Information about Cleaning Ceramic Coatings
Repeated washings in a dishwasher will cause the nonstick properties of the ceramic coating to slowly diminish. In addition, the bottom of the skillet or griddle will likely discolor due to the caustic nature of the dishwasher detergent and a gray residue may form on the bottom of the skillet or griddle. This residue may transfer onto towels and/or skin.
In time, the ceramic nonstick finish may darken over the heating element. To minimize or remove this discoloration, sprinkle baking soda over the discolored area. Add enough water to make a paste. Allow paste to sit for several minutes and then scour with a plastic scouring pad, such as Scotch-Brite* Dobie* Cleaning Pad, or a damp cloth. Wash and dry thoroughly. Repeat the procedure, if necessary.
