Schott Ceran is a German maker of glass-ceramic cooktops that don't utilize toxic chemicals in the manufacturing process, such as arsenic and antimony. As with other brands of ceramic cooktops, Schott Ceran products are susceptible to scratches and damage from melted plastic, improper use and accidents. If your eco-friendly cooktop has suffered this fate, don't assume the product needs to be replaced. It's possible to remove the burnt-on plastic, scratches, chips and minor cracks without calling in a professional.
Melted Plastic and Burnt-On Food
Allow the cooktop to cool completely then spread a thin amount of cream ceramic cooktop cleaner on the burnt-on food or melted plastic.
Remove the unwanted burnt-on food or plastic by scraping it away with a utility knife. Hold the blade at a 30- to 45-degree angle and scrape off the material. Add more cream ceramic cooktop cleaner to the cooktop surface as you remove the original application.
Dampen a soft towel with water and wipe away the remaining cream ceramic cleaner once the burnt-on food or melted plastic is gone.
Scratches, Chips and Minor Cracks
Clean the damaged area with a damp kitchen sponge and cream ceramic cooktop cleaner. Work the product into the affected area and around it to remove any dirt, grime or grease. Wipe away the cream cleaner with another damp kitchen sponge.
Dry the area with a soft cloth. Fold a piece of fine-grit sandpaper then buff it over the scratch or inside the minor chip or crack to remove any fine pieces of glass.
Mask the area around the scratch, chip or minor crack with painter's tape. This protects the undamaged portions of the cooktop from exposure to the enamel repair product.
Put on a pair of rubber gloves then mix the ceramic cooktop repair compound according to the package directions. The repair compound typically consists of a hardener and paste filler.
Apply a small amount of the repair compound to the affected area with a small paintbrush. Work the compound into the crack or chip with a toothpick. Allow the repair compound to dry for at least eight hours.
Remove the excess filler/hardener from the area around the repair with a cotton swab soaked in denatured alcohol.
Cover the area adjacent to the repair, including the cooktop and knobs, with painter's tape and butcher paper.
Shake the can of enamel spray, which is also part of the repair kit, for at least 30 seconds to one minute. Hold the spray can approximately 6 inches away from the repair area and apply the product with even back and forth motions.
Allow the paint to dry for at least 24 to 48 hours before removing the butcher paper and painter's tape.
