RCP's Sparkle is a professional-strength, citrus-scented, non-acid wheel and tire cleaner engineered to handle the dirtiest jobs without damaging delicate finishes. Designed to cling to the surface, it penetrates and dissolves brake dust, oil, road grime, and grease, leaving wheels and tires looking freshly detailed. Unlike harsh acid-based products, Sparkle is tough on buildup but safe enough to use on clear-coated, factory painted, and chrome wheels, and it's also the perfect solution for restoring white walls and raised white lettering to a bright, clean finish. Simply spray it on, let it cling and break down the grime, then agitate and rinse for that bright, detailed look. Paired with a dedicated wheel brush and an RCP drying towel, Sparkle takes your wheel detailing to the next level.
