How to Clean Your Microwave and Make It Last
8 expert tips to help extend the life of your over-the-range appliance
Over-the-range microwaves are built into the cabinetry and bolted to a wall, so replacing one that conks out is no simple chore.
To avoid replacing yours more than about once every 10 years—which is how long most manufacturers tell us they should last—you’ll want to take care of it.
Your microwave may not get as grimy as your oven, but even so, one of the best ways to keep it humming along is to keep it clean. That means wiping down the interior when someone heats up a bowl of pasta without covering it, and regularly cleaning the grease filters that catch the cooking fumes from the rangetop below, especially if you often fry food.
The over-the-range models in our microwave ratings range from under $200 to $2,000. Getting one repaired can cost at least a few hundred dollars. If you’re unsure of whether it’s worth investing in repairs to your broken over-the-range microwave, we’ve done the calculations for you.
But if your over-the-range microwave is working and you want to keep it that way, here are some simple things you can do on a daily or weekly basis to make your microwave last. (Word to the wise: Most of these tips work for countertop models too.)
1. Be quick with the cleanup. Sponge up spills as soon as they occur. Bits of food left behind can absorb some of the microwave’s energy when you turn it on again, creating a hot spot that can damage the interior. Take special care not to scratch the protective mesh inside the door if it’s exposed, because it prevents microwaves from escaping and zapping you.
To remove cooking stains, wipe the walls and bottom of the oven with a hot, damp cloth. Wash removable parts, such as the turntable, in hot water and dishwashing liquid.
To mask odors, place a bowl of water containing ¼ cup of lemon juice in the oven and run it on high for 1 minute. Remove the bowl and wipe the oven cavity, using the condensation that will have formed to clean it. Wipe stains using plain water. Repeat if necessary. Scrape off stubborn stains with a plastic credit card.
