It reacts with embedded brake dust and iron fallout, discolouring red as it does, and lifts the contamination out of the wheel face and barrel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\"Acid-free\" needs a definition.\u003c\/strong\u003e In rim cleaners it means free of the aggressive mineral acids the category was built on — hydrofluoric acid and ammonium bifluoride — which etch clearcoat, damage polished lips and are genuinely dangerous to handle. It does not mean pH-neutral. Magic Wheel Cleaner measures \u003cstrong\u003epH 5–6\u003c\/strong\u003e on Koch Chemie's own safety data sheet: mildly acidic, which is where the formulation needs to sit for the iron chemistry to work. Mildly acidic is a completely different proposition to fluoride-based, and that is the distinction that actually matters for your wheels.\u003c\/p\u003e\n\u003cp\u003eThe viscosity is deliberate. Sprayed on, it clings to a vertical wheel face and stays wet through the full dwell instead of running off or flashing dry, so the reaction has time to finish before you rinse.\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eKEY FEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo hydrofluoric acid, no ammonium bifluoride.\u003c\/strong\u003e None of the fluoride chemistry that etches clearcoat and attacks polished and anodised finishes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH 5–6, verified.\u003c\/strong\u003e Taken from the manufacturer's safety data sheet rather than a marketing line.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour-change indicator.\u003c\/strong\u003e The red discolouration marks exactly where iron is being dissolved.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-cling viscosity.\u003c\/strong\u003e Holds on vertical surfaces and resists drying out over an extended dwell.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated surfaces.\u003c\/strong\u003e Painted alloy wheels, high-quality chromed wheels and steel rims.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cstrong\u003eDIRECTIONS\u003c\/strong\u003e\u003c\/h5\u003e\n\u003col\u003e\n\u003cli\u003eWork on cool wheels, out of direct sunlight.
