Bleach is great for cleaning up messes around the house, but it can keep your hubcaps shiny, too. If your rims are looking worse-for-wear, KiwiReport recommends sprinkling a little bleach powder on them. Then, add a splash of Lysol and start scrubbing with the help of a steel wool brush. With a little bit of elbow grease and dedication, your rims will look like they just drove off the assembly line.
