Best products to clean alloy wheels.
Meguiar’s Ultimate All Wheel Cleaner is the product I recommend for use on wheels for removing brake dust.
The Wheel Cleaner products below all contain the same key ingredient. It has one goal and that is to dissolve iron particles.
There are two types of sprays. One type is designed for wheels only and the other is for use all over the car.
CarPro Iron-X is something that can be sprayed all over your car – not just the wheels. But it’s not as strong as Meguiars.
If I have time on my hands I like to completely remove the wheels from my car so that I can clean inside the rims. But maybe that’s going a bit too far for most people.
Why are rims so hard to clean?
Brake dust is formed as your brake discs wear away. Some cars generate more than others and also it depends on your driving style and distance covered etc.
Brake dust can be very difficult to wash off with regular car shampoo.
Brake dust can actually burn into your rims and cause permanent discoloration. So if the appearance of your car is important to you then you need to wash it away regularly.
Brake dust also bonds to your paint. As you wash and dry your paint it will become loose and cause the paint to lose some of its shine.
Reasons to keep your wheels looking good
- Wheels can be a very expensive part of your car. When you go to sell your car it can have a negative effect on your car’s value if you have damaged wheels keeping them clean pays off.
- Brake dust can bond to your wheels in a few days. So if you can’t wash your wheels every day (not many people can) you will need a product that will loosen the dust so you can easily wash it away.
- The longer to go between washes, the worse the problem will get. So wash your wheels regularly and use a dedicated wheel cleaner every now and then.
Meguiar’s Ultimate All-Wheel Cleaner Review
A wheel cleaner sprays like this one from Megs can be used on many types of wheels. Painted or chrome wheels can be safely cleaned. That’s because it doesn’t contain acid. It’s also safe on brakes and calipers.
So if you have brightly colored brake calipers it’s perfect.
It goes on clear and reacts with bonded brake dust and changes color. It becomes purple which is a sign that it’s working.
It has a nice gel-like consistency so it sticks to the wheel and doesn’t run very much.
It works best on a cool and dry wheel. A wet wheel dilutes the product and reduces its effectiveness. Meguiars Ultimate All Wheel Cleaner doesn’t just remove brake dust. It also breaks down oily residue from the road to make cleaning much faster.
This set from a 3-piece kit from ABN is perfect. These soft brushes don’t splash dirt back at you either.
I will just agitate the product and move it around the spokes a little to get it into all the hard-to-reach spots. There is no need to scrub the product. It just needs time to react with brake dust to do its magic.
I will use a normal tire brush to clean the tires and then use the pressure wash to black the dirt away. Perfect job every time.
Another thing to note is that I prefer to do my wheels first when I’m washing my car. This way it doesn’t matter if I splash the paint. The wheels are often the dirtiest part of the car.
How often should I use Meguiars Ultimate All-Wheel Cleaner?
I only use it when my wheels clearly need it. Which is probably once a month. Usually, I will just use regular car soap like Meguiar’s Wash and Wax. I use a special microfiber wash mitt just for the wheels. This mitt will never be used to wash the car’s paint because brake dust will scratch paint.
If I am only giving my car a quick clean to remove light dust will just use some quick detail spray like Adams Detail Spray along with a microfiber cloth to remove the light dust. Again this microfiber cloth is just for wheels.
Can you clean wheels with a clay bar?
Yes, you can clean wheels with a clay bar. But first, you should use a wheel cleaner spray to remove as much iron as possible.
And if your wheels still feel rough to the touch, use a clay bar with a detailer spray or with a dedicated clay luber.
My Wheel Cleaning Tips
- Spray the product onto a dry wheel.
- Let it work for a few minutes (read label).
- Don’t scrub with a hard brush.
- Don’t let it dry as it can stain.
- Agitate with a soft brush if required.
- Power wash off.
- If it doesn’t work the first time, try again.
- For heavily stained wheels you may need to apply the products a number of times
- Its worth repeating, don’t scrub.
- A pressure washer is a safe way to clean wheels.
- A clay bar can be used after a wheel cleaner.
- Dry with a microfiber towel.
- Apply a spray sealant and buff off.
CarPro Iron-X Review
I have used Carpro Iron-X for years. It’s something I would use maybe once a year on my car’s paint and glass as well as wheels. It helps to remove brake dust from your entire car.
I use Iron-X when I plan on applying a new layer of sealant or wax. Maybe I want to remove some scratches or just restore my car’s shine using the polisher if it has begun to fade. If I’m going to use a clay bar I will do it after using Iron-x.
Iron-X removes the iron particles and rail dust that could become loose during polishing or buffing and could scratch the paint.
Sealant and wax will bond much better to the paint and the shine will look deeper and last much longer.
The product is sprayed onto the car and rubbed in with a damp microfibre sponge. It’s best not to let the product dry so do it on a cool evening or in the shade. It will turn purple as it works its magic. Then I blast it away with the power washer. It’s a really quick process.
The car immediately looks much cleaner. Especially a white car. You will notice bugs have also been removed. Also, emblems and badges will look much cleaner. Had to clean areas around door handles will be spotless. This is a fantastic product and it’s one of the products I would never be without.
It also works well on wheels. But for really dirty wheels I would use Meguiars Ultimate Wheel Cleaner as it seem to be much stronger.
You can now proceed to your next step such as, polishing, sealing or waxing.
Protecting rims from brake dust damage.
In the past I have put spray wax on my rims to shine and protect them. But it doesn’t bond very well and doesn’t last. So I recently started using another Sonax product called Sonax Spray and Seal on my car and wheels. It’s a spray sealant and it’s super easy to apply.
You just spray it on after a wash. Then rinse again and dry with a microfiber cloth. It gives great protection but the main reason I love it is that it’s so very easy and quick to use. You can also use it on paint, plastic and rubber. I find that my wheels keep their shine a lot longer and brake dust is easier to wash off on the next wash.

Meguiars Ultimate All-Wheel Cleaner is an excellent product. It’s very fast and very effective. It cost a little more the some other wheel cleaners but I think it’s worth it. And it’s excellent value if you buy it in larger quantities.
Carpro Iron X is an amazing product too but is even more expensive. It’s great for removing iron contaminants from your entire car which will help wax and sealant to give a better bond.
It can also clean your wheels. Any car detailing fan or professional will have both of these products in the arsenal. I know I do.
