Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and optimal performance of your microwave oven.

- Door Seals: Keep the door seals and sealing surfaces clean. Do not use harsh detergents or abrasive cleaners.
- Turntable: The glass turntable and turntable ring can be removed and washed in warm, soapy water or in the dishwasher. Ensure they are completely dry before placing them back in the oven.
- Odor Removal: To remove odors, combine 1 cup of water with several tablespoons of lemon juice or vinegar in a microwave-safe bowl. Microwave on high for 5-7 minutes.
CAUTION: Always unplug the microwave oven before cleaning. Do not immerse the appliance in water or other liquids.
