water or in a dishwasher. If grease
accumulates, clean with a non-
abrasive nylon mesh scouring pad
and a non-abrasive cleanser.

damp cloth. To prevent
damage to the operating
parts inside the oven,

allowed to seep into
ventilation openings.

microwave leakage.

detergent water or window cleaner and dry.

water or dishwasher. These areas should be
kept clean to avoid excessive noise and
