36_ Maintaining your appliance
Removing heavy, burned-on residue
1. Allow the cooktop to cool.
2. Use the single-edge razor-blade scraper at approximately a 45° angle against the glass surface
and scrape the soil. It will be necessary to apply pressure in order to remove the residue.
3. After scraping with the razor scraper, spread a few drops of ceramic cooktop cleaner on the
entire burned residue area. Use the cleaning pad to remove any remaining residue. (Do not
scrape the seal.)
4. For additional protection, after all residue has been removed, polish the entire surface with the
cooktop cleaner and a paper towel.
Removing metal marks and scratches
1. Be careful not to slide pots and pans across your cooktop. It will leave marks on the cooktop
surface. You can remove these marks by applying ceramic cooktop cleaner.
2. If pots with a thin overlay of aluminum or copper are allowed to boil dry, the overlay may leave
black discoloration on the cooktop. You should remove this discoloration immediately or it may
become permanent.
Carefully check the bottoms of pans for roughness that may scratch the cooktop.
Cleaning the cooktop seal
To clean the seal around the edges of the glass, lay a wet cloth on it for a few minutes, then wipe
clean with a nonabrasive cleaner.
Potential for permanent damage to the glass surface
Sugary spillovers (such as jellies, fudge, candy, syrups) or melted plastics can cause pitting •
of the surface of your cooktop. This is not covered under the warranty. You should clean the
spill while it is still hot. Take special care when removing hot substances. Refer to the following
section.
When using a scraper, be sure it is new and the razor blade is still sharp; do not use a dull or •
nicked blade.
Cleaning sugary spills and melted plastic
1. Turn off all surface units. Remove hot pans.
2. Wearing an oven mitt, use a single-edge razor-blade scraper to move the spill to a cool area of
the cooktop. Remove the spill with paper towels.
3. Any remaining spillover should be left until the surface of the cooktop has cooled.
4. Don’t use the surface units again until all of the residue has been completely removed.
If pitting or indentation in the glass surface has already occurred, the cooktop glass will
have to be replaced. In this case, service will be necessary.
