Mix one-half cup white vinegar and one-half cup water in a microwave-safe bowl. For a very dirty microwave, use one cup vinegar and one cup water for a deeper clean.
Place the bowl in the microwave, and heat it on high for five to 10 minutes. As the liquid heats, it creates steam, which loosens the grime in the microwave. Let the bowl sit in the microwave for a couple of minutes after the time is up to let the steam continue to build.
Carefully remove the bowl from the microwave using oven mitts or a dish towel if the bowl is hot. Use a sponge or rag to wipe all the surfaces clean, dipping the sponge in the remaining vinegar mixture if needed.
