How Often to Clean a Microwave

Since the microwave is such a popular appliance in the kitchen, it’s often used around the clock. As such, aim to deep-clean your microwave once per month and wipe down the exterior every time you wipe down the countertops. If you notice stains or odors accruing, then increase the frequency. “Microwaves normally have a lifespan of about five to 10 years depending on quality of care,” says Vera Peterson, a cleaning expert and president of Molly Maid, a Neighborly company. “Regular cleaning helps your microwave stay in its best working condition.”

How to Clean Microwave Filters

Countertop microwaves don’t have filters, but above-the-range microwaves with exhaust fans do. This is the vent you turn on when cooking on the stove to help with smoke and grease. Microwave filters need to be cleaned every three to six months, depending on how often they’re used. A dirty filter is a fire hazard and prevents the microwave from working efficiently. The good news is that it’s super easy to clean a microwave filter—no tools required!

How to Keep Your Microwave Clean for Longer

Having a sparkling microwave can feel like a major accomplishment. Keep it cleaner for longer by doing the following:

Cover Your Food: Prevention is key. Before turning your microwave on, place a microwave-safe food cover or paper towel over any food that can splatter. Clean Spills Immediately: Fresh spills are way easier to clean up compared to baked-on messes. “If spills do occur, most can be removed with warm soap and water or with a cleaner formulated for microwave ovens,” says Peterson. Use Microwave-Safe Dishes: Always use microwave-safe dishes in your microwave. Some materials can melt or spark, leading to messes or fires. The dish should say “microwave-safe” on the bottom (or on the original packaging) and should not get too hot when used. Follow Cook Times: One of the most common causes of microwave messes is overcooking food. To prevent this from happening, always follow the recommended cooking times. Lowering the power setting can also prevent food from overheating.Clean Routinely: Again, aim for a once-monthly deep clean of your microwave to keep it sparkling!
