How to Clean Alloy Wheels (and Get Brake Dust Off)
To clean alloy wheels, start with cool wheels before you wash the rest of the car. Rinse them, spray on a dedicated wheel cleaner, leave it a couple of minutes to break down brake dust and grime, agitate with a wheel brush, then rinse thoroughly. Every so often, use an iron fallout remover to dissolve the embedded brake dust that normal cleaning leaves behind.
Alloy wheels are usually the dirtiest part of any car. Brake dust, road grime and, in winter, road salt all pile onto them every time you drive. Leave it long enough and the wheels go from shiny to dull grey. The good news is that clean wheels are mostly about using the right product in the right order, not about scrubbing harder.
Why brake dust is so hard to get off
Every time you brake, the pads and discs wear a tiny amount. That wear comes off as fine dust, and a lot of it ends up on your wheels. Brake dust contains iron particles that are hot when they land, and they can bond to the wheel surface. Mixed with road grime and water, it forms a stubborn film that plain shampoo struggles to shift.
That is why wheels need two kinds of cleaning:
- Regular cleaning to remove the loose brake dust, grime and road salt at every wash.
- Periodic decontamination to dissolve the iron particles that have bonded to the surface and will not come off with a normal clean.
Clean your wheels first
Always do the wheels before the bodywork. Cleaning wheels throws dirty water and brake dust around, and you do not want that landing on panels you have just washed. Doing them first also means you are not dragging wheel grime into your shampoo bucket.
Use a separate bucket, brushes and cloths for the wheels if you can. Brake dust is gritty, and you never want it going anywhere near your paint.
Make sure the wheels are cool
Do not clean wheels straight after a drive. Hot wheels and brakes make cleaning products dry far faster than they should, which can leave marks and stop the product doing its job. Give the car time to cool down, and wash out of direct sunlight where you can. Touch the wheel with the back of your hand. If it feels warm, wait.
How to clean alloy wheels at home: step by step
- Rinse the wheels. Give each wheel a thorough rinse with a pressure washer or hose to knock off loose dirt. Get into the barrel and around the brake caliper too.
- Apply a wheel cleaner. Spray a ready-to-use wheel cleaner such as Vampire wheel cleaning gel over the face of the wheel and into the barrel. It is a thick alkaline gel, so it clings to the wheel rather than running straight off.
- Let it dwell. Leave it for 2 to 3 minutes. In that time it emulsifies dirt, grime, brake dust and road salt, so they let go of the surface. Do not let it dry on the wheel.
- Agitate with a wheel brush. Work a soft wheel brush over the face, between the spokes, into the barrel and around the wheel nuts. With Vampire, this foams the gel up and lifts the loosened dirt.
- Rinse thoroughly. Rinse the whole wheel, including the barrel and the gaps around the nuts, until there is no product left.
- Repeat on the next wheel. Work one wheel at a time so the product never sits long enough to dry.
- Finish the tyres. Once the wheels and tyres are clean and dry, dress the tyres (more on that below).
Vampire is safe on most wheel finishes and suits regular maintenance cleaning. If your wheels have a sensitive finish, such as polished, chrome or bare metal, test it on a small area first.
Best wheel cleaner for brake dust that won't shift
If your wheels still look dull after a proper clean, or feel rough to the touch, the culprit is usually embedded iron from brake dust. A regular wheel cleaner removes the loose stuff. An iron fallout remover goes after the particles that have bonded on.
Vulture iron fallout remover is a high-strength, super-cling, pH-balanced formula that dissolves embedded iron particles from brake dust, rail dust and industrial fallout. You can see it working, as it turns purple when it reacts with the iron.
How to use a fallout remover on wheels
- Clean the wheels first so the fallout remover can reach the contamination.
- Spray it over the wheel and let it react. Watch for the purple colour change.
- Agitate any stubborn areas with a wheel brush.
- Rinse thoroughly before it dries.
Fallout remover is a periodic deep clean, not something for every wash. Use it when the wheels need it, for example when you are preparing them for protection or after a long run of winter driving. It is not recommended for frequent use on ceramic coatings.
Why you should avoid household chemicals on alloy wheels
You will see all sorts of kitchen-cupboard hacks for cleaning wheels. It is best to steer clear of them. Household and industrial cleaners are not made for automotive finishes. Some are far too harsh and can stain or damage the lacquer or paint on your wheels. Others leave oily residues that attract more dirt, or can end up on your brake discs and pads, which is the last place you want anything slippery.
A dedicated wheel cleaner is designed to break down brake dust and road grime while being safe on wheel finishes when used as directed. It is the safer and simpler choice.
How to make your tyres look black again
Clean wheels next to faded grey tyres still look unfinished. Once the tyres are clean and completely dry, apply a dressing. Bigfoot tyre and trim gel is a thick gel with UV blockers and waterproofing agents. One coat gives a satin finish, and a second coat takes it glossier, so you control the look.
Apply it with an applicator or a tyre shine applicator brush, working it evenly over the sidewall. Keep it on the rubber and off the wheel face.

How often should you clean alloy wheels?
Clean your wheels every time you wash the car. Brake dust is easier to remove when it has not had weeks to build up and bake on. In winter, when road salt is added to the mix, regular cleaning matters even more. Save the fallout remover for a periodic deep clean when the wheels need it.
Alloy wheel cleaning FAQs
Can I clean alloy wheels with car shampoo?
Shampoo will remove light dirt, but it struggles with bonded brake dust. A dedicated wheel cleaner does the job far more easily.
How do you get baked-on brake dust off alloy wheels?
Clean the wheels with a wheel cleaner, then use an iron fallout remover to dissolve the embedded iron. Agitate stubborn areas and rinse before it dries.
Why does my fallout remover turn purple?
The colour change shows the product reacting with iron particles. Vulture turns purple as it dissolves them.
Should I clean wheels before or after washing the car?
Before. Wheels are the dirtiest part of the car, and cleaning them first stops grime splashing onto freshly washed panels.
Can I clean my wheels when they're hot?
No. Let them cool first. Hot wheels make products dry too quickly, which can leave marks and stop them working properly.
