how can i check stubborn marks on ceramic or induction cooktop glass?
a mark that appears to be beneath cooktop glass may be a deposit on its surface. check intact ceramic or induction glass gently; a crack, chip or lifted coating is damage, not something to scrape away.
model scope: ceramic and induction glass surfaces.
turn the cooktop off and let it cool, then use the cleaner approved for the particular glass or coating with a soft cloth. specialist coatings and hot sugar spills need their own manual instructions rather than a general cleaning method.
for stubborn residue, the linked glass-care guide permits a purpose-made cooktop scraper only where the exact manual allows it. do not use a loose razor blade, press on a suspect area or remove the cooktop to investigate the mark.
if you cannot distinguish residue from damage, stop cleaning and leave the surface out of use until assessed. cracked glass also requires power isolation if safe. cleaning cannot repair a crack or restore a damaged coating.
possible causes
- residue sitting on the glass
- a spill cooked onto the surface
- damage to the glass or its coating
