It is possible to remove rust from rims by carefully using a steel wool pad or a wire brush. When using these products, it is vital to ensure that not too much force and power is used as it can leave unsightly scratches or indents on the rims.
First, remove as much rust as possible using mild soap and water. If the soap and water does not remove the rust, and then wipe the rims down completely with rubbing alcohol. After letting the alcohol dry, a wire brush or steel wool pad can be used to scrape off the rust.
