The Easiest Way to Clean a Microwave

How to clean a microwave is simpler than most people expect — and it takes less than 10 minutes. Here's the quickest way to do it:

That's it. No harsh chemicals. No scrubbing.

If you've ever opened a microwave and been hit with the smell of last week's reheated fish — or spotted a splatter of dried tomato sauce on the ceiling — you're not alone. Microwaves are one of the hardest-working appliances in the kitchen, and one of the most overlooked when it comes to cleaning.

The good news? Keeping yours fresh doesn't require anything fancy. A bowl of water, a lemon, and about 10 minutes is genuinely all you need.

Experts suggest cleaning your microwave at least once a week, or wiping up spills immediately when they happen. The longer food sits and hardens, the harder it is to remove.

Before we dive into the "how-to," let’s gather our tools. In our Los Angeles kitchens, we prefer natural, sustainable methods that don't involve harsh chemical fumes. Most of what you need is likely already in your pantry or sitting in a fruit bowl after a trip to the Hollywood Farmers Market.

To master how to clean a microwave, you will need:

We recommend avoiding abrasive materials like steel wool or "magic" melamine sponges. While they might seem helpful for tough stains, they can actually damage the protective coating on the interior walls of your microwave.

The steam method is the gold standard for microwave maintenance. Instead of scrubbing at hardened pasta sauce, we let the microwave do the work for us. By heating a liquid solution, we create a humid environment that rehydrates dried-on food, making it slide right off the walls.

When you start the process, pay special attention to the ceiling of the microwave. This is often the most neglected area, where splatters from soups and sauces accumulate and "bake" onto the surface every time you use the appliance.

Vinegar is a powerhouse in the kitchen. The acetic acid in white vinegar breaks down the molecular bonds of grease, making it the perfect choice for a deep clean.

If you aren't a fan of the smell of vinegar, seasonal citrus is your best friend. This method is popular in our Brentwood and Santa Monica communities where fresh lemons are a kitchen staple.

While the interior walls get the most attention, a truly clean microwave requires looking at the parts we often touch but rarely scrub.

Most glass turntables are dishwasher-safe, but you must be careful. Always let the turntable cool completely before washing it in the sink or dishwasher. If you put a hot glass tray into cool dishwater, the thermal shock could cause it to shatter. Wash it with warm, soapy water and a non-scratch sponge. Don't forget to wipe the roller ring (the little plastic wheels underneath) as food crumbs often get trapped there, causing a "crunching" sound when the tray rotates.

The handle and keypad are high-touch areas that can harbor bacteria. To clean the control panel without accidentally starting a 99-minute cook cycle, look for a "Control Lock" feature. Many modern microwaves allow you to lock the buttons for cleaning.

Wipe the exterior with a soft cloth dampened with water and a drop of dish soap. If you have a stainless steel model, always rub in the direction of the metal’s grain to prevent streaks. For a polished finish, you can use a specialized affresh® stainless steel cleaning spray or a simple glass cleaner on the exterior door.

If your microwave is mounted above your stove, it likely acts as a vent. These models have grease filters (usually metal mesh) on the bottom. Over time, these become clogged with aerosolized fat from your stovetop cooking.

The easiest way to clean a microwave is to prevent it from getting dirty in the first place. Here in Los Angeles, where we value efficiency and clean living, a few small habits can save you hours of scrubbing later.

Yes, in most cases, the glass tray is dishwasher-safe. However, you should always check your manufacturer's manual to be certain. The most critical safety tip is to ensure the tray has reached room temperature before it touches water. The roller ring and the plastic support should generally be hand-washed to prevent warping in the high heat of a dishwasher.

Burnt popcorn is the classic microwave tragedy. If the lemon steam method doesn't work, try baking soda. Mix 2 tablespoons of baking soda with 1 cup of water and steam it for 5 minutes. Afterward, place an open box of baking soda or a bowl of dry coffee grounds inside the microwave and leave the door closed overnight (with the power off). These materials are excellent at absorbing lingering carbon smells.

Absolutely. A mild dish soap is perfectly safe for the interior walls. However, the "steam first" method is still recommended because it prevents you from having to use too much soap. If you use an excessive amount of detergent inside, it can be difficult to rinse away completely, potentially leaving a soapy residue that could scent your food the next time you cook. Always follow a soap wipe with a rinse using a clean, damp cloth. Avoid using bleach or other harsh chemicals, as they can weaken the plastic components and leave behind toxic fumes.

At Edible L.A., we believe that a clean kitchen is the foundation of great seasonal cooking. Whether you're melting local butter for a summer corn dish or reheating a bowl of stew made with Glassell Park produce, a fresh microwave ensures your flavors remain pure.

By using natural ingredients like vinegar, lemon, and baking soda, you're not just maintaining an appliance; you're supporting a sustainable, toxin-free home environment. Regular maintenance—cleaning those grease filters monthly and giving the interior a weekly steam—will keep your microwave running efficiently for years to come.
