Care and Cleaning of Your Microwave Oven
Inside of the oven: Wipe with a damp cloth after using. Mild detergent may be used if needed. Do not use harsh detergents or abrasives.
Oven Door: Wipe with a soft dry cloth when steam accumulates inside or around the outside of the oven door. During cooking, especially under high humidity conditions, steam is given off from the food. (Some steam will condense on cooler surfaces, such as the oven door. This is normal.) Inside surface is covered with a heat and vapor barrier film. Do not remove.
Roller Ring and oven cavity floor: Clean the bottom surface of the oven with mild detergent water or window cleaner, and dry. Roller Ring may be washed in mild soapy water or dishwasher. These areas should be kept clean to avoid excessive noise.
Control Panel: Covered with a removable protective film to prevent scratches during shipping. Small bubbles may appear under this film. (Hint – To remove film, apply masking or clear tape to an exposed corner and pull gently.) If the Control Panel becomes wet, clean it with a soft dry cloth. Do not use harsh detergents or abrasives.
Outside oven surfaces: Clean with a damp cloth. To prevent damage to the operating parts inside the oven, water should not be allowed to seep into ventilation openings.
