A: There is nothing more frustrating! The abrasives in the wax have become trapped within the pores of the rubber so the only way of removing it would be to re-dissolve the wax in a solvent like mineral spirits or kerosene (can be found at any Home Depot). A little rubbing alcohol can also be used. In the future, try Armor All® Wax-it-Dry® gel (doesn't contain abrasives, no white residue) because when used on a wet surface, it won't stain your rubber and plastic areas.
