GYEON Q²M APC All-Purpose Cleaner 4000ml

One cleaner for everything – GYEON Q²M APC All-Purpose Cleaner

What is GYEON Q²M APC? GYEON Q²M APC is a highly concentrated all-purpose cleaner for every area of the car – depending on how you dilute it, you can tackle stubborn interior stains, exterior pre-wash, engine bay cleaning and plenty more, all with a single product.

If you'd rather not own a separate specialist product for every cleaning job, GYEON Q²M APC is a powerful alternative. As a highly concentrated all-purpose cleaner (APC), it covers a wide range of jobs through variable dilution: heavily diluted for sensitive interior materials, less diluted for stubborn stains and grime on tyres or in the engine bay, neat for extreme dirt. One concentrate – many uses.

• Variable dilution for maximum flexibility. Q²M APC can be used differently depending on the job: 1:10 for interior and delicate fabrics, 1:5 for rubber seals and plastics, 1:2 or neat for engine bay cleaning, wheel arches and stubborn exterior grime. One product replaces a whole shelf of specialist cleaners.
• Cuts through grease, oil and organic grime. Q²M APC goes after grease, oils, bugs, bird droppings and organic residue effectively – without leaning on harsh acids or strong alkalis. The formula is built for use on cars and stays kind to surfaces when you dilute it correctly.
• A concentrate – easy on the wallet. APC concentrate offers seriously good value: one litre of concentrate makes up to 10 litres of ready-to-use cleaner (at 1:10 dilution). That makes GYEON Q²M APC one of the most economical cleaners in the detailing range.

Detailing1's tip from the shop: For interior cleaning, always start with the weakest dilution that works and step it up if you need to – that's how you look after materials like Alcantara, Nappa leather or coated plastics. Never put APC on neat over delicate surfaces. Outside, use it as a pre-cleaner before the actual wash with Q²M Bathe – it loosens the heavy dirt first and makes the hand wash that follows far easier.

Where Q²M APC earns its keep day-to-day

GYEON Q²M APC is one of the most versatile cleaners in detailing. Typical jobs: interior cleaning (dashboard, door cards, plastic or fabric seats), carpet and fabric pre-cleaning before the Q²M FabricCleaner, tyre cleaning as prep for tyre dressing, wheel arch cleaning, engine bay cleaning on moderate grime, lifting bugs and bird droppings as a pre-spray before the wash, plus cleaning sills and underbody. Not suited to sealed or polished paint surfaces when used without a coating to follow.

The dilution strategy: dosing Q²M APC right

The versatility of Q²M APC comes from its concentration and the variable dilution. The rule of thumb: the more delicate the surface, the more you dilute. For Alcantara and leather: 1:10 to 1:20 – barely aggressive, still effective. For carpets and fabric seats: 1:5 to 1:10 – strong enough for stain removal. For plastics, seals and exterior rubber: 1:3 to 1:5. For tyres, wheel arches and engine bay: 1:2 to neat. For stubborn oil stains or industrial grime: spray on neat, give it a short dwell, then rinse off with water.

Q²M APC as a pre-cleaner in a full detail

In a proper detail, an all-purpose cleaner is something you can't do without. GYEON Q²M APC typically comes in during the prep stage: before the actual paint correction you pre-clean every surface, loosen bugs and bird droppings, and clear the interior of fingerprints and greasy marks. The next step is then Q²M Tar for tar and resin residue, Q²M Iron for fallout removal, and Q²M Prep as the final degreaser before the coating goes on.

Q²M APC vs. specialist cleaners: when is an APC enough?

An all-purpose cleaner handles plenty of jobs, but not all of them equally well. Q²M APC is brilliant for general cleaning and moderate dirt. For specialised jobs, dedicated products do better: on heavy fallout Q²M Iron is far more effective (a reactive iron remover), on a wall of bugs Q²M Bug&Grime is the better pre-wash, and for heavy leather stains Q²M LeatherCleaner Strong is the call. Q²M APC sits alongside these specialists perfectly as the universal base cleaner.

Our take: Q²M APC – the base product you can't skip

GYEON Q²M APC is a must-have for any detailing collection. The mix of high efficiency, concentration and versatility makes it one of the best value-for-money products in the entire Q²M range. To round it out for full interior cleaning we'd add the Q²M FabricCleaner for fabrics and the Q²M LeatherCleaner Natural for leather care – together with Q²M APC that's an efficient, complete interior cleaning combo.
