The Hi-Tech Whitewall and Tire Nylon Brush is a stiff nylon bristle brush purpose-built for scrubbing whitewall tires, white letter tires, and heavily soiled tire sidewalls back to a bright, clean appearance. The firm nylon bristles provide aggressive enough scrubbing action to remove embedded browning, road grime, and old dressing buildup from textured rubber surfaces without damaging the tire itself. Also works well for general tire cleaning on standard black sidewalls where thorough scrubbing is needed before dressing application.
