What does it mean when you have a lot of brake dust on rims?
If you notice large amounts of brake dust on a wheel or notice brake noise, get a mechanic to review your brake system, as it can indicate a more serious issue — like worn springs in a brake drum or problems with the brake pad and rotor installation.
How do I keep my rims clean?
Rinse wheels to remove loose dirt and brake dust. Be sure to deliver a strong stream of water. Spray one wheel at a time with an alloy wheel cleaner. Choose a cleaner that is non-acidic to protect the wheels’ finish.
Why are only my front rims dirty?
The front wheels do more braking than the rear due to the weight transfer to the front wheels under braking. This means the brakes are larger and produce more dust, so that makes the front wheels get dirty faster than the rear ones.
