- Spray a wheel cleaner onto dry wheels and rinse it off fully.
- Don't clean hot wheels or work in hot weather.
Brake dust is the fine dust your brakes release every time you slow down, and the heat from braking bakes it onto the wheels. Once it has been baked on, a dull, clear-coated factory wheel needs more than a quick wipe, and a plastic polish after washing is the suggested fix for that finish. Dust that has landed on the paint is a separate problem, so it gets its own treatment.
Don't scrub baked-on dust dry, or the grit will scratch a clear-coated finish. Use a brake dust cleaner on cool wheels, and let a prewash stain remover spray sit on stubborn spots before you agitate. If dust has also settled on your paint, handle that as a separate job so you don't drag grit across the wheels.

5 steps
Step by step
Step 1 of 5
Let the wheels cool first
Wait until the wheels are cool after heavy braking or a long drive before you touch them with any product. Brake dust bakes onto hot wheels, so cool wheels are the ones that clean up properly.
Careful. Don't clean the wheels while they're hot or in hot weather, because the cleaner dries before it can work.
Step 2 of 5
Wash with stronger car soap
Wash the wheels with the car soap you use on the rest of the car, mixed stronger than usual. Work it over the face, spokes and barrel, then rinse off the soap and let the wheels dry before the next step.
Step 3 of 5
Spray on the wheel cleaner
Spray the wheel cleaner evenly over each dry wheel, covering the face and spokes. Let it sit for a few minutes at most, since the label sets the exact time.
Careful. Don't leave the wheel cleaner on longer than its label says, since longer contact can cause light staining.
Step 4 of 5
Rinse the wheels thoroughly
Rinse every wheel until no cleaner is left on the face, spokes or barrel. Start at the top so the water carries the loosened dust down and away.
Careful. Rinse thoroughly so no cleaner is left to dry on the wheel.
Step 5 of 5
Dry with a microfiber towel
Dry each wheel with a clean microfiber towel, and use a fresh section of the towel for each wheel so the dust doesn't spread.
Tip. Keep one towel just for the wheels so the dust doesn't reach the paint.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:

Brake Dust on every material
No match. Try the main search for anything else.
How to tell it's working
The wheels should look free of the dark dust, and the spokes and barrel shouldn't feel gritty when you run a hand over them. If a patch of paint nearby still feels rough, that's dust bonded to the paint, and the clay treatment is the fix.
What changes for yours
Adjust for where the stain is
Paint
Brake dust that has bonded to the paint needs a detailing clay bar. Spray a mist-and-wipe spray over the area as the lubricant, then rub the clay gently across the paint.
Wipe the surface with a microfiber towel after claying, then wax the paint for longer-lasting protection. Everything else in the wheel steps stays the same.
Painted Calipers
Calipers sit right at the brakes, so wait until they're fully cool before you start. Wash them with the car soap, mixed stronger, using a soft microfiber towel. Skip the wheel cleaner unless its label says it's safe for painted calipers, because it's written for wheels.
If dust is still there after the wash, repeat the car soap wash rather than reaching for a stronger product. Let the calipers dry fully before you check them.
Old, dried or set-in stains
Old brake dust that has bonded to paint for a long time won't lift with a wash alone. Use the clay treatment from the paint card, going over the same spots more than once if needed.
Dust that has dried and hardened on the paint responds better to a few light passes than one hard push. Keep the mist-and-wipe spray generous so the clay keeps gliding and doesn't drag.
After claying, the paint should feel smooth, so wipe it down and wax it. If dust is still there, stop and wash the area again rather than rubbing harder, then check the spot.

What makes it worse
Mistakes to avoid
Don't use a rust remover on painted wheels
Rust remover is only for rust on chrome or stainless steel wheels, and it should never go on a painted or coated surface. For brake dust, it's the wrong product, and the wheel cleaner does the job.
Don't mix chlorine bleach with other cleaners
Never mix chlorine bleach with ammonia, vinegar or other cleaners. If you use more than one remover on the wheels, rinse thoroughly between them so nothing mixes on the surface.
When to call a professional
If the dust still won't come off after a proper wash, the wheel cleaner and the clay treatment, a professional detailer can check the finish and remove what's left. Ask them which products they use, so you can match them at home next time.
Questions
How do you clean brake dust stains?
Start by waiting for the wheels to cool, since hot wheels can't be cleaned well. After the car soap wash and the wheel cleaner, rinse everything off and dry it with a clean microfiber towel. Dust bonded to the paint needs a detailing clay bar instead.
What's the best cleaner for brake dust?
Use a wheel cleaner made for wheels, sprayed onto dry wheels after they've cooled. Follow its label, since it should stay on for a few minutes at most, then rinse it off thoroughly. For dust bonded to paint, a detailing clay bar is the right tool.
Will a detailing clay bar scratch my paint?
A detailing clay bar is non-abrasive and safe on any paint finish, including clear coats. Use a mist-and-wipe spray as the lubricant, and follow the kit's label.
Do painted calipers need different products than wheels?
Treat them with the same gentle car soap wash, and check the label before you use a wheel cleaner on them. Wait until they're fully cool, since they sit right at the brakes.
Why does brake dust get baked on?
Brake dust is the fine dust released by braking, and the heat from braking bakes it onto the wheels. That's why wheels that have just been driven hard are the harder ones to clean.
Can I use the wheel cleaner on my paint too?
Keep the wheel cleaner for the wheels and use a detailing clay bar on paint, since that's the tool for bonded brake dust. If you ever want to use a cleaner somewhere else, check its label first.
