While doing some scratch repair on my blue Special with Meguiar's M105 Ultra Cut Compound, I hit the rubber around the windows and the gray plastic for the Special ground effects. Each now seems to have a white haze that nothing seems to remove. I've tried Back to Black Heavy Duty Trim Cleaner, a tooth brush with Dawn, and alcohol all to no avail. Also tried Back to Black and Addams VRT. While they make the rubber look better, the white spots remain. Any ideas?
Try some wax and grease remover, a product body shops use to remove all traces of wax, grease and silicone before paint work. Try it in an inconspicuous spot first to make sure it doesn't hurt the surface, and only on the areas that need the compound removed. You will probably have to treat the cleaned areas with some 303 Penetrant or similar product to restore the original look.
