how to clean inside of microwave oven
The most effective method for a deep clean uses steam to loosen dried-on food. This approach minimizes scrubbing and uses common household items. It’s safe for all microwave interiors and very effective.
What You Will Need
Gather these simple supplies before you start. You likely have most of them already.
- A microwave-safe bowl or large cup
- Water
- White vinegar or lemon juice (for cutting grease and odors)
- A clean cloth or sponge (non-abrasive)
- A mild dish soap
- A plastic spatula or old credit card (for stubborn spots)
Step-by-Step Deep Cleaning Process
Follow these steps in order for the best results. The steam does most of the hard work for you.
Step 1: Create the Cleaning Solution
Fill your microwave-safe bowl with 1 to 2 cups of water. Then, add one of the following to boost cleaning power:
- Option A: 1/2 cup of white vinegar.
- Option B: The juice of one lemon (or 2-3 tablespoons of bottled lemon juice).
The acid in the vinegar or lemon helps break down grease and neutralizes lingering odors. Both are natural and food-safe.
Step 2: Generate Steam
Place the bowl in the center of the microwave. Heat it on high power for 3-5 minutes, or until the solution is boiling and the window is very steamy. The goal is to fill the interior with hot, moist steam. This steam will soften all the dried food splatters.
Step 3: Let the Steam Work
This is a crucial patience step. Do not open the microwave door immediately. Let the bowl sit inside the closed microwave for another 5-10 minutes after heating. This allows the steam to condense on the walls and ceiling, further loosening the grime. The longer it sits, the easier the wipe-down will be.
Step 4: Wipe Down the Interior
Carefully remove the hot bowl—use oven mitts. Dip your cloth or sponge in the warm (now slightly cooled) vinegar or lemon water. Wring it out so it’s damp, not dripping. Wipe down all interior surfaces: the ceiling, walls, door, and the turntable. The grime should come off with minimal effort. For the turntable, you can usually remove it and wash it separately in the sink with warm soapy water.
Step 5: Address Stubborn Spots
For any remaining spots, apply a small drop of dish soap directly to your cloth and gently scrub the area. For crusty, baked-on splatters, a plastic spatula can be used very gently to lift the edge. Do not use metal scrapers or abrasive pads, as they can scratch the interior surface, which can lead to rust and makes future cleaning harder.
Step 6: Final Rinse and Dry
Rinse your cloth with clean water and wipe over all surfaces to remove any soap or vinegar residue. Use a dry towel to thoroughly dry the interior, including the door seal. This prevents water spots and ensures no moisture is trapped. Finally, replace the clean, dry turntable.
Alternative Natural Cleaning Methods
If you don’t have vinegar or lemons, other kitchen staples work well too.
Baking Soda Paste
For tough, sticky stains, make a paste with baking soda and water. Apply it directly to the stain and let it sit for 5 minutes. The baking soda acts as a gentle abrasive. Wipe it away with a damp cloth. This is excellent for caramelized sugar or sauce stains.
Steam with Water Only
For light cleaning or odor removal, simply heating a bowl of plain water works. Follow the same steam process. The moisture alone will loosen light splatters and refresh the microwave’s interior.
What to Avoid When Cleaning
Using the wrong products can damage your microwave. Steer clear of these.
- Harsh Chemicals: Avoid oven cleaners, bleach, or other strong corrosive chemicals. Their fumes can linger and be hazardous, and they may damage the interior finish.
- Abrasive Tools: Never use steel wool, metal scouring pads, or harsh scrub brushes. They create microscopic scratches.
- Commercial Degreasers: While powerful, they are often unnecessary and can leave a strong chemical smell. Stick to mild dish soap for grease.
Maintaining a Clean Microwave
Prevention is easier than deep cleaning. These habits will keep your microwave looking fresh between major cleans.
Use a Microwave Cover
This is the single best tip. A microwave-safe plate cover, splatter lid, or even a paper towel placed over food will catch most pops and splatters. It’s much easier to wash a cover than to clean the entire cavity.
Wipe Spills Immediately
If something does spill or bubble over, wipe it up right away with a damp cloth while the interior is still warm and the spill is soft. A quick 10-second wipe now saves a 10-minute scrub later.
Regular Quick Wipes
Once a week, give the interior a quick wipe with a damp cloth or a disinfectant wipe designed for appliances. This prevents buildup from ever getting out of control.
Address Odors Promptly
For odors, heat a bowl of water with a few lemon slices or a tablespoon of baking soda for 2-3 minutes. Let it sit, then wipe. This neutralizes smells before they set in.
Cleaning Specific Microwave Parts
Don’t forget these key components that often get overlooked during cleaning.
The Turntable and Ring
Remove the glass turntable and the supporting ring underneath. Wash them in warm, soapy water in the sink or place them in the dishwasher if they are dishwasher-safe (check your manual). Dry completely before reassembling to prevent mold or mildew on the roller wheels.
The Door and Seal
Wipe the inside of the glass door and the plastic or rubber door seal (gasket) that runs around the edge. Food and grease can accumulate here, preventing the door from sealing properly, which is a safety issue. Use a cotton swab to get into the crevices of the seal.
The Control Panel and Exterior
With the microwave unplugged or turned off at the circuit, wipe the control panel and exterior with a damp cloth. For stainless steel, use a cleaner appropriate for the finish to avoid streaks. Avoid spraying liquid directly onto the controls; spray it on the cloth instead.
Troubleshooting Common Problems
Sometimes, you encounter specific challenges. Here’s how to handle them.
Removing Burned-On Food
For a severe, burned-on mess, you may need to repeat the steam process twice. Let the steam sit for a full 15 minutes. Use the baking soda paste method on the worst areas, letting the paste sit for 20-30 minutes before gently scrubbing.
Persistent Grease Film
A thin, greasy film can remain after wiping. Add a drop of dish soap to your final rinse water. The soap will cut through taht residual grease without leaving a strong scent like vinegar might.
Stubborn Odors
If odors persist after cleaning, place an open box of baking soda inside the microwave when it’s not in use, just like you would in a refrigerator. Replace it every 1-2 months. This will continously absorb odors.
Safety Precautions
Always prioritize safety when cleaning any appliance.
- Unplug the microwave or turn off the power at the breaker before cleaning the exterior, especially around the control panel, to avoid any risk of shock.
- Always allow the microwave and the cleaning bowl to cool sufficiently before handling them to prevent burns from steam or hot surfaces.
- Ensure the interior is completely dry before plugging the appliance back in and using it. Moisture and electricity do not mix.
- Never turn on the microwave when it is empty, as this can damage the magnetron, its key component.
FAQ Section
How often should I clean my microwave?
For light maintenance, a quick wipe-down once a week is ideal. A full deep clean using the steam method should be done at least once a month, or more often if you use your microwave frequently for messy foods.
Can I use bleach to clean my microwave?
No, it is not recommended. Bleach is a corrosive chemical that can damage the interior surfaces of your microwave. Its fumes are also hazardous and can linger, potentially contaminating your food. Stick to vinegar, lemon, baking soda, or mild soap.
What is the fastest way to clean a microwave?
The steam method described above is the fastest effective method. The entire process, from heating to drying, takes about 15 minutes of mostly hands-off time. It’s much quicker and safer than aggressive scrubbing on dry stains.
Why does my microwave smell after cleaning?
If a smell remains, it could be in the door seal or ventilation filters (if your model has them). Clean the seal thoroughly with a vinegar solution. Also, ensure you rinsed away all cleaning solution residue, as vinegar or soap left behind can create a smell when heated.
Is it safe to use commercial all-purpose sprays?
It’s best to avoid them. Many contain chemicals or fragrances not intended for food appliance surfaces. If you do use one, ensure it’s labeled as kitchen-safe and always rinse the interior thoroughly with a water-dampened cloth afterwards to remove any chemical residue.
A clean microwave is more pleasant to use, more efficient, and safer. By incorporating the simple steam method and regular maintenance habits, you can keep your appliance in excellent condition for years to come. The process is straightforward and requires minimal effort when done consistently.
