A microwave, or microwave oven, heats food via electromagnetic radiation (microwave frequency). Microwaves typically feature a turntable that moves the food around to ensure an even heat. The heat process of the microwave is the movement of water molecules back and forth to produce thermal energy.

A recommended way of cleaning a microwave is with white vinegar. The vinegar and water, when heated, work to loosen up the food stains inside the microwave. Other tools needed for this process include: water, a bowl to hold the vinegar, a cloth, and a wooden spoon. Pour one cup of vinegar and one cup of water into a bowl and place it in the microwave with the wooden spoon in the mixture. Turn the microwave on for about 5 minutes and remove the bowl. Use the cloth to clean down the inside.
