Dr. Wack relies on a highly active surfactant system with a special complexing agent based on \u003ci\u003esodium mercaptoacetate\u003c\/i\u003e. This molecule reacts specifically with metallic brake residue (mainly iron oxides) and dissolves it without attacking the sensitive metals or paint. The colour change – from clear to violet – shows the active cleaning phase. Thanks to the gel structure, the cleaner stays put even on vertical surfaces, which clearly boosts dwell time and cleaning power. The high viscosity makes sure brake dust deep in the pores gets broken down too, before it's rinsed away completely. The result: evenly clean wheels with their original shine – no scrubbing, no micro-scratches.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eApplication and day-to-day tips for perfect results\u003c\/h3\u003e\n\u003cp class=\"p3\"\u003eUsing the \u003cspan class=\"s2\"\u003e\u003cb\u003eP21S POWER GEL wheel cleaner\u003c\/b\u003e\u003c\/span\u003e is easy, but like with proper detailing you want to be deliberate about it. Spray the product evenly onto the dry, cooled-down wheel. Thanks to the gel grip a thin film forms right away that clings even in hard-to-reach spots – between spokes, in the wheel barrel or behind the bolts. After about 3–5 minutes of dwell time the cleaner turns dark red to violet: that's the sign brake dust and metal particles are actively being dissolved. Then just rinse it off with a strong water jet or pressure washer. For a perfect finish on badly neglected wheels you can help things along with a soft wheel brush. Important: don't let it dry on, and don't use it in direct sun. Since the cleaner is completely acid-free, the risk of corrosion or dull spots stays at zero – even on polished alloys or sensitive multi-piece wheels. It's also TPMS-compatible and biodegradable, so it's safe in everyday use. After cleaning, a wheel sealant is worth doing to make fresh dirt stick less.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eResults, durability and use cases\u003c\/h3\u003e\n\u003cp class=\"p3\"\u003eWhat we see day-to-day is that the \u003cspan class=\"s2\"\u003e\u003cb\u003eP21S POWER GEL\u003c\/b\u003e\u003c\/span\u003e delivers an extremely clean, even finish with no residue. Brake dust, oil and tar particles come off completely, the wheel surface feels smooth and clean – the perfect base for follow-up care or a sealant. Hard-driven cars or vehicles with open brake setups in particular benefit from the strong yet gentle cleaning. The gel-like formulation makes the product go a long way, since less cleaner runs off the wheel. Thanks to its pH-neutral action the POWER GEL doesn't attack paint, plastic parts or valves and can be used regularly. It's ideal for classics, chrome wheels or multi-piece alloys too – even with frequent use you get no stains or changes in the surface structure. The difference is visible and tangible straight away: smooth, glossy wheels with no residue – and all in a few minutes.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cb\u003eCommon questions about Dr. Wack P21S POWER GEL wheel cleaner\u003c\/b\u003e\u003c\/h4\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eHow long should the P21S POWER GEL dwell? \u003c\/b\u003e\u003cb\u003e\u003c\/b\u003e3 to 5 minutes is plenty.
