Cleaning a microwave can be a little tricky. You cook food in there and you don’t want to use harsh chemicals to wipe it out! One way is to use warm soap and water with a sponge. Another way to clean a microwave is to put a couple of tablespoons of vinegar in a bowl. Microwave on high for 45 seconds to 1 minute (time depends on your particular model). Carefully take the bowl out and wipe out the oven.
