Using this Panasonic glass plate is easy. Just place it in your microwave, making sure it sits properly on the turntable. When you're done using the microwave, wait for the plate to cool down before removing it. To clean, use warm, soapy water and a soft sponge. Avoid using abrasive cleaners as they can scratch the glass. Also, don't expose the plate to sudden temperature changes, like putting a hot plate under cold water. This can cause the glass to crack. If you notice any chips or cracks in the plate, stop using it right away and replace it. With proper care, this glass plate will serve you well for a long time.
