Brake dust is usually caused by brake pads. Normal brake usage causes flakes of metal, Kevlar or other monofilament carbon fibers to collect around the brake components and an automobile's wheels. When this dust meets with moisture, it can cause long-term damage to your car. Therefore, it's important to clean brake dust periodically.

 

Select a cleaning chemical to clean away brake dust. While there are any number of chemicals that are safe to use, consider buying one of the specialty products designed for use on brake dust. You can find these products at an automotive repair shop.

 

Spray a modest amount of the cleaning chemical into a rag. Use a clean cotton or microfiber fabric. Not all fabrics are ideal for cleaning brake dust.

 

Scrub the inside of each tire and wheel. Take your time and pay attention to any places where you may notice deposits of collected brake dust.

 

Spray cleaning fluid directly onto the exterior walls of your tires. Use a nylon brush to remove any remaining brake dust. Refrain from using a metal brush on your delicate rubber tires.

 

Rinse your tires and wheels clean by using water and a hose. Make sure to spray water along the underside of your wheels to remove all traces of brake dust.
