Using this Westinghouse microwave glass plate is easy. Just place it inside your microwave oven on the turntable. Make sure it sits flat and centered for proper rotation. When using, avoid placing extremely hot or cold items directly on the glass as it may cause cracking. Also, don't use abrasive cleaners on the plate. For regular cleaning, use a mild dish soap and a soft sponge. Rinse it thoroughly and dry it with a clean cloth. Store the plate in a dry place when not in use to prevent any damage. If you notice any chips or cracks, stop using the plate immediately and replace it to ensure safety.
