Vinegar and water To clean the microwave with vinegar, fill a microwave-safe container with two cups of water and two tablespoons of vinegar. To minimize the smell of vinegar, you can add two drops of your favorite essential oil. The good news is that most of the same cleaning products that you already have in your arsenal are often used to clean tough stains from a microwave. Now that you have a clean microwave, make sure to keep it that way by cleaning up spills and splashes as soon as they occur.
Either way, make sure you put the cleaning agent of your choice directly onto a sponge, clean cloth, or paper towel so it doesn't drip deep into the microwave. If you don't clean it soon after heating the food, it hardens and becomes much harder to clean.
