To deep clean a microwave, use a bowl of water and vinegar or lemon juice to steam off grime, then wipe down all surfaces with a non-abrasive cleaner. This method loosens stuck-on food and neutralizes odors without scrubbing for hours.
Deep cleaning your microwave involves steaming with a vinegar solution, removing the turntable for separate washing, and paying attention to the vent and door seals. Use a microfiber cloth and avoid abrasive pads that can scratch the interior.
- Steam power: Heating a bowl of water with vinegar or lemon for 3-5 minutes creates steam that loosens food residue.
- Turntable care: Remove the glass turntable and wash it in warm soapy water or in the dishwasher.
- Grease cutting: A paste of baking soda and water is effective for stubborn grease spots.
- Odor removal: Lemon juice or baking soda neutralizes odors; avoid bleach or ammonia.
1. Prepare a Steam Cleaning Solution
Fill a microwave-safe bowl with 1 cup of water and add either 2 tablespoons of white vinegar or the juice of one lemon. Vinegar cuts grease and deodorizes, while lemon leaves a fresh scent. Place the bowl in the center of the microwave.
For extra cleaning power, add a few drops of dish soap. Do not use any metal or foil in the microwave.
2. Steam the Interior
Microwave the bowl on high power for 3 to 5 minutes, until the mixture comes to a boil and the window steams up. Let it sit for 2 minutes after the microwave stops to allow the steam to penetrate the grime.
Be careful when removing the bowl—it will be hot. Use oven mitts. If the bowl is too hot to handle, leave it in place until it cools slightly.
3. Wipe Down All Surfaces
Remove the bowl and turntable. Dip a microfiber cloth or sponge in the warm vinegar water (or use a clean damp cloth) and wipe the interior ceiling, walls, and floor. The steam will have loosened most food splatters.
For stubborn spots, dip the cloth in a paste of baking soda and water (3 parts baking soda to 1 part water) and scrub gently. Avoid steel wool or abrasive scrubbers that can damage the enamel.
4. Clean the Turntable and Accessories
Wash the glass turntable and any roller rings in warm soapy water or place them in the dishwasher. Dry thoroughly before replacing. Wipe the turntable hub with a damp cloth.
If the turntable is stuck due to residue, soak it in warm soapy water for 10 minutes before scrubbing.
5. Deodorize and Polish
To remove lingering odors, place a bowl of water with a few lemon slices or 1 teaspoon of baking soda and microwave for 2 minutes. Wipe dry with a clean cloth.
For the exterior, use a spray of water and a drop of dish soap on a microfiber cloth. Avoid getting liquid into the vents. Polish with a dry cloth to remove streaks.
Pro Tips
- Clean the microwave door seal with a toothbrush dipped in vinegar to prevent mold buildup.
- Place a bowl of water with a wooden toothpick inside to prevent superheating when steaming.
- Use a silicone microwave cover when reheating food to reduce splatters and deep cleaning frequency.
- If your microwave has a charcoal filter, check and replace it every 6 months for odor control.
Common Mistakes to Avoid
- Using abrasive scouring pads or bleach-based cleaners that can scratch or damage the interior coating.
- Forgetting to unplug the microwave before cleaning the exterior vents or control panel.
- Spraying cleaner directly onto the control panel—liquid can seep inside and cause damage.
- Leaving the turntable in place during steaming, which can trap grime underneath.
FAQ

No, bleach can damage the interior and leave harmful fumes. Stick to vinegar, lemon, or baking soda.
How often should I deep clean my microwave?
Deep clean every 2-4 weeks if used daily, or immediately after a spill. Wipe down after each use for lighter maintenance.
My microwave still smells after cleaning. What should I do?
Place a bowl of water with 2 tablespoons of baking soda and microwave for 5 minutes, then leave the door open to air out. Also, check and clean the vent filter.
The Bottom Line
Regular deep cleaning keeps your microwave efficient and odor-free. By using this steam-and-wipe method, you can avoid harsh chemicals and extend the life of your appliance. For daily maintenance, simply wipe spills immediately and use a microwave cover.
