You do not need expensive products or complicated techniques to achieve a spotless microwave. Keep reading to learn simple, effective methods for tackling everyday messes, tough stains, and unwanted odors.
Quick Answer: How to Clean a Microwave?
The quickest way to clean a microwave is with a steam-cleaning method using water and either vinegar or lemon.
Fill a microwave-safe bowl with one cup of water and add two tablespoons of white vinegar or the juice and sliced halves of one lemon.
Microwave on high for three to five minutes until steam forms, then keep the door closed for two to three minutes.
The trapped steam loosens dried food residue, grease, and light stains. Wipe the interior clean with a microfiber cloth or sponge. No scrubbing needed for routine messes
Deep Microwave Cleaning for Tough Messes
When routine wiping is not enough, a deep clean helps remove stubborn grease, dried food residue, and lingering odors. The process takes about 15–20 minutes and leaves your microwave looking and smelling fresh.
- Remove the turntable and roller ring: Take out both removable parts and set them aside for washing. Allow them to cool completely before placing them in water to prevent cracking.
- Steam the interior: Fill a microwave-safe bowl with1 cup of water and 2 tablespoons of white vinegar. Microwave on high for 4–5 minutes, then let it sit for 2 minutes before opening the door.
- Wipe the interior: Use a microfiber cloth or soft sponge to wipe the ceiling, walls, and floor of the microwave. Work from top to bottom so debris falls downward and is removed during the final wipe.
- Address stubborn stains: Apply a paste made from baking soda and water to any remaining stains. Let it sit for 3–5 minutes, then wipe the area clean with a damp cloth.
- Wash removable parts: Clean the turntable and roller ring in warm, soapy water. If the owner’s manual confirms they are dishwasher-safe, place them in the dishwasher. Dry thoroughly before reinstalling.
- Clean the door and exterior: Wipe the door glass, handle, and exterior surfaces. For the control panel, apply cleaner to the cloth rather than spraying directly onto the buttons.
- Leave the door open briefly: Allow the microwave to air out for 5–10 minutes after cleaning to help moisture evaporate and reduce lingering odors.
How to Clean a Microwave: Best Homemade Methods
Natural cleaning solutions can remove grease, loosen food residue, and eliminate odors without relying on harsh chemicals.

How to Remove Stubborn Microwave Stains?
Even with regular cleaning, microwaves can develop burnt residue, stubborn stains, grease buildup, and lingering odors.
1. Removing Burnt Food Residue
Burnt food residue can become difficult to remove if it remains inside the microwave for too long. Start by steam-cleaning the interior with a bowl of water and vinegar or lemon to soften the buildup.
After the residue loosens, gently wipe the area with a soft sponge or microfiber cloth.
For stubborn spots, apply a baking soda paste and let it sit for a few minutes before wiping clean. If the residue is heavily carbonized, a second round of steaming before applying the paste improves results.
Avoid using abrasive scrubbers, which can scratch and permanently damage the interior coating
2. Getting Rid of Burnt Smells
Burnt odors can linger in a microwave even after visible residue has been removed. To eliminate unpleasant smells, steam-clean the appliance with water and lemon or vinegar, then wipe all interior surfaces thoroughly.
If the odor persists, place an open container of baking soda in the microwave for several hours or overnight to absorb lingering odors.
You can also leave a bowl of coffee grounds inside the appliance for additional odor absorption. Regular cleaning helps prevent burnt smells from becoming trapped in the interior.
3. Cleaning Heavy Grease Buildup
Heavy grease buildup is common in microwaves used frequently for reheating oily foods. Begin by steam-cleaning the interior to loosen greasy residue.
Next, wipe the surfaces with a cloth dampened in warm water and a small amount of dish soap.
Pay close attention to the ceiling, walls, and door where grease often accumulates. For stubborn areas, allow the soapy solution to sit briefly before wiping again.
Consistent cleaning prevents grease from hardening and becoming more difficult to remove over time.
4. Removing Stubborn Stains and Discoloration
Some microwave stains can remain visible even after routine cleaning, especially if food splattering has been repeatedly heated.
A baking soda paste can help lift stubborn marks without damaging the interior surface.
Apply the paste to stained areas and allow it to sit for several minutes before gently wiping it away with a damp cloth.
For light discoloration, steam cleaning may also help loosen residue contributing to the problem. Addressing stains early often prevents them from becoming permanent and harder to treat later.
5. If Odors Keep Coming Back
If unpleasant odors continue returning after cleaning, hidden food particles or grease buildup may still be present inside the microwave.
Inspect areas around the turntable, roller ring, door seals, and vents where residue can accumulate unnoticed. Perform a thorough steam cleaning and wipe every surface carefully.
Leaving an open container of baking soda inside overnight may help absorb persistent smells.
If odors persist despite repeated cleaning, check the appliance for burnt residue in hard-to-reach areas, which may require deeper maintenance.
What Do Reddit People Say About How to Clean a Microwave?
