Quicksilver Wheel & Tire Cleaner is ArmorAll's most concentrated formula for the toughest of debris, but safe on coated and aftermarket wheels when used as directed. Clinging formula sticks to the wheel and stays there allowing more time for cleaning agents to pull away brake dust, dirt and road grime. A must for wheels with hard-to-reach areas. For best results, spray evenly on dry, cool wheels. Let soak for 5 minutes. Hose off with strong water spray. Dry immediately with a clean, soft towel to prevent water spots and remove residual soils. No scrubbing needed!
