Turtle Wax Redline Wheel Cleaner is a unique pH-neutral wheel cleaner with active sodium ingredients that turn red as they remove brake dust quickly and safely. To use: spray, wait for colour change and then power wash to remove all contaminants. Redline Wheel Cleaner has a non-acidic formula which is safe for all alloys, decals and wheel nuts, and can be left for much longer than aggressive acidic or alkaline based cleaners. No hard brushing or agitation is required. Size: 500ml
