A glass cooktop scratches from abrasives, dragged particles, and incorrectly used tools. The safest cleaning starts when the surface is at the manufacturer-approved temperature, removes loose debris first, and uses approved cleaner and scraper techniques without unnecessary pressure.
Let the surface cool unless the manufacturer says otherwise
Most routine cleaning is done with the cooktop cool to prevent burns and cleaner from baking onto the glass. Melted sugar spills may have special instructions, so follow the manual for that specific situation.
Remove grit before wiping
Salt, sand, and hard crumbs can act like sandpaper when dragged under a sponge. Lift them with a soft damp cloth and switch to a clean area of the cloth as particles are collected.
Use nonabrasive cleaner and an approved scraper angle
Use a small amount of the recommended cleaner. If a blade scraper is approved for stuck residue, hold it at the specified shallow angle and slide it without digging in a corner or using it on damaged glass.
Avoid steel wool, abrasive powders, and dirty cookware bottoms
After cleaning, dry the cooktop and keep pan bottoms clean before cooking. A deep scratch, crack, or chip cannot be safely polished away at home; stop using a damaged area and follow manufacturer guidance.
