If you're at all like me, you use a microwave for almost every meal (pizza rolls, anyone?), and this cleaning hack will remove all excess food stains from your microwave. Mix one cup of water with one teaspoon of dishwashing detergent in a measuring cup and microwave the cup for four minutes. The steam from the mixture will soften all the baked on food, which makes it easy to wipe all the grime from the microwave.
