What is Brake Dust?
Brake dust is caused by the abrasion between the brake discs and pads. It doesn't necessarily mean something is wrong with the brakes and it is more of a cosmetic issue than anything else. However, if left untreated for a long period of time it can damage the alloy due to its corrosive properties. There are some simple steps you can take to prevent the dust from causing any damage.
How to clean brake dust?
If you've washed the alloys and the dust still remains then it's time to up the game to
wheel cleaners. They are designed to remove even the most stubborn dust but make sure to read the label first, some are designed to work only on specific metals and alloys. Begin by applying the cleaner to the alloy wheel and use a good quality alloy or nylon brush to work it well into the dust. After the dust has been lifted, wash it away with plenty of water. You may need to move the car slightly to ensure that you can clean every part of your alloys.
How to prevent brake dust build up?
Regularly washing your wheels is the first step to prevent the dust accumulating or causing any serious damage. Pay close attention to crevices or angles in the alloy wheels where the dust tends to build up. Using purpose made brushes such as
Meguiars™ Versa Angle Brush can be great to clean those awkward angles. After cleaning, apply a layer of alloy wheel wax to protect the shine and prevent the dust from making direct contact with the alloy in the future. The next time you wash the alloys the brake dust should come off a lot easier. Re-apply wax every 2-3 months depending on how often you drive and always make sure to clean the alloys before applying the wax.
