To clean a burnt microwave oven, use a washcloth, a bowl of warm water and a clean dry towel. Fill a bowl with warm water, soak the washcloth, open the microwave and begin scrubbing the inside with a wet washcloth, follow with a clean, dry towel as explained by a chef in this free video on cleaning.
Hi, I'm Pete Dryden, and I am going to show you how to clean a burnt microwave oven. Things you will need: a microwave, a washcloth, a bowl of warm water, and a clean dry towel. The first step is to fill a bowl with warm water. Now, soak your washcloth in warm water. Open the microwave door and begin scrubbing the inside of your microwave with your washcloth. You can usually use your finger nail through the wash cloth to remove most hard to clean spots. Now, take a clean towel and dry the inside of your microwave. Now, shut the door and you've got a microwave that's good as new. And that is how you clean a burnt microwave oven.
