Why do I need to clean my over-the-range microwave?

It may seem like just one more thing you have to do in a never-ending list of household chores, but regularly cleaning your microwave is very important for:

• Preventing food spills and splatters that can harbor bacteria and mold, which pose health risks
• Odor control, since residue from food can lead to unpleasant smells, which can transfer to other dishes
• Increasing the lifespan of your microwave                                                                             
• Staying safe, since food particles can catch fire if they overheat
• Maintaining aesthetics so that it’s more inviting to use

What you’ll need to clean your microwave

• Dish soap
• White vinegar
• Water
• Baking soda 
• A soft sponge or microfiber cloth
• Microwave-safe bowl
• A toothbrush or small brush for corners
• Lemon (optional for deodorizing)
• Paper towels

NOTE: Natural or mild cleaning methods are the safest for the inside of a microwave. You should always avoid using bleach, abrasive cleaners and scouring pads, since these can damage the interior and exterior finishes of your microwave. 

General microwave cleaning steps

1. Remove the microwave turntable and roller ring (if present). Wash them in the sink using warm water and dish soap. Let them dry completely before placing them back in.
2. Fill a microwave-safe bowl with water and 2 tablespoons of white vinegar (or a few lemon slices for a fresh scent). Place the bowl inside the microwave and heat on high for 3–5 minutes so the steam can loosen any stuck-on food or grease.
3. Unplug your microwave from the power outlet once you’ve completed the previous steps.
4. Use a soft sponge or microfiber cloth to wipe the inside of the microwave. For stubborn stains and stuck food, dip the sponge in the vinegar solution or make a paste with baking soda and water, then scrub gently.
5. Clean the outside of the door with a glass cleaner.
6. Check underneath your microwave for any vent filters. If these are metal mesh, you can remove them and soak them in warm soapy water for about 15 minutes, then scrub them clean with a brush. Let the filters air-dry completely before re-installing them. If your microwave has charcoal filters, you’ll need to replace them since they can’t be cleaned.
7. Wipe down the interior and outside of the microwave with a damp (NOT soaking wet)  cloth or sponge and mild dish soap. Pay special attention to the control panel and handles, where fingerprints and smudges accumulate. For stainless steel-finished microwaves, use a stainless steel cleaner or a solution of water and white vinegar to wipe in the direction of the grain for a streak-free finish.
8. Check the underside of your over-the-range microwave, where the vent and light are located. This area can collect grease and dust. Use a degreasing cleaner or a mixture of dish soap and water to clean this spot.
9. Once everything is clean and dry, replace the turntable and filters and plug the microwave back in.

How to remove stains from an over-the-range microwave

There are several ways to get discoloration out of your unit. Try one of these methods today!

Steam cleaning method

Ingredients:

• Water
• Lemon juice or vinegar

Steps:

1. Fill a microwave-safe bowl with 1 cup of water.
2. Add a few tablespoons of lemon juice or vinegar to the water (both act as natural cleaners).
3. Microwave the bowl on high for 3-5 minutes. The steam will loosen tough food stains and grease.
4. Let the bowl stand for 1-2 minutes, then carefully remove the bowl (it may be hot).
5. Wipe down the interior with a soft, damp cloth or sponge to remove the loosened stains.

Baking soda paste method

Ingredients:

• Baking soda
• Water

Steps:

1. Mix baking soda with a small amount of water to form a thick paste.
2. Apply the paste to the stained areas in the microwave.
3. Let the paste sit on the stains for 5-10 minutes to break them down.
4. Use a soft, non-abrasive sponge to gently scrub the stains.
5. Wipe away the paste with a damp cloth.
6. Dry the microwave with a clean towel.

Vinegar and baking soda solution

Ingredients: 

• Vinegar
• Baking soda
• Water

Steps:

1. Sprinkle baking soda on the stained area.
2. Spray or gently pour vinegar over the baking soda. It will start to fizz, which helps lift the stain.
3. Let the mixture sit for 5 minutes.
4. Scrub the stains with a soft sponge.
5. Wipe the area with a damp cloth to remove any residue, then dry with a towel.

How to remove odors from your over-the-range microwave

Baking soda method

Baking soda naturally absorbs odors, which can help your microwave smell fresh again.

1. Place an open box of baking soda or a small bowl of baking soda inside the microwave.
2. Let the box sit for a few hours or overnight.
3. Remove the baking soda and wipe down the microwave.
4. Leave the microwave door open for several hours or overnight to let it air out.

Activated charcoal method

1. Place a few pieces of activated charcoal or an open container of activated charcoal inside the microwave.
2. Leave it for 24 hours to absorb strong odors.
3. Remove the charcoal and wipe the microwave clean.
4. Leave the microwave door open for several hours or overnight to let it air out.

Over-the-range microwave maintenance tips

If you want to keep your microwave running as long as possible, follow these simple tips.

• Wipe down the inside of the microwave after every use to remove spills and splatters. If food particles are left for too long, they can harden and become difficult to remove.
• Avoid using bleach or abrasive cleaners on your microwave as they can damage the surface.
• Remove the grease filter every 1–3 months (depending on frequency of use and/or manufacturer guidelines) and wash it in warm soapy water. Some filters can be washed in the dishwasher, but check your model before washing it this way. Allow the filter to dry completely before putting it back. If the filter is too clogged or damaged, replace it with a new one.
• Replace the charcoal filter every 6–12 months, or according to the manufacturer’s instructions. 
• Always close the microwave door gently. Repeatedly slamming the door can cause wear and tear on the latch and hinges, which might eventually cause the microwave to stop working correctly.
• To prevent moisture buildup in and around the microwave, leave the microwave door open for a few minutes after cooking to let steam escape. This helps prevent mold and mildew from forming inside.
• Always use microwave-safe dishes and containers. Products that aren’t labeled as microwave-safe may cause damage to the interior or pose a fire hazard.
