Homes & Gardens' glass-stove guide warns against rough tools and excessive pressure. Strong general glass cleaners may also be unsuitable for a cooking surface, making the appliance manufacturer's recommendations more useful than a familiar spray bottle.

Protect Glass Cooktops From Abrasive Cleaning Pressure

Let the surface cool and remove loose debris before using an approved product and soft cloth. Use a scraper only when the manual permits it and describes the correct technique. Finish by removing residue as directed so the next cooking session does not heat cleaning material left on the glass.

Removing cooking marks should not introduce scratches into the surface.
