Microwaves rarely look dirty all at once. A splash of pasta sauce here, a little grease there, and before long, the inside is covered with dried-on food and lingering odors that become harder to remove each time you reheat a meal.
Fortunately, how to clean a microwave doesn’t have to involve harsh chemicals or hours of scrubbing. A few everyday household ingredients can loosen stubborn messes, freshen the interior, and leave your microwave looking almost new again.
1. How to Clean a Microwave: Quick Answer
If you’re short on time, these methods can handle almost every type of microwave mess:
- Vinegar and steam: Best for loosening dried-on food and everyday grease.
- Lemon and water: Great for removing light stains while freshening odors.
- Dish soap: Works well on fresh splatters and greasy surfaces.
- Baking soda paste: Ideal for stubborn stains that won’t wipe away easily.
- Wash the turntable separately: Clean it with warm, soapy water just like any other glass dish.
- Wipe the door and exterior: Don’t forget the handle, buttons, and vents where fingerprints and grease collect.
- Deodorize after cleaning: Leave the microwave smelling fresh by removing lingering odors before using it again.
The best method depends on what you’re trying to remove. Light spills usually need only a quick wipe, while burnt-on food and lingering smells often respond better to steam and a little extra soaking time.
2. Before You Clean Your Microwave
Before learning how to clean a microwave, remove the glass turntable, rotating ring, and any other removable accessories so you can reach food splatters and grease underneath them.
Gather the supplies required for your chosen method, such as:
- White vinegar or fresh lemon
- Baking soda or dish soap
- Warm water
- A microwave-safe bowl
- A microfiber cloth or nonabrasive sponge
- Paper towels
For routine interior cleaning, you generally do not need to unplug the microwave. However, disconnect it before wiping near the control panel, vents, cord, or other electrical areas.
Never spray cleaner directly onto the appliance. Apply it to the cloth first to prevent liquid from entering electrical components.
3. 7 Easy Ways to Clean a Microwave
The right method depends on the mess. Fresh splatters may only need dish soap, while dried food, grease, and odors are easier to remove with steam or baking soda.
Before using any method, check your microwave’s owner’s manual for model-specific cleaning instructions. Use microwave-safe containers, avoid abrasive cleaners, and handle heated bowls carefully.
Steam With Vinegar (Best All-Around Method)
Learning how to clean a microwave with vinegar is useful for loosening dried food and greasy residue.
- Add 1 cup of water and 1 tablespoon of white vinegar to a microwave-safe bowl.
- Heat it for two to five minutes until steam fills the microwave.
- Leave the door closed for a few more minutes, carefully remove the hot bowl, and wipe the walls, ceiling, floor, and door with a damp cloth.
Clean With Lemon (Best for Freshening Odors)
Lemon steam helps soften light grease while reducing everyday food odors.
- Squeeze half a lemon into a microwave-safe bowl containing about 1 cup of water, then place the lemon half in the bowl.
- Heat the mixture for two to five minutes until steam forms.
- Let it sit with the door closed briefly, remove the bowl carefully, and wipe the interior with a microfiber cloth or nonabrasive sponge.
Use Dish Soap for Light Grease
Dish soap is often enough for recent spills, fingerprints, and a thin layer of grease.
- Add a few drops of mild dish soap to warm water, then dip a soft cloth or nonabrasive sponge into the solution.
- Wring out excess water before wiping the interior.
- Go over each surface again with a clean, damp cloth to remove soap residue, then dry the microwave before replacing the turntable.
Remove Stubborn Stains With Baking Soda
For anyone wondering how to clean a microwave with baking soda, a paste can help loosen stains that remain after steaming.
- Mix baking soda with a small amount of water until it forms a spreadable paste.
- Spread the paste over burnt-on food or stubborn stains and leave it in place for five to ten minutes.
- Wipe it away gently with a damp cloth.
- Repeat the treatment if needed rather than using steel wool or harsh scrubbers that could scratch the microwave’s interior.
Wash the Turntable Separately
The glass turntable and rotating ring often collect spills that are easy to miss during routine wiping.
- Remove both parts once they have completely cooled.
- Wash them in warm, soapy water using a soft sponge, or place them in the dishwasher if the manufacturer allows it.
- Avoid moving a hot glass tray directly into cold water because sudden temperature changes may crack it.
- Dry each part before reinstalling it.
Clean the Microwave Door and Exterior
Grease, fingerprints, and food residue can build up around the microwave door, handle, and control panel.
- Apply mild dish soap and water to a microfiber cloth rather than spraying cleaner directly onto the appliance.
- Wipe the exterior carefully, especially around vents and electronic controls.
- Follow with a clean, damp cloth to remove residue, then dry the surface.
Note: Check the owner’s manual before using vinegar on specialty finishes.
Deodorize the Microwave After Cleaning
Knowing how to clean the inside of a microwave also involves removing the food residue that causes unpleasant smells.
- After wiping the interior, heat a microwave-safe bowl containing 1 cup of water and a small amount of baking soda for two to three minutes.
- Leave the door closed briefly so the steam can circulate, then wipe away the condensation.
- Keep the door open afterward to help the microwave air out completely.

4. How to Remove Burnt Food and Stubborn Stains
When learning how to clean a microwave, start by softening burnt-on food instead of scrubbing it immediately.
Heat a microwave-safe bowl of water with a little vinegar or lemon juice for 3 to 5 minutes, then leave the door closed briefly so the steam can loosen the stain.
Wipe the area with a microfiber cloth or nonabrasive sponge. If marks remain, apply a baking soda paste, let it sit for 5 to 10 minutes, and wipe again. Repeat as needed rather than scraping the surface.
Avoid steel wool, abrasive powders, and harsh scouring pads, which may damage the interior coating.
Finish by gently cleaning around the door edges and seals so food buildup does not interfere with the door closing properly.
5. How to Keep Your Microwave Clean Longer
Once you know how to clean a microwave, a few simple habits can help prevent grease, stains, and odors from building up again. Regular wiping and covering food while heating can reduce the need for deep cleaning.
- Cover food with a microwave-safe lid or paper towel before heating to reduce splatters.
- Wipe up spills as soon as the microwave has cooled. Fresh messes come off much more easily than dried-on stains.
- Leave the door open for a minute after cooking strong-smelling foods to help moisture and odors escape.
- Clean the turntable every week, especially if you use the microwave daily.
- Wipe the interior with a damp cloth every few days to prevent grease from accumulating.
- Deep clean the microwave every few weeks, or more often if it’s used frequently.
6. FAQs
What is the best way to clean the inside of a microwave?
For most situations, steaming a bowl of equal parts vinegar and water is the most effective method. The steam softens grease and dried food, making it easy to wipe the interior clean without heavy scrubbing.
Is it better to clean the microwave with lemon or vinegar?
Both work well, but they serve slightly different purposes. Vinegar is more effective at cutting through grease and loosening stubborn residue, while lemon is better for freshening odors and removing light stains. Choose the one that best matches your cleaning needs.
What not to clean a microwave with?
Avoid steel wool, abrasive scouring pads, bleach, and harsh chemical cleaners that can damage the microwave’s interior or leave behind harmful residue. Never spray cleaning products directly into vents or electrical components.
How do you clean a smelly microwave?
Steam the inside with lemon or vinegar, then wipe every surface thoroughly. If odors remain, leave a bowl of baking soda, activated charcoal, or dry coffee grounds inside the microwave overnight to absorb lingering smells naturally.
7. Conclusion
Grease, food splatters, and unpleasant odors don’t have to become permanent kitchen problems. With the right cleaning method and a few everyday ingredients, you can keep your appliance looking and smelling fresh with minimal effort.
Once you know how to clean a microwave, regular maintenance only takes a few minutes and helps prevent stubborn buildup before it starts.
