No doubt that after several years of brake dust, the clear coat on the alloy wheels may discolor. And the best way to return them to their proper state is to have them professionally refinished.
At Alloy Wheel Repair we can protect your alloys from brake dust marks. Brake dust is considered to be highly corrosive and that is why it can pit and discolor your wheels. We can make their cleaning process easier using a quality car wax on your rims, so in this way we protect them from dirt and brake dust marks.
If discoloration caused by brake dust marks do not clear up with the polish method, your only options are to repaint or have them refinished professionally. You can do both things at Alloy Wheel Repair. We can refinish your dull alloy wheels and make them shine like new again.
