Clean a ceramic-glass cooktop without abrasives or scratches
Check power and residual heat, use nonabrasive cleaners and only use a scraper when the model manual permits it.
Cooktops that look alike may have different surface coatings. Whirlpool and SCHOTT CERAN recommend nonabrasive methods and, for compatible ceramic-glass surfaces, appropriate cleaners and scrapers. Some special-coated surfaces can be damaged by a scraper, so always check the exact model.
