Be sure that the appliance is turned off and parts are cool before cleaning. Clean after each use to prevent staining. When spills occur, turn off cooktop, allow to cool, and
wipe with a soapy cloth or paper towel. NOTE: Remove sugar and acidic spills immediately when cool as they deteriorate the enamel on grates and burner caps. Do not use
excessive moisture or spray cleaners when cleaning around knobs.
