Use the Right Tools
To clean brake dust, which forms when the brake pad wears out due to braking, use a pressure washer or hose to remove most of the dust. For the remaining residue, use a soft-bristled paintbrush and your regular car shampoo. Avoid using strong and acidic brake cleaners, as they can damage and dull your wheel finish. Gentle soap with water is always the best choice for keeping your wheels shiny and clean.
