GRIOT'S GARAGE TIRE CLEANER Unleash the power of foam to cut through brake dust and road grime, strip away silicone residue, and prepare your tires for dressing. Safe for use on black, whitewall, and raised-white-lettered tires, Foaming Tire Cleaner is easy to use. Simply spray on a thick layer, let the foam come alive, and leave it to sizzle for 3 to 5 minutes. Once the foam takes on a brown hue, agitate if needed, rinse or wipe your tire clean, then reach for your favorite dressing.
