How to Remove Rust From Alloy Wheelsby Justin Obrien
Technically speaking, alloy wheels don't actually rust. They do have the ability to corrode, but it is not quite like rusting. Instead of the brownish orange rust color, you get white stains. Most stock alloy wheels are polished and have a protective finish that is designed to prevent corrosion. Sometimes corrosion will get through and allow the alloy to get damaged. All is not lost; you can remove the rust from your alloy wheels and get them looking like new again.
Purchase a rust remover product that is safe to be used on alloy. Read the container for safety precautions and to make sure that it is made to work well with alloy.
Apply the remover product follow the manufacturer's instructions. You should also allow it to sit on the rusted areas for the recommended amount of time before proceeding.
Scrub the rusted areas with the nylon scrubber first. In many cases, this will be enough to remove the spots. If it works, skip to Step 5. If there is still stubborn rust spots, continue with the next step. Keep in mind that you are not looking for typical rust on your alloy wheels. You're seeking a white-ish color that signifies a type of corrosion.
Scrub the rusted areas with the steel wool scrubber. Keep scrubbing the areas until the spots disappear and are smooth. Make sure that you are getting in all of the spots around the lug nuts and any holes that are in the middle. Do not scrub too hard with the steel wool; alloy is a softer metal, and you can actually cause deep scratches if you apply to much pressure.
Rinse the wheels with water to remove the debris.
Use the soap, sponge and water to clean the wheels. If you notice smaller spots of white rust on your alloy wheels, you may need to use a wheel cleaner.
Rinse the wheels again. Allow them to dry.
Apply an alloy wheel polish, such as Mother's Wax.
