How to Keep Your Westinghouse Microwave Clean and Running Well

What Westinghouse Microwaves Are and How to Care for Them

Westinghouse microwaves are compact countertop models sold through major retailers and online. They heat food using microwave radiation and come in standard sizes—most are 0.7 to 1.1 cubic feet. Like any microwave, they need regular cleaning inside and out to prevent odor buildup, keep the interior window clear, and avoid splatters that harden and become difficult to remove.

The care routine is straightforward: wipe the exterior weekly, clean the interior after spills, and descale the vents monthly. Because Westinghouse models are mass-produced and sold without extensive documentation, you may not have the original manual. This guide covers the maintenance tasks that apply to nearly all Westinghouse microwaves, regardless of the specific model or year.

Key Takeaways

• Wipe the exterior with a damp cloth weekly to prevent dust and grease buildup on the control panel and door handle.
• Clean the interior immediately after spills by wiping with a damp microwave-safe cloth or paper towel—never use abrasive scrubbers that can damage the interior coating.
• Steam-clean the interior monthly by microwaving a bowl of water with lemon or vinegar for 3 to 5 minutes to loosen stuck-on food and reduce odors.
• Check the vent grilles on the top or sides monthly and wipe away dust with a soft brush or cloth to keep airflow clear.
• Never use metal utensils, foil, or harsh chemicals inside the microwave, as these damage the interior and create fire hazards.

Cleaning the Exterior and Control Panel

The outside of your Westinghouse microwave collects dust, fingerprints, and cooking grease. Wipe the exterior once a week with a soft, damp cloth—microfiber cloths work well. For the control panel, use the same damp cloth and wipe gently around the buttons and display. Avoid spraying liquid directly onto the panel; instead, dampen the cloth first and squeeze out excess water.

If the exterior has stubborn grease spots, add a drop of mild dish soap to the water. Wipe again with a cloth dampened in plain water to remove any soap residue. Dry the exterior with a clean, dry cloth to prevent water spots. Pay special attention to the door handle, which gets touched frequently and can harbor bacteria and grease.

Wiping Down the Interior After Spills

Food splatters inside the microwave during cooking. The sooner you clean them, the easier they come off. After the microwave cools slightly, open the door and wipe the interior walls, ceiling, and floor with a damp microwave-safe cloth or paper towel. Use gentle circular motions and avoid scrubbing hard, which can scratch the interior enamel coating.

For dried or stuck-on food, do not use steel wool, scouring pads, or abrasive cleaners. These damage the protective coating inside the microwave and can expose metal underneath, which creates rust and safety hazards. If food is very stuck, use the steam-cleaning method described below to soften it first, then wipe gently.

Steam-Cleaning to Loosen Food and Reduce Odors

Once a month, use steam to clean the interior and freshen the smell. Fill a microwave-safe bowl or mug with one cup of water and add the juice of half a lemon or two tablespoons of white vinegar. Place the bowl in the center of the microwave and run it on high for 3 to 5 minutes. The steam will condense on the walls and soften any stuck-on food.

When the time is up, carefully remove the hot bowl—use an oven mitt or kitchen towel. Let the microwave cool for a minute, then wipe the interior with a damp cloth. The steam loosens food, and the lemon or vinegar neutralizes odors. This method is safe, uses no harsh chemicals, and works on all Westinghouse models.

Checking and Cleaning the Vent Grilles

Westinghouse microwaves have vent grilles, usually on the top or sides, that allow heat and steam to escape. Dust and cooking particles accumulate in these grilles and block airflow, which makes the microwave work harder and can cause it to overheat. Check the grilles once a month and wipe them with a soft brush, old toothbrush, or dry cloth.

If dust is packed in tightly, use a vacuum with a brush attachment on low suction to gently pull debris out. Never poke into the grilles with sharp objects, as you may damage internal components. Keeping the vents clear ensures the microwave stays cool during use and prevents the motor from wearing out prematurely.

What Not to Use Inside Your Westinghouse Microwave

Certain materials and products damage the microwave or create safety hazards. Never use metal utensils, forks, or aluminum foil inside the microwave—metal reflects microwave radiation and can cause arcing (sparks). Do not use steel wool, scouring pads, or abrasive powders on the interior, as these scratch the enamel coating.

Avoid harsh chemicals like bleach, ammonia, or oven cleaner inside the microwave. These leave toxic residues that can transfer to food. Do not spray water or cleaning liquid directly onto the control panel or vents—liquid can seep into electrical components and cause malfunction. Stick to water, mild dish soap, lemon juice, and white vinegar, all of which are safe and effective.

Organizing What You Store Near Your Microwave

Keep the area around your Westinghouse microwave clear of clutter. Do not stack items on top of the microwave, as this blocks the vents and traps heat. Store microwave-safe containers, bowls, and covers in a nearby cabinet or drawer so they are within reach but not piled on the appliance itself.

If you keep paper towels, napkins, or plastic wrap near the microwave, store them in a drawer or on a shelf away from the heat vents. Paper products near active vents can dry out, become brittle, or catch fire if they touch hot surfaces. A clear, organized space around the microwave also makes it easier to wipe down the exterior and check the vents.

Frequently Asked Questions

Can I use vinegar and water to clean the inside of my Westinghouse microwave?

Yes. Mix equal parts white vinegar and water in a bowl, place it in the microwave, and run it on high for 3 to 5 minutes. The steam loosens food and the vinegar cuts grease and odors. Wipe the interior with a damp cloth afterward. This method is safe for all Westinghouse models.

What should I do if my microwave smells bad?

Odors usually come from old food residue or mold in the interior. Steam-clean with lemon water or vinegar once a month. Wipe spills immediately after they happen. If the smell persists, place an open box of baking soda inside the microwave overnight to absorb odors. Replace the baking soda every few weeks.

Is it safe to leave the microwave door open to air it out?

Yes, leaving the door open for a few minutes after use allows steam to escape and helps the interior dry. Do not leave it open for hours, as dust can settle inside. Close the door when you are done using the microwave to keep the interior clean.

How often should I deep-clean my Westinghouse microwave?

Wipe spills immediately, clean the exterior weekly, and steam-clean the interior once a month. If you use the microwave heavily or notice buildup, increase steam-cleaning to twice a month. This routine prevents odors, keeps the window clear, and extends the life of the appliance.

Can I use paper towels instead of cloth to clean the interior?

Yes, paper towels work well for wiping the interior after spills. They are disposable and convenient. For the exterior and control panel, a damp cloth is better because it reduces waste and gives you more control over moisture near the buttons and display.
