Remove badge from lid by prying those little nuts off with a razor blade or small flat head screwdriver. Spray some brake cleaner on the badge and wipe it down. Spray the badge with hi heat ultra and let dry for at least a few hours. Set a piece of sandpaper on a flat board and start rubbing the badge to remove the paint from the border. If you want the aluminum border to be shiny, use finer grit sandpaper after all the paint is removed. Reinstall badge with the original nuts or buy new ones at Ace hardware.
