Your wheels are constantly under assault by grease, road grime and brake dust that get baked on during the intense heat of driving conditions. The Triple-Action Formula found in Armor All Extreme Wheel and Tire Cleaner is specifically formulated to attack ALL THREE -- grease, road grime, and brake dust -- dissolving them to reveal your beautiful, shiny rims. This triple-action cleaner is safe to use on all factory and aftermarket coated wheels when used as directed. Do not apply to brake parts or other zinc and cadmium-plated surfaces.
