I use my microwave oven several times a day. It’s a great convenience. However, cleaning out the inside of a microwave oven can be a real pain, especially if something blew up inside and dried out bits of food are stuck to the oven walls. Cleaning up a mess like that can be a real chore; however, here’s how you can easily clean up that mess in 30 seconds or less. Put a bowl of water with some lemon juice in it in your microwave oven and cook it at full power for 3 to 5 minutes. The steam with soften the crud inside your microwave oven. You can then clean out the inside of your microwave oven with a damp sponge in 30 seconds or less!
