Dark Fury is a concentrated cleaner made specifically for tires and wheels. Dilute the product 4:1 for the most efficient cleaning power. You can dilute up to 10:1 but we have found that 3:1 to 5:1 works the best. This product performs like an acid wheel cleaner without the acid. It is a very unique product. Spray directly on the tire and rinse the dirt and grease clean. Dark Fury complemented with a pressure washer will make your rim and wheel sparkle. Dark Fury is a great exterior cleaner for just about any vehicle. Great at removing bugs, mud from ATV's, road grime, cleaning trailers and gutters. Clear coated surfaces only. Just be sure to dilute Dark Fury at least 4:1 for optimal cleaning capabilities. For use on clear coated surfaces.
