You wash, polish, and wax your car. You take it for its annual MOT and you vacuum it every weekend. But how about the wheels and rims? It’s important to clean your car’s alloy on the wheels and rims because these are the parts of your car that are the most prone to getting dirty. Learn how to clean your alloy wheels with a little help from WD-40…

The dirt on car rims is mostly a black powder that has come from the surface disintegration of the brake pads. Every time you brake, the brake pads connect with the rotating discs and create debris. You may also find a layer of greasy material on the rims, this can come from oils from the engines, transmission systems of cars on the road, and suspended in the exhausts. These greasy materials can mix with water to form emulsions, which, when dry, is very difficult to remove.

How to clean alloy wheels with WD-40

To keep the rims of your car clean, regardless of whether they are made of steel, alloy or other materials, they must be cleaned weekly to eliminate all of the deposits mentioned.


The mud, dust, and powder from the brake pads can be removed with a pre-wash using a pressure washer. Then, apply a good car wash cleaning product mixed with water to the rim using a spray bottle or brush. Leave it to soak for a few minutes and then spray again. Next, use the brush to remove the dirt.

Remove the stubborn dirt

The pre-wash will have removed the excess dirt and debris, but the grease stains and oily deposits will still linger. This type of dirt should be treated differently. After washing with detergent and rinsing off, apply WD-40® Multi-Use Product on a cloth and rub in the product in affected areas. It is a formula that helps to remove grease, oil, and dirt without leaving any residue. It acts immediately on contact and is easy to rinse off. You must be extremely careful, however, that the product does not go into the brake pads. It is best to apply it by spraying the product onto a clean cloth and then passing the cloth over the rim and alloys.

The product has a Smart Straw applicator which lets you switch from a large spray to a precise applicator in one simple move. After applying, pass a clean rag over the treated parts, spreading the product over the entire surface of the rim, or you can repeat the final washing with another dose of detergent.
