Prepare to buff the stovetop by cleaning the glass surface with appliance or window cleaner and a soft rag or paper towels. The stovetop should be cleaned immediately after every use or spill. Almost any cooked-on spill that is not easily removed with window-cleaning solution can be scraped off with a razor scraper after the hardened spill has been softened with cleaning solution.
Apply the glass-buffing preparation to the stovetop as instructed by the manufacturer. Liquid polishes typically must be shaken before application; paste-type suspensions do not. Allow time for the buffing preparation to dry to a chalky film.
Buff the stovetop with a soft rag. Use moderate pressure and buff in small circles. Removing the scuffs or scratches from the stovetop requires friction provided by vigorous buffing. After the stovetop has been buffed, wipe away any residual polish with a clean rag.
Rub or gently glide your fingers across the stovetop. If a scratch on the stovetop is especially deep, you may need to repeat the buffing process in that area. The buffing compound does not fill in the scratch. It smoothes the stovetop by grinding down or sanding the irregularities in the cooking surface, making the scratches less noticeable and less prone to trap debris.
