Do not allow plasticobjects, sugar, or foods with high sugarcontent to melt onto the hot cooktop. Melted materials can cause permanent damage to the cooktop. If you accidentally melt anything onto the cooktop, remove it immediately while the cooktop is still hot. Carefully, use a single edge razor blade held with a pot holder to remove melted on material. Do not use aluminum foil or foil-type containers under any circumstances. Aluminum foil will damage the cooktop if it melts onto the glass. If metal melts on cooktop, do not use. Call an authorized Jenn-Air Service Contractor. Do not use the glass-ceramic cooktop as a cutting board. Do NOT use abrasive cleansing powders or scouring pads (including metal scouring pads), which will scratch the cooktop. DoNOT use chlorine bleach, ammonia, rust removers, oven cleaners, or other cleanser not specifically recommended for use on glass-ceramic. Never immerse your cooktop cartridge in water. Test cast ironware since all are not flat. Also be cautioned against possible "impact damage" should the heavy cookpot be dropped on the glass-ceramic surface.
