An alkaline heavy-duty cleaner with pH 12.5 that breaks down oils, grease, nicotine, soot and grey ingrained dirt on fabric, plastics and industrial surfaces — a concentrate you dilute anywhere from 1:5 to 1:50. Keep it off soft-touch surfaces, leather and painted panels.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie Mzr\u003c\/strong\u003e is an alkaline cleaner concentrate from Koch-Chemie that chemically lifts stubborn organic dirt out of pores and fibres. The pH of 12.5 in the concentrate saponifies fats and oils through alkaline hydrolysis — something pH-neutral cleaners simply can't do chemically. Dilute it 1:10 and you sit around pH 11, which is plenty for most interior surfaces in the car. Koch-Chemie has it under an official Daimler approval, which is why detail shops and workshops keep it on the shelf as a default.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_hero.png?v=1776196784\" alt=\"Koch-Chemie Mzr 1L bottle next to the open door of a black Mercedes-AMG GT in the warehouse bay\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDilute from 1:5 to 1:50 — one concentrate for any kind of dirt.\u003c\/strong\u003e For heavy jobs like motor oil or nicotine films you work at 1:5. For everyday interior cleaning 1:20 to 1:50 is plenty. One litre of concentrate at 1:20 makes 21 litres of working solution — at €7.67 a litre that's €0.37 per litre of ready-to-use cleaner.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCuts through what pH-neutral cleaners leave behind.\u003c\/strong\u003e Nicotine, greasy fingers on headliners, ingrained grey on light fabric seats — these are the jobs where the Mzr earns its keep. The alkaline formula saponifies fatty acids and emulsifies oil residue rather than just pushing them around the surface. Where a neutral \u003ca href=\"\/en\/products\/koch-chemie-allround-surface-cleaner-asc-allzweckreiniger\"\u003eall-purpose cleaner\u003c\/a\u003e needs two passes, the Mzr does it in one.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDaimler approval for workshop use.\u003c\/strong\u003e The official approval confirms material compatibility on Mercedes-Benz factory fabrics and plastics. Detail shops, fleet managers and independent workshops keep it as their standard interior cleaner — one concentrate for the whole fleet instead of a shelf full of specialty bottles.\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 Never spray the Mzr neat onto a surface — pH 12.5 in the concentrate attacks soft plastics and pigments. Always dilute in the bottle first and start at 1:10. If that does the job, dial down to 1:20 next time. The most common mistake we see day-to-day: people run the dilution too strong and end up with white patches on dark plastics because the alkalinity has attacked the surface. Two passes at 1:10 give you a better, more even result than one pass at 1:5.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:10 on the headliner. 1:50 on the door handle.\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie Mzr works as a concentrate that you dilute fresh for every job. That sets it apart from ready-mixed \u003cstrong\u003einterior all-purpose cleaners\u003c\/strong\u003e like the \u003ca href=\"\/en\/products\/koch-chemie-multi-interior-cleaner-innenraumreiniger-750ml\"\u003eKoch-Chemie MultiInteriorCleaner\u003c\/a\u003e, which come at a fixed strength you can't change.\u003c\/p\u003e\n\n\u003cp\u003eFor a nicotine-stained headliner or greyed fabric seats you work at 1:5 to 1:10. Spray it on evenly, let it dwell for 1–3 minutes, then work it in with a soft detailing brush in circles. The Mzr lifts the dirt chemically, the brush pulls it out of the fibres. After that you extract the dissolved soil with a clean microfibre or a wet vac. On headliners the wet vac is non-negotiable — too much standing moisture softens the textile glue and the headliner starts to sag.\u003c\/p\u003e\n\n\u003cp\u003eFor everyday interior cleaning — dash, centre console, door cards — 1:20 to 1:50 is enough. At that strength the Mzr is gentle enough for most hard plastics. The surface comes out clean and there's no greasy film left behind.\u003c\/p\u003e\n\n\u003cp\u003eRight after that you can lay down a plastic dressing — the Mzr leaves no residue that would block adhesion. That's what makes it the go-to prep step before any dressing. Still: on soft-touch steering wheels and rubberised grips even the weakest dilution is a gamble. Grab a pH-neutral cleaner for those.\u003c\/p\u003e\n\n\u003cp\u003eOutside the cabin the Mzr earns its name too: workshop floors with oil stains, grimy industrial machines, weathered motorhome trim. For outdoor use go 1:5 to 1:10 and let it dwell 3–5 minutes. Hit it with a pressure washer or a brush, then rinse off.\u003c\/p\u003e\n\n\u003cp\u003eOne detail Koch-Chemie doesn't flag on the product page: the Mzr leaves a subtle, clean scent on the surfaces it cleans. Not an artificial air freshener — just noticeably less chemical than comparable industrial cleaners. In a smoker's car it won't mask the nicotine smell, but after the clean the cabin smells neutral instead of like cleaning chemicals. Sounds like a side-effect, but in the bay it matters when you're prepping cars for resale or hand-back.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_anwendung.png?v=1776198150\" alt=\"Headliner cleaning with diluted Koch-Chemie Mzr from an iK Multi TR 1 spray bottle in a Mercedes-AMG GT\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eKoch-Chemie Mzr lifts nicotine films. Leather, it attacks.\u003c\/h3\u003e\n\u003cp\u003eOrganic dirt is the home turf of Koch-Chemie Mzr: greasy fingerprints, nicotine films, soot, ink stains and that typical grey ingrained look on light upholstery after two years of daily use. The alkaline formula handles those in one pass.\u003c\/p\u003e\n\n\u003cp\u003eThe colour shift from clean to dirty is instant on the Mzr — the microfibre after a wipe shows exactly what came out of the surface. Most dramatic on greyed light fabric seats: the first pass often pulls two shades of difference out. That's not a marketing line — it's the chemical effect of alkaline saponification breaking down the deep-set fat soiling that a neutral cleaner can't reach.\u003c\/p\u003e\n\n\u003cp\u003eKoch-Chemie positions the Mzr as an \u003cstrong\u003einterior all-purpose cleaner\u003c\/strong\u003e for cars, industry and building maintenance. The pack sizes tell you the same story: the 1-litre bottle sits next to 11 kg, 21 kg and 225 kg drums. This is a workshop cleaner that also works in the car interior. That origin is where the strength comes from — the Mzr is formulated for industrial grime, and that power follows it into the cabin.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Mzr isn't the right tool: on genuine and synthetic leather with open-pore structure the alkalinity can dry out the surface and leave discolouration. Leather wants a pH-adjusted leather cleaner. On soft-touch plastics and rubberised surfaces like steering wheels or shift knobs it leaves dull patches. On painted or wrapped panels an alkaline cleaner has no business at all — even diluted 1:50, the pH still sits above 9. When you need an \u003ca href=\"\/en\/collections\/universalreiniger\"\u003eall-purpose cleaner\u003c\/a\u003e with no risk for sensitive materials, the Koch-Chemie ASC is the safer pick — ready-mixed, pH-neutral, surface-agnostic.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_ergebnis.png?v=1776196797\" alt=\"Headliner before and after cleaning with Koch-Chemie Mzr – nicotine grey on the left, deep black alcantara on the right\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eOne drum of Koch-Chemie Mzr. 200 litres of working solution.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Mzr pays back on yield. One litre of concentrate at 1:20 dilution gives you 21 litres of ready-to-use cleaner — enough for 15–20 full interior cleans. At €7.67 a litre that works out to under €0.50 per car. If you detail regularly, grab the 11-kg drum: at €77.75 you're at €7.07 per kilo and around 200 litres of working solution at 1:20.\u003c\/p\u003e\n\n\u003cp\u003eThe Mzr is built for detailers, workshops and serious hobby detailers who want a concentrate over ready-mixed bottles. If you only clean the interior occasionally and don't want to mess with dilution, grab the MultiInteriorCleaner ready to use. If you want flexibility — stronger for a smoker's cabin, weaker for the weekly wipe-down — the Mzr is the cheaper bet.\u003c\/p\u003e\n\n\u003cp\u003eFor day-in, day-out workshop use we run a Koch-Chemie tap on the 11-kg drum: dose the concentrate into the bottle, top up with water, done. The 1-litre bottle is the one to keep for mobile work and the detailing kit. Store both frost-free between 5 and 30 °C; sealed concentrate keeps for 24 months. Use any diluted mix within four weeks.\u003c\/p\u003e\n\n\u003cp\u003eOne safety note to finish: the Mzr is classified as corrosive (H314) and carries the signal word \"Danger\". In the concentrate, always wear gloves and safety glasses. At normal working dilutions of 1:10 to 1:20 the risk drops a lot, but you still want to avoid prolonged skin contact. The safety data sheet is on the product page for download.\u003c\/p\u003e\n\n\u003cp\u003eBottom line: the Koch-Chemie Mzr isn't an everyday quick-wipe cleaner. It's a tool for jobs where you need to clean deep — smoker's cars, used-car prep, workshop floors, industrial machines. If those are your jobs and you're up for dilution and PPE, you get an \u003cstrong\u003einterior all-purpose cleaner\u003c\/strong\u003e that comes in at under €0.50 per car — hard to beat at that price.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_lineup.png?v=1776196804\" alt=\"Koch-Chemie Mzr 1 litre bottle and 11 kg drum on cobblestone in front of the warehouse with a Mercedes-AMG GT\" width=\"900\" loading=\"lazy\"\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48762462536015,"sku":"D1-KCX-86001","price":8.36,"currency_code":"EUR","in_stock":true},{"title":"2x 1000 mL","offer_id":49536037454159,"sku":"D1-KCX-86001_2","price":16.72,"currency_code":"EUR","in_stock":true},{"title":"3x 1000 mL","offer_id":49536037486927,"sku":"D1-KCX-86001_3","price":25.08,"currency_code":"EUR","in_stock":true},{"title":"11kg","offer_id":48762460307791,"sku":"D1-KCX-86011","price":79.97,"currency_code":"EUR","in_stock":true},{"title":"21kg","offer_id":49536024772943,"sku":"D1-KCX-86021","price":146.93,"currency_code":"EUR","in_stock":true},{"title":"225kg","offer_id":49536024805711,"sku":"D1-KCX-86225","price":1532.63,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-mehrzweckreiniger-mzr-universalreiniger.png?v=1714922290","url":"https:\/\/detailing1.de\/en\/products\/koch-chemie-mehrzweckreiniger-mzr-universalreiniger","provider":"Detailing1","version":"1.0","type":"link"}
