Glass or ceramic stovetops are attractive and easy to clean up when minor spills happen, but they need to be cared for properly. Over time and after frequent use, a glass stove will become dull, creating a cloudy appearance on the burner areas. This is because liquids and foods spill over and soap residue from the bottoms of pans end up on the burner. Once you turn on the, the spills and residue bake onto the surface. You can remove cloudy spots by cleaning the stovetop properly.
Use a new razor blade to scrape any solid burned food or especially dark stains. Scrape at a 45-degree angle to avoid damaging the surface.
Wipe away the scraped-off pieces of food with a paper towel.
Apply a quarter-sized amount of ceramic stove top cleanser to the center of the stove top. Rub it in and wipe it around with a paper towel. Allow it to dry until it leaves a grayish haze over the entire surface.
Buff the haze off of the surface with a paper towel. You may need to apply pressure and buff the surface to a shine.
