The thick foam formula that makes up this car care product clings to wheels and tires, penetrating the toughest grime. The foaming gel dissolves and removes road grime, brake dust, tar, oxidation, grease, oil, and dirt. Our Stoner car cleaner uses an acid-free and pH neutral formula that is safe for all types of tires, wheels, rims, and hubcaps. It can be used on aluminum alloy, steel, anodized, clear or color-coated, factory painted, modular, or chrome wheels. This product is sold as a single, easy-to-use 16-fluid ounce spray bottle.
