How to Clean Your Microwave

Step 1: Fill a microwave-safe bowl with one cup of water and 1/4-cup of white vinegar. If you don’t have vinegar handy, you can substitute one teaspoon of dish soap.

Step 2: Put the solution in your microwave and cook it for approximately one to two minutes (this depends on what wattage you’re using). For example, if you have a 1,200-watt or higher microwave, between one and one-and-a-half minutes should suffice. If you only have a 700-watt microwave, you may need to cook the solution for two minutes or longer if necessary. The goal is to steam the solution without having it boil over or spill out of the container. Microwaving first lets the steam do most of the work for you.

Step 3: After the time is up, make sure to keep the door closed for three minutes or so. This will allow the steam to heat the bottom, sides, and top of your microwave.

Step 4: Once you’ve waited three minutes, carefully remove the bowl from the microwave. Be sure to use a potholder to avoid getting burned.

Step 5: Wipe the sides of your microwave with a paper towel or washcloth. You may need to use a heavy-duty sponge to scrub off any stubborn food stains. We recommend not using Clorox wipes.

Step 6: Take out the rotating plate and wash it with soap and water in your kitchen sink. You can also put the plate in the dishwasher if that works better for you.

Step 7: Take a damp paper towel or washcloth and add soap or a disinfectant. Use this to wipe down the exterior and control panel. Keep the cleaner away from the vents by not spraying it onto the microwave. Spray it onto the paper towel or washcloth first.

Step 8: If you have a seal or gasket on your microwave, you can use the wet paper towel or cloth to clean it. Make sure to wipe down the roller wheel as well. Take a dry paper towel and wipe off any soap residue left on the inside of the microwave.

Step 9: Once you’re finished cleaning the roller wheels and the rotating plate, place them back into the microwave.

Step 10: Now, you can use your impeccable microwave to cook whatever you need.
