatings. Used regularly on coating-protected vehicles it breaks the coating down faster than a pH-neutral pre-wash foam does. For vehicles with an active coating, the milder Pre-Foam efficient is the better call. Second, don't use it on polished aluminium or chrome surfaces — despite the corrosion inhibitors, pH 13.1 can dull untreated light metals. The inhibitors protect anodised alloy, not bare alloy.\u003c\/p\u003e\n\u003cp\u003eThird: it is not paint-surface gentle in the sense of a hand-wash chemistry. If you look after your new car with the two-bucket method and a mild car shampoo, you don't need a Vorreiniger B in the garage. Its job starts where hand washing no longer cuts it — on heavily soiled vehicles, commercial fleets, utility vehicles and construction machinery.\u003c\/p\u003e\n\u003cp\u003eProtective gear is a must, not optional. Nitrile gloves and safety glasses when mixing and applying. On skin contact, rinse straight away with plenty of water and remove residue with mild soap. Never leave the concentrate bottle open — the fumes from the alkaline cleaner irritate airways and mucous membranes on longer exposure. Close it well after use and store it frost-free and dark.\u003c\/p\u003e\n\u003cp\u003eThe material compatibility of the Vorreiniger B has clear limits. Allowed: steel, anodised aluminium, alkali-resistant painted surfaces, glass and standard automotive plastics. Not allowed: polished light metals, bare chrome surfaces, coloured anodised layers (risk of discolouration) and matt-painted surfaces without a protective film.

If you supply express wash lines with extremely short dwell times, reach for the Pre-Wash B.

Let the cleaner dwell for 2–5 minutes without letting it dry on — in hot weather or direct sun, shorten the dwell time and keep the car damp. Then rinse thoroughly with the pressure washer before you go into the shampoo pass. For maximum bug removal, run the cleaner stronger across the front end (grille, bumper) and, if needed, work it briefly with a soft brush before you rinse.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eAlkaline car pre-cleaner — how the MultiClean Alkaline works chemically\u003c\/h3\u003e\n\u003cp\u003eMost of the organic dirt on a car — bug splatter, pollen, bird droppings, the fatty salts off road wear, oil film — is stable in the acidic-to-neutral pH range. A high-alkaline cleaner like the \u003cstrong\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/strong\u003e shifts the chemical balance: esters and fatty compounds in organic grime are split apart by saponification under alkaline conditions, protein structures in bug residue are denatured and dissolved. The result isn't a mechanical lift-off but a chemical destabilisation of the dirt — the bond to the paint is weakened without you having to work the surface mechanically.\u003c\/p\u003e\n\u003cp\u003eOne thing to get right: high-alkaline pre-cleaners aren't \"do-it-all\" cleaners for every situation. They're tuned for organic, alkali-soluble grime. Mineral deposits like lime spots, water spots or embedded metal rust (brake dust as iron particles) barely react to an alkaline attack — that calls for acidic specialist cleaners. The MultiClean Alkaline makes sense in a two-wash concept: alkaline pre-wash first (organic grime), then a follow-up with an iron remover or acidic cleaner (mineral deposits). Combine both steps and you clean chemically all the way, instead of just looking clean.\u003c\/p\u003e\n\u003cp\u003eAlso important: alkaline pre-cleaners have to be rinsed off completely before you go into the shampoo wash — residue can react with some sealants or wax layers and knock back their bond for a while. A thorough pressure rinse after the dwell time is enough to clear the cleaner off fully. On freshly sealed cars (ceramic coating, paint sealant), only use it on genuinely heavily soiled spots and keep it out of the regular weekly wash, so you don't put unnecessary strain on the protection. For the routine wash of a sealed car, reach for a mild, pH-neutral shampoo as your standard wash product instead.\u003c\/p\u003e\n\n\u003ch3\u003eUsing a pre-wash like a pro — the application step by step\u003c\/h3\u003e\n\u003cp\u003eThe best way to use the \u003cstrong\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/strong\u003e starts on a dry car. Moisture on the paint thins the cleaner straight away and cuts the working concentration before it ever had a chance to act. Recommended method: fill the cleaner neat or at a low dilution ratio (1:3 to 1:10 depending on how dirty it is) into a pump sprayer, a \u003ca href=\"\/en\/products\/sonax-profiline-foamsprayer-schaumspruher\"\u003eSONAX PROFILINE FoamSprayer\u003c\/a\u003e or a foam cannon on the pressure washer, and spray it evenly across the whole car — bottom to top, so the cleaner runs down the bodywork and the lower, dirtier areas get properly wetted too.\u003c\/p\u003e\n\u003cp\u003eStick to the dwell time: 2–5 minutes is enough for typical road grime. Don't let it dry on — in direct sun or high temperatures, mist the car lightly in between or shorten the dwell time accordingly. After the dwell, rinse thoroughly with the pressure washer, then move into the normal shampoo wash. Alternatively, the MultiClean Alkaline can be run as a foam cleaner in the foam cannon — foam clings to the surface longer and stretches the effective dwell time with no extra effort. For really stubborn bug splatter on the front end, it pays to work a soft bug sponge or microfibre mitt over it after the pre-wash before you rinse — even that is already a lot gentler than going straight into a contact wash with no chemical pre-wash first.\u003c\/p\u003e\n\n\u003ch3\u003eBug remover for pros — when the alkaline pre-cleaner really shines\u003c\/h3\u003e\n\u003cp\u003eThe MultiClean Alkaline shows its strengths above all in the summer season, when bugs turn into a real cleaning problem. Bug residue is made of proteins, acids (formic acid, acetic acid) and fatty substances — a chemically complex mix that \"bakes\" into the paint the moment it sits for more than a few hours. Those acids in particular can damage paint if bugs aren't removed promptly in hot weather. The high-alkaline formula neutralises those acids and breaks down the protein structures at the same time — which makes the pre-cleaner an effective tool against bugs that cuts the mechanical load during the wash down to a minimum.\u003c\/p\u003e\n\u003cp\u003eA simple rule of thumb applies: the fresher the bug residue, the less dwell time the cleaner needs. Fresh splatter dissolves almost completely within 2–3 minutes of dwell time and then rinses off touchless. With older, dried-on residue — what you see day-to-day on cars left unwashed for several days after a motorway run — a second pass or a quick mechanical follow-up with a soft bug sponge may be needed. That's not a weakness of the cleaner, it's chemical reality: proteins that have been \"baked\" by heat and UV over days need more time or mechanical help to dissolve fully.\u003c\/p\u003e\n\u003cp\u003eBeyond the car body, it's especially worthwhile on motorhomes, vans and commercial vehicles: thanks to their size and mileage, these often carry many times the dirt load of a normal car, and the option of a touchless pre-wash saves a lot of time and effort here. Professional detailing operations run the pre-cleaner as a fixed part of their wash routine — as the first step, before pressure or foam come in. That doesn't just lift cleaning quality, it also stretches the lifespan of the wash pads and mitts, because they meet far less coarse grime.\u003c\/p\u003e\n\n\n\u003ch3\u003ePre-cleaners compared — MultiClean Alkaline vs. MultiStar and MultiClean Acid\u003c\/h3\u003e\n\u003cp\u003eThe SONAX PROFILINE range has three cleaners that look similar at first glance but are built for different jobs.

In pro work with daily use, the 5-litre container clearly pays off, since the price per litre comes out lower and the bigger canister gives you enough volume for larger vehicles and fleets too.\u003c\/p\u003e\n\u003cp\u003eWho gets the most out of this pre-cleaner? Professional detailers running a structured multi-step method (touchless pre-clean + foam wash + hand wash) who put paint safety first. Hobby detailers looking for an effective answer to stubborn traffic film after long runs or in bug season, without having to reach for aggressive chemistry. Owners of dark or sensitive paint, where wash marring shows up the most and the mechanical cleaning load should be kept to a minimum. And anyone who wants to dial in their wash process: pre-wash consistently and you spare the car, the wash gear, and your time in the long run.\u003c\/p\u003e\n\u003cp\u003eAs a practical workflow for your next wash: park the car in the shade, lay the MultiClean Alkaline down with a foam sprayer or foam cannon, let it dwell for 3–4 minutes, rinse thoroughly with pressure.

The \u003cstrong\u003eSONAX PROFILINE MultiClean Acid\u003c\/strong\u003e is the highly concentrated acidic heavy-duty cleaner in the PROFILINE system: built to cut through lime- and mineral-based soiling on wheels, vehicle surfaces, underbodies and hard industrial surfaces.

On painted surfaces, keep the dwell time short and rinse off with plenty of water — acidic cleaners attack clear coat and delicate surfaces if you let them sit too long. Protective gear (gloves, safety glasses) is a must when handling acidic concentrates. As the systemic counterpart we'd point you to the \u003ca href=\"\/en\/products\/sonax-profiline-multiclean-alkaline-vorreiniger\"\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/a\u003e for grease- and dirt-based soiling — together the two heavy-duty cleaners cover the whole pH spectrum of professional vehicle cleaning.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eAcidic chemistry in a heavy-duty cleaner — how the MultiClean Acid dissolves mineral soiling\u003c\/h3\u003e\n\u003cp\u003eThe way the acidic heavy-duty cleaner works comes down to an acid-base reaction: mineral deposits like calcium carbonate (limescale) and iron oxides (rust) are chemically alkaline or metallic. An acidic cleaner donates protons and converts these compounds into their ion form — calcium carbonate becomes calcium ions (Ca²⁺) and carbon dioxide (CO₂), iron oxides become soluble iron ions. That's the exact opposite of the original chemical bond, and it makes the deposits water-soluble and rinsable without any mechanical force.\u003c\/p\u003e\n\u003cp\u003eThe acid strength in the concentrate is set so it's effective enough to fully dissolve typical lime and rust deposits within manageable dwell times — while controlled dilution keeps it safe to use on more delicate surfaces. That makes the MultiClean Acid more versatile than specialist single products formulated for one specific soiling type and one specific surface. Thanks to that versatility and dilutability, the concentrate offers very good value for money in pro use.\u003c\/p\u003e\n\u003cp\u003eAn important chemical point with acidic cleaners is material compatibility. Acid-resistant materials like stainless steel, ceramic, glass and many plastics are fully compatible with acidic cleaners. Aluminium and certain light-alloy metals, on the other hand, are sensitive — acids can attack aluminium and leave it permanently dull or create an oxidative film. Painted surfaces tolerate short dwell times and a thorough rinse, but long dwell times or high concentration can cause clear-coat damage. Sticking to the recommended dwell times and dilutions isn't optional here — it's a core part of safe use.\u003c\/p\u003e\n\n\u003ch3\u003eUsing the MultiClean Acid right — dilution, dwell time and workflow\u003c\/h3\u003e\n\u003cp\u003eUsing the acidic heavy-duty cleaner takes a precise approach and a dilution rate matched to the soiling level and the surface. For light lime marks and regular wheel cleaning, go with 1:10 to 1:20 (1 part concentrate to 10–20 parts water). For medium soiling like cement haze or heavier limescale on tiles and hard surfaces, 1:5 to 1:10. For heavy deposits like long-dried rust or massive limescale, you may need 1:2 to 1:5 or neat use — take extra care here and keep it off delicate materials.\u003c\/p\u003e\n\u003cp\u003eWorkflow: wet the surface first with water to open up the substrate and slow the cleaner running off. Lay the diluted MultiClean Acid on generously — spray it straight onto horizontal surfaces, apply it to vertical ones with a sponge or brush. Dwell time 1–5 minutes depending on the soiling level and dilution rate — a visible foaming or fizzing reaction during dwell is a sign the acid is reacting with the mineral deposits and dissolving them. After the dwell, rinse thoroughly with plenty of water — get every bit of rinse water and acidic residue off, especially on metal surfaces that can corrode from acid residue.\u003c\/p\u003e\n\u003cp\u003eAfter cleaning with the acidic heavy-duty cleaner, it's worth doing a follow-up rinse with a neutral or slightly alkaline solution to fully neutralise any acid residue — especially on wheels and metal surfaces you'll be sealing or protecting afterwards. On freshly cleaned wheels, the \u003ca href=\"\/en\/products\/sonax-profiline-ceramiccoating-cc-rim-felgenversiegelung\"\u003eSONAX PROFILINE CeramicCoating \"CC\" Rim\u003c\/a\u003e makes a lasting layer of protection that seriously slows down future lime and brake-dust build-up and makes the next clean easier.\u003c\/p\u003e\n\n\u003ch3\u003eWhere to use it — typical soiling and surfaces for the acidic heavy-duty cleaner\u003c\/h3\u003e\n\u003cp\u003eThe acidic pro cleaner covers a broad range of jobs where mineral or acid-soluble soiling is the main issue. Wheel cleaning is one of the most common: brake dust has no direct affinity for acidic cleaners, but limescale from wash water and mineral films on wheel surfaces come off nicely with the acidic heavy-duty cleaner. On steel and stainless wheels it's no problem — on aluminium wheels, which are more acid-sensitive, bump up the dilution and shorten the dwell time.\u003c\/p\u003e\n\u003cp\u003eCement haze on vehicles and glass is a common headache on cars used near building sites or roadworks. The hard white film of cement dust that settles on paint and glass is alkaline and comes off nicely with the acidic heavy-duty cleaner — on glass (e.g. the windscreen) it's no problem with plenty of rinse water and leaves a clear, clean pane. Mineral water spots and lime rings from well water or hard wash water are another classic job — here the MultiClean Acid is the more heavily concentrated pro tool next to the \u003ca href=\"\/en\/products\/sonax-profiline-waterspot-remover-wasserfleckenentferner-kalkentferner\"\u003eSONAX PROFILINE Waterspot Remover\u003c\/a\u003e, which is built for single-detail care.\u003c\/p\u003e\n\u003cp\u003eFor underbody cleaning, the acidic heavy-duty cleaner works well against lime and mineral deposits that settle in the underbody — though here it makes sense to pair it with an alkaline pre-cleaner for grease- and oil-based soiling before you bring in the acid for the mineral bits. Shop floors, lifts and sanitary fixtures in detailing businesses where lime and mineral films build up can also be cleaned effectively with the diluted cleaner — a cost-effective double use for the large 5-litre container.\u003c\/p\u003e\n\n\u003ch3\u003eAcidic vs. alkaline heavy-duty cleaner — the right pick for every soiling type\u003c\/h3\u003e\n\u003cp\u003eThe SONAX PROFILINE MultiClean system is made up of two complementary heavy-duty cleaners that together cover the whole spectrum of professional vehicle and surface cleaning. The \u003ca href=\"\/en\/products\/sonax-profiline-multiclean-alkaline-vorreiniger\"\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/a\u003e is the alkaline pre-cleaner for grease-, oil- and dirt-based soiling — road film, bugs, tar, tyre rubber and organic residue come off nicely with the alkaline formula. The MultiClean Acid, on the other hand, is built for the complementary job: mineral, limey and rust-based deposits that don't react to alkaline cleaners.\u003c\/p\u003e\n\u003cp\u003eRule of thumb: alkaline cleaner first (road film, grease, organic dirt), acidic cleaner in the second pass (lime, rust, mineral films). Day-to-day, a lot of vehicle soiling is a mix — a grimy wheel carries brake dust (metallic\/oxide) as well as road film (organic) and lime films (mineral). You get the best clean by running both cleaners in sequence: Alkaline for the first coarse dirt, Acid for the leftover mineral residue.\u003c\/p\u003e\n\u003cp\u003eAgainst specialist single products like wheel cleaners or descalers, the MultiClean concentrates give you the economic edge of flexibility: one product, adjustable by dilution, for many cleaning intensities and surfaces. For detailing businesses with a mix of customer vehicles and shifting soiling profiles, the systematic MultiClean duo is more cost-effective than a pile of specific single products — and it seriously cuts down on storage hassle too.\u003c\/p\u003e\n\n\u003ch3\u003eBuying the SONAX PROFILINE MultiClean Acid — container size and use calculation\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eSONAX PROFILINE MultiClean Acid\u003c\/strong\u003e comes only in the 5-litre container, which puts it firmly in pro territory: the container size and concentrate format are built for continuous professional use, not the occasional private job. At a 1:10 dilution, 5 litres of concentrate make 50 litres of ready-to-use cleaner — enough for many hundreds of wheel cleans or dozens of full vehicle preps with lime removal. Even at 1:5 dilutions for heavier soiling, the container lasts for a great many cleaning jobs.\u003c\/p\u003e\n\u003cp\u003eFor professional detailing businesses cleaning several vehicles a day and running into mineral soiling regularly, the 5-litre concentrate is the most cost-effective buy. The price per litre of ready-to-use cleaner sits well below the market price for pre-diluted cleaners in consumer containers, depending on the dilution. The investment in the concentrate typically pays for itself within a few weeks of regular use against buying single ready-mixed cleaners.\u003c\/p\u003e\n\u003cp\u003eAs a systematic addition we'd point you to pairing it with the SONAX PROFILINE MultiClean Alkaline — together the two products form the complete cleaning system for every soiling type you run into in professional vehicle prep. Detailing businesses that use the MultiClean duo as a fixed cleaning system get a standardised approach that adapts to every vehicle type and soiling profile and delivers repeatable, solid results.\u003c\/p\u003e\n\u003cp\u003eImportant for businesses using the concentrate regularly: store the product cool and dry, keep it out of direct sunlight and away from frost. Close the container well after use to stop concentration changes from evaporation. In pro use it's worth prepping daily amounts in separate containers — that way you always work with freshly diluted cleaner, which keeps cleaning performance consistent. With these simple handling rules, the 5-litre concentrate is a lastingly cost-effective and effective part of the professional cleaning line-up.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"5 liters","offer_id":53622546366799,"sku":"D1-SNX-6325000","price":49.89,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/sonax-profiline-multiclean-acid-kraftreiniger-sauer_5-liter.png?v=1731053714"},{"product_id":"innovacar-sp1-prewash-vorwaesche-autoshampoo","title":"\"SP1\" Prewash Pre-Wash Car Shampoo","description":"\u003ch2\u003e\u003cstrong\u003eINNOVACAR \"SP1\" Prewash — Effective pre-wash for your car\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eINNOVACAR \"SP1\" Prewash\u003c\/strong\u003e is a high-grade pre-wash shampoo built to pull dirt, grease and road grime off the paint before you ever touch it with a wash mitt.

The colour change from clear to purple shows you in real time where iron contamination sits and how heavy it is.

That's not a fault, it's the normal state: brake dust, rail fallout and industrial emissions leave microscopic iron particles on every car.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003epH 6 and a gel formula for longer contact time.\u003c\/strong\u003e Most iron removers are thin and run straight off vertical panels. Q²M Iron stays put as a gel on the surface, which stretches the effective contact time. The near-neutral pH of 6 makes it safe for clearcoat, ceramic coatings, wheels of every type and glass — as long as you keep the dwell time to 2 minutes max.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eA must-do step before polishing and coating.\u003c\/strong\u003e Iron particles sit in the clearcoat, not on the clearcoat. Polishing only shifts them around, it doesn't pull them out. Q²M Iron dissolves the particles chemically out of the paint surface before you polish or lay down a coating. Skip this step and you seal the contamination under the coating — with the risk of long-term clearcoat damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e GYEON quotes a maximum dwell time of 2 minutes — much shorter than a lot of competitors. Stick to it. The active ingredient hits its saturation point after 2 minutes: leaving it on longer adds no cleaning power, but it does raise the risk of residue on the surface. With heavy contamination, a second pass always beats a longer dwell on the first. Always apply it to washed, wet paint — never on dry or hot surfaces, never in direct sun.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray on. 2 minutes. Rinse off.\u003c\/h3\u003e\n\u003cp\u003eGYEON Q²M Iron goes onto wet paint after the pre-wash and reacts visibly with the iron particles on the surface within 30–60 seconds. You'll need about 150 ml per car with medium contamination — that's three to four full car cleans from the 500 ml bottle.\u003c\/p\u003e\n\n\u003cp\u003eWork top to bottom: roof, bonnet, sides, then bumpers and sills. The lower areas are more contaminated because they catch the brake dust off the front axle head-on. Once the colour shift to purple kicks in, the reaction has started. After 2 minutes max, rinse off with a strong jet of water — don't wait any longer.\u003c\/p\u003e\n\n\u003cp\u003eFor the gaps between wheel spokes and hard-to-reach spots on the sill you can spread the product with a soft brush. Don't scrub — just spread it. The chemical reaction does the work. On new cars delivered by rail, count on two passes: the iron contamination from rail fallout is far heavier than from normal road use.\u003c\/p\u003e\n\n\u003cp\u003eOne detail GYEON doesn't spell out: Q²M Iron must not be diluted with water. The reason is simple — tap water holds trace amounts of iron, and the active ingredient would react with those traces straight away instead of working on the paint surface. That's also why the advice is to work on wet paint: the water already on the panel doesn't dilute the product, it helps you spread it evenly.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/gyeon-q2m-iron-anwendung-farbumschlag.jpg?v=1776067914\" alt=\"GYEON Q²M Iron in use with a purple colour change on black paint\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eQ²M Iron dissolves fallout. Not tar.\u003c\/h3\u003e\n\u003cp\u003eQ²M Iron reacts only with iron compounds — brake dust, rail fallout, industrial emissions. Organic grime like tar, tree sap, bug splatter or bird droppings shows no colour change and won't dissolve. That's not a shortcoming, it's chemistry: thioglycolic acid binds iron, not carbon.\u003c\/p\u003e\n\n\u003cp\u003eThe colour change is more than an optical effect here — it's a diagnostic tool. Heavy purple means high iron contamination. If a spot stays clear, there's no fallout there but possibly tar or organic dirt. That tells you how to pick your next cleaning step: where Q²M Iron doesn't react, you need a solvent-based \u003ca href=\"\/en\/products\/gyeon-q2m-tar-redefined-harzentferner-teerentferner\"\u003etar remover\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eSo for a full chemical decontamination you need two products: Q²M Iron for the inorganic contamination (iron) and a tar remover for the organic kind (tar, resin, adhesive residue). The order doesn't really matter — both products work on different types of grime and don't interfere with each other. After that comes the mechanical decontamination with a \u003ca href=\"\/en\/products\/gyeon-q2m-claylube-redefined-gleitmittel-reinigungsknete\"\u003eclay bar\u003c\/a\u003e for anything the chemistry didn't lift.\u003c\/p\u003e\n\n\u003cp\u003eWhere Q²M Iron hits its limits: on cars that have sat in road use for more than 6 months without decontamination, the iron particles have worked so deep into the clearcoat that even two passes won't lift it all. In that case a follow-up polish helps to mechanically take down the remaining inclusions.\u003c\/p\u003e\n\n\u003cp\u003eQ²M Iron pulls out the free and near-surface particles — the deeply embedded ones are a job for the machine polisher. It's also not the first pick against baked-on brake dust on wheels that's eaten in over months: there the more concentrated Iron WheelCleaner does the job, while Q²M Iron is built for the whole car.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/gyeon-q2m-iron-ergebnis-violette-reaktion.jpg?v=1776067919\" alt=\"GYEON Q²M Iron purple colour change on a paint surface, close-up\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eBefore every polish. No exceptions.\u003c\/h3\u003e\n\u003cp\u003eQ²M Iron belongs in every detailing workflow between the wash and the polish — whether it's a full detail or a thorough weekend session in the garage at home. The full decontamination sequence: wash, chemical decontamination (Iron + Tar), mechanical decontamination (clay), then and only then polish and coating. Skip this step and you polish iron particles into the clearcoat instead of removing them.\u003c\/p\u003e\n\n\u003cp\u003eThe reason is physical: iron particles are harder than clearcoat. When you run a machine polisher over contaminated paint, the pad drives the particles deeper into the material instead of taking them off. It looks good at first because the polish smooths the paint around the particles. But under the new surface the iron inclusions are still there — and they keep oxidising for weeks. So Q²M Iron before the polish isn't a suggestion, it's damage prevention.\u003c\/p\u003e\n\n\u003cp\u003eQ²M Iron also earns its place in the regular care between full details: laid down on washed paint every 2–3 months, it stops iron particles building up and keeps the paint surface decontaminated. That matters most on cars with a ceramic coating: the coating layer protects the clearcoat, but iron particles settle on the coating too and can attack it over time.\u003c\/p\u003e\n\n\u003cp\u003eAfter the Iron treatment it's worth topping up the coating — either wet with a wet-coat sealant or dry with a spray coating. That's the full care workflow in under 20 minutes: wash, Iron, rinse, seal. A typical sulphur smell during use is normal and shows the active ingredient reacting with the iron oxides — it clears completely once you rinse off.\u003c\/p\u003e\n\n\u003cp\u003eThe three sizes cover different scenarios: 500 ml for 3–4 cars during regular washing, 1 litre as the standard size for the keen home user, 4 litres for detailers and busy operations running several cars a week.\u003c\/p\u003e\n\n\u003cp\u003eAt about €6 per use (500 ml bottle, ~150 ml per car), Q²M Iron isn't a luxury product — it's standard kit for anyone who wants to keep their paint healthy long term.

Tar is a mixture of aromatic hydrocarbons that liquefy when heated and adhere to paint surfaces. Tree sap contains terpenes and resin acids that cross-link with UV radiation and become increasingly harder over time. Mechanical removal without a suitable solvent inevitably causes scratches – the contamination is harder than the paint surface and would act like sandpaper.\u003c\/p\u003e\n\u003cp\u003eThe right product first chemically dissolves the contamination, reduces its adhesion, and then makes it accessible for mechanical blotting. GYEON Q²M Tar is formulated precisely for this – the solvent component penetrates the tar or resin layer, dissolves the bond to the paint surface, and enables gentle, scratch-free removal.\u003c\/p\u003e\n\n\u003ch3\u003eStep-by-step application\u003c\/h3\u003e\n\u003cp\u003eBefore treating with Q²M Tar, wash the vehicle normally to remove loose surface dirt. Leave the affected area dry or slightly damp – depending on product instructions. Spray Q²M Tar directly onto the contamination and let it dwell for 1 to 2 minutes. Dab with a clean, soft microfiber cloth, do not rub – this absorbs the dissolved contamination without spreading it on the surface.\u003c\/p\u003e\n\u003cp\u003eFor stubborn residues, repeat the process. Never apply excessive mechanical pressure – Q²M Tar is formulated so that patience and chemistry do the work, not brute force.

Heat makes the product flash off too fast and leaves alkaline residue that's a pain to get off. If you want to clean straight after a long drive: cool the bonnet and bumpers down first with a quick blast of water, then spray. Let it dwell for 3 minutes max. A second pass always beats a longer dwell on the first one.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray on. 3 minutes. Rinse off.\u003c\/h3\u003e\n\u003cp\u003eGYEON Q2M Bug Grime goes on before the actual wash as a pre-wash. It chemically softens bug residue and road film so you don't need any mechanical pressure during the wash itself – that cuts the scratch risk during contact washing right down.\u003c\/p\u003e\n\n\u003cp\u003eSpray the product evenly onto the dry, cool surface – the front end, bumpers, windscreen, mirrors and A-pillars are the usual bug zones. Work from the bottom up so the product doesn't run off too fast and the dwell time stays even.\u003c\/p\u003e\n\n\u003cp\u003eAfter 2–3 minutes, rinse top to bottom with a pressure washer or a strong jet of water. The softened bug residue flows away with the water, no need to touch the surface. Then carry on washing as normal with \u003ca href=\"\/en\/products\/gyeon-q2m-bathe-autoshampoo\"\u003ecar shampoo\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eTiming matters: don't let it dwell longer than 3 minutes. The surfactants in Bug\u0026amp;Grime are saturated after that – a longer dwell adds no cleaning power but does raise the risk of residue on the surface. That's especially true in summer above 25 °C, when the product dries faster.\u003c\/p\u003e\n\n\u003cp\u003eWith stubborn bug residue that's been baked on for days, a single pass won't lift everything. Lay down a second pass and gently agitate with a soft detailing brush. The brush spreads the product and brings fresh surfactants onto the dirt – more effective than a longer dwell.\u003c\/p\u003e\n\n\u003cp\u003eFor spot treatment on the road, Bug\u0026amp;Grime works fine without a pressure washer too: spray straight onto the spot, let it dwell 2–3 minutes and lift it off gently with a damp microfibre, dabbing rather than wiping. Don't wipe over the bug residue – dab the softened material off, that way you avoid scratches even without a water supply.\u003c\/p\u003e\n\n\u003cp\u003eOne more detail for glass: Bug\u0026amp;Grime works just as safely on windscreens as on paint. Bugs on the windscreen are often more of a nuisance than on the bonnet, because they block your view and the wipers just smear the residue around. Spray Bug\u0026amp;Grime onto the dry glass, let it dwell and rinse off – after that the wiper clears streak-free again.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/anwendung-bug-grime.jpg?v=1776026163\" alt=\"GYEON Q2M Bug Grime being sprayed onto a bug-covered vehicle front end\" loading=\"lazy\" width=\"1200\" height=\"800\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eIt dissolves bugs. Not bug etching.\u003c\/h3\u003e\n\u003cp\u003eBug\u0026amp;Grime reliably removes fresh and dried-on bug residue from the paint surface – that's its core job. On top of that, the cleaner lifts road grime films, light tar spots and the typical summer film of pollen and dust off bonnets and windscreens.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: bug etching in the clear coat. When bug residue sits on the paint in the sun for days, the acids in it chemically etch the clear coat. These etch marks are physical damage to the paint surface – no cleaner can remove them.\u003c\/p\u003e\n\n\u003cp\u003eFor that you need a paint polish to take down the damaged clear coat layer and expose a fresh one. Bug\u0026amp;Grime prevents etching like this by removing the bug residue in time. If you clean within 24 hours of every motorway run, you generally won't find any etch marks.\u003c\/p\u003e\n\n\u003cp\u003eLeave it a week and you have to expect paint damage – especially on dark cars, which heat up more in the sun. Dark paint soaks up more heat, the bug acids react faster, and the etching goes deeper. Here, acting fast is the best paint protection there is – a 500 ml bottle in the boot costs 13 EUR and can save you polishing costs of 200 EUR and up.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: tar and tree sap. Bug\u0026amp;Grime is formulated for protein-based grime (bugs, bird droppings, biofilm). Hydrocarbon contamination like tar, bitumen and tree sap doesn't react to alkaline surfactants – for that, \u003ca href=\"\/en\/products\/gyeon-q2m-tar-redefined-harzentferner-teerentferner\"\u003eQ²M Tar\u003c\/a\u003e is the right product.

As a pre-wash before every summer wash, the bug remover cuts the scratch risk noticeably. Especially relevant for cars with a ceramic coating or fresh polish, where every micro-scratch shows.\u003c\/p\u003e\n\n\u003cp\u003eIn the Detailing1 wash workflow, Bug\u0026amp;Grime sits right at the start: Bug\u0026amp;Grime on the front → \u003ca href=\"\/en\/products\/gyeon-q2m-foam-schaumreiniger\"\u003eQ²M Foam\u003c\/a\u003e as a pre-foam over the whole car → main wash with Q²M Bathe or Q²M Bathe+ → optionally Q²M WetCoat as a wet sealant. Four steps, under 30 minutes, and the front is clean without a single scratch.\u003c\/p\u003e\n\n\u003cp\u003eBug\u0026amp;Grime takes on the hardest part of the workflow: dissolving the protein-bound grime that the foam cleaner can't handle on its own. Foam softens surface dust and road grime, but dried bug proteins need the higher pH of a dedicated bug remover. The difference is measurable: after a pre-wash with Bug\u0026amp;Grime the wash mitt glides over the front end with no resistance during contact washing – without Bug\u0026amp;Grime you feel every dried bug as drag under the mitt.\u003c\/p\u003e\n\n\u003cp\u003eWhere Bug\u0026amp;Grime is less suited is as a replacement for a full pre-cleaner. If you want to clear road grime off the whole car, you're better off reaching for Q²M Foam as a pre-foam – it covers every surface and lifts general dirt more efficiently than a bug remover. Bug\u0026amp;Grime stays the specialist tool for the front and any spots with bug contamination.\u003c\/p\u003e\n\n\u003cp\u003eIf you only remove bugs now and then and don't need a regular workflow: the 500 ml spray bottle fits in any driver's door and is ready to go as a spot treatment. Spray it on the front right after the motorway, let it dwell, rinse it off at the next self-service bay.\u003c\/p\u003e\n\n\u003cp\u003eIt's the simplest insurance against bug etching in summer. For year-round use or several cars, the 4-litre canister is worth it: same formula, lower price per litre at 15.50 EUR per litre instead of 26 EUR with the 500 ml bottle.

The product pH sits at around 2 and it's formulated with lubricating-oil carriers that keep marring off the paint while you work.\u003c\/p\u003e\n\n\u003cp\u003eThat approach is what fundamentally sets the Q²M WaterSpot apart from a mechanical polish. Limescale comes off purely chemically — no paint removal, no holograms and no risk to thin clear-coat layers.

The lubricating-oil component flashes off in seconds and you end up wiping oily streaks instead of dissolved limescale. Always work in the shade, with paint below 25 °C, and never let the product sit longer than 30 seconds. After you pull it off, follow up with an alcohol-based degreaser or a pH-neutral wash to clear the oil residue — otherwise you've just built yourself a dirt-magnet surface.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold paint. 30 seconds.

The Q²M WaterSpot needs a washed, dried and cool surface — then the acid reaction kicks off evenly. Spray straight onto the limescale spots from about 15 to 20 centimetres away, one to two sprays per panel (around 15 ml).\u003c\/p\u003e\n\n\u003cp\u003eMaximum dwell time is 30 seconds, not a second more. Then pull it off in one direction with a soft, clean microfibre cloth. A common mistake day-to-day is the idea that a longer dwell time would dissolve stubborn spots better. The opposite is true: past 45 seconds the phosphoric-acid solution starts to dry on, and the lubricating-oil component no longer lifts off evenly with it.\u003c\/p\u003e\n\n\u003cp\u003eFor stubborn or slightly dried-on water spots you work in two passes: pull off the first application after 30 seconds, then immediately spray a second layer onto the same spot and pull that off after 30 seconds too. The second pass lands on a surface that's already been chemically primed and lifts the residue the first pass didn't catch.\u003c\/p\u003e\n\n\u003cp\u003eTo finish, rinse the treated area with clean water or wipe it down with a second microfibre cloth and a little shampoo water. This after-clean isn't optional — it's a fixed part of the workflow: Q²M WaterSpot leaves a thin oil film that attracts dust and pollen until it's washed off.

On evaporated hard water and rain, though, the product works reliably: calcium and magnesium carbonates get converted chemically into water-soluble salts that wipe off the paint in a single pull.\u003c\/p\u003e\n\n\u003cp\u003eThat's the real dividing line for the buying decision. Silica-based GYEON ceramic coatings are chemically stable enough to take 30 seconds of contact with phosphoric acid at pH 2 unharmed — one of the upsides you installed the coating for in the first place. Carnauba wax layers, synthetic sealants and hybrid wax-coatings can't handle that load and get partly or fully stripped.\u003c\/p\u003e\n\n\u003cp\u003eThe result isn't paint damage, but a rebuild of the protective layer. If you look after your car every three months with a spray wax, every WaterSpot pass means: water spots gone, wax layer gone, wax back on. On active ceramic coatings that step drops out, because the coating stays put.\u003c\/p\u003e\n\n\u003cp\u003eThe clear limits: limescale that's baked in after months of neglect often can't be fully dissolved chemically any more — by then calcium has worked its way into the clear coat and only a light finishing polish takes out the rest.

The south, Franconia and big parts of Saxony-Anhalt with water hardness above 14 °dH throw up these marks in particular: the hydrophobic layer beads the water but doesn't always let it run off completely, and the leftover water dries in at the lowest point of a droplet. The Q²M WaterSpot is the routine that stops these marks before they're polish-only.\u003c\/p\u003e\n\n\u003cp\u003eThe product also makes sense for anyone who lets their car dry outside after a wash for lack of a garage. When the leftover water evaporates in the sun, you're left with the characteristic water spots that shampoo won't lift any more.

However, this process requires a lubricating film between the clay and the paint to avoid scratches. An unsuitable lubricant (e.g., normal all-purpose cleaner) can absorb the clay mass too quickly, leave soap residues, or distribute the lubricating film unevenly. Q²M ClayLube is formulated for precisely this application: maximum lubricating effect, minimal residues, optimal claying temperature.\u003c\/p\u003e\n\n\u003ch3\u003eWhen should paint clay with Q²M ClayLube be used?\u003c\/h3\u003e\n\u003cp\u003eThe rule of thumb: After every complete vehicle detailing (1–2 times annually) and whenever the paint feels rough (the \"sandwich bag test\" – rough = contaminated). Typical indications are: after winter (road salt, brake dust), after stays near industrial plants (industrial fallout), before preparation or coating application.

Let \"Pe\" hit a strip like that too strong or too long and the alkali eats into the layer, leaving milky-white, iridescent marks. They won't polish out; the strip has to be replaced. On bare or polished alloy the metal reacts on contact and dulls right off.\u003c\/p\u003e\n\u003cp\u003eOn intact clear coat, though, \"Pe\" is safe as long as you hold the minute. Modern clear coats are highly cross-linked polymers that shrug off a short alkaline spike with no trouble; dilute to 1:100 and the working pH on the paint drops into the 11 to 12 region anyway. Steel wheels and powder-coated, alkali-resistant alloy wheels take the stronger wheel dose — all that matters is the wheel isn't bare, anodised or mirror-polished.\u003c\/p\u003e\n\u003cp\u003eThe second hard line is heat. On a sun-warm bonnet the water in the solution flashes off in seconds, the alkali concentrates back up in spots and etches the clear coat. What's left is baked-in tide marks that only a machine polish removes. So the rule stands: never in full sun, never on hot metal.\u003c\/p\u003e\n\u003cp\u003eAnd \"Pe\" doesn't tell the difference between dirt and a protective layer. A product around pH 13 is as caustic as a drain cleaner and strips waxes, sealants and weaker coatings clean off. That's exactly why it's not a maintenance product. If you want to wash your waxed or ceramic-coated car gently, stick to the pH-neutral \u003ca href=\"\/en\/collections\/autoshampoo\"\u003ecar shampoo\u003c\/a\u003e; \"Pe\" would take the protection off along with the dirt.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-prewash-express-pe-vorreiniger_ergebnis.jpg?v=1780346992\" alt=\"Clean rinsed front end after the pre-wash, Pe pre-wash standing next to it\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for high-throughput washing, not the weekend\u003c\/h3\u003e\n\u003cp\u003e\"Pe\" earns its keep where speed matters: in express car washes, on fleets, commercial vehicles and badly soiled cars — not on a relaxed weekend wash in the driveway.\u003c\/p\u003e\n\u003cp\u003eIn the wash tunnel that short, no-compromise action is an upside: the plant meters precisely, cycles fast and rinses through quickly thanks to the low foam. For the detailer working by hand, that's the catch. The VDA minute is gone fast once you've walked a big SUV with the pump sprayer — by the time you're back, the concentrate at your starting point has been sitting far too long. So you work \"Pe\" in sections: spray one side, rinse, then the next.\u003c\/p\u003e\n\u003cp\u003eDetailers reach for \"Pe\" as a dirt-breaker on purpose, not as an all-rounder: for neglected used cars, winter salt crust, engine bays, or to strip wax before a polish and re-seal. Within the Koch-Chemie line-up it's the top energy stage. If you want the classic, higher-foaming pre-wash for longer dwell times, the sister product \u003ca href=\"\/en\/products\/koch-chemie-vorreiniger-b-vb-vorreiniger\"\u003eVorreiniger B\u003c\/a\u003e is the better fit; \"Pe\" is the low-foam, express-tuned option in the \u003ca href=\"\/en\/collections\/vorreiniger\"\u003ePre-wash\u003c\/a\u003e range.\u003c\/p\u003e\n\u003cp\u003eThe numbers stack up mostly in volume work. A 23 kg drum makes around 2,300 litres of finished pre-wash solution at 1:100 — enough for hundreds of cars. Spread across a single wash the product cost barely shows; the real lever is the time the short dwell phase saves per car. For a handful of cars a month the 5 kg pack lasts a long while instead, with no concentrate ageing unused.\u003c\/p\u003e\n\u003cp\u003eThe pack sizes follow that logic: 5 kg to get started and for smaller operations, 23 kg as the standard drum for a running plant, 225 kg in the barrel for high-frequency wash tunnels with automatic dosing. The one thing no label spells out: the maximum dwell time isn't a suggestion, it's the safety limit. \"Pe\" is built for the machine that's done in 60 seconds. Respect that by hand and work in sections, and you get the full dirt-cutting power without ever risking a trim strip.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-prewash-express-pe-vorreiniger_lineup.jpg?v=1780346999\" alt=\"Koch-Chemie PreWash express Pe packs, 5 kg and 23 kg side by side\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"5kg","offer_id":57637056315727,"sku":"D1-KCX-296005","price":21.59,"currency_code":"EUR","in_stock":true},{"title":"23 kg","offer_id":57637109694799,"sku":"D1-KCX-296023","price":89.99,"currency_code":"EUR","in_stock":true},{"title":"225kg","offer_id":57637109727567,"sku":"D1-KCX-296225","price":875.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-prewash-express-pe-vorreiniger_c84633b8-b584-42a7-a8d8-5f3a21695246.png?v=1780347129"}],"url":"https:\/\/detailing1.de\/en\/collections\/vorreiniger.oembed?page=2","provider":"Detailing1","version":"1.0","type":"link"}
