Microwaves are one of the most convenient kitchen appliances—but they can also become one of the messiest. A quick reheat of soup, pasta, or leftovers can lead to splatters, spills, and greasy buildup that, if not addressed quickly, harden into stubborn grime. Over time, these stuck-on food particles and lingering smells make your microwave not only unsightly but also unhygienic.
Fortunately, you don’t need harsh chemicals or expensive cleaning products to restore your microwave’s sparkle. With just a lemon, water, and a microwave-safe bowl, you can lift grime, eliminate odors, and make your microwave look and smell fresh in just minutes. This method is safe, natural, effective—and it leaves behind a refreshing citrus scent.
Let’s walk through the simple but powerful process of deep-cleaning your microwave using this all-natural solution.
Why Use Lemon to Clean a Microwave?
Natural Degreasing Power
Lemon contains natural acids that break down grease and food particles, making them easier to wipe away. The citric acid in lemon works like a natural disinfectant and degreaser—without leaving behind harsh chemical residue.
Steam Loosens Grime
When heated, the water and lemon mixture creates steam that softens hardened food splatters stuck to the walls and ceiling of your microwave. This makes them easy to wipe off without scrubbing.
Leaves a Fresh Smell
No artificial fragrance needed. Lemon leaves behind a light, clean citrus scent that naturally freshens the inside of your microwave.
Safe and Non-Toxic
This method is food-safe and eco-friendly. No chemical fumes, synthetic cleaners, or complicated steps—just two ingredients you already have in your kitchen.
What You’ll Need
Supplies:
- 1 microwave-safe, heatproof bowl (ceramic or glass is ideal)
- 1 fresh lemon
- 1 cup of water
- A clean microfiber cloth or sponge
- Dish soap (optional for extra cleaning power)
- Access to warm, soapy water or a dishwasher (for the turntable)
Step-by-Step Guide to Deep Clean a Microwave
Slice and Prep
Cut one lemon into several wedges or thick slices. Place the lemon pieces into the heatproof bowl and add one cup of water. Make sure the bowl is only about half full to prevent boiling over.
Steam It Up
Place the bowl inside your microwave. Set the microwave to run on high for 5 minutes. The water should come to a full boil, releasing lemon-infused steam that coats the interior surfaces.
Let It Sit
Once the microwave turns off, don’t open the door immediately. Leave the hot lemon-water bowl inside for 15 additional minutes. This allows the steam to continue loosening grime and gives the lemon more time to deodorize.
Keep the microwave closed during this time to trap all that beneficial steam inside.
Wipe It Down
Carefully open the microwave door. Use oven mitts or a thick cloth to safely remove the hot bowl. Be cautious—both the bowl and water will be very hot.
Unplug the microwave or switch it off at the power point before cleaning. Use a clean microfiber cloth to wipe down all the interior surfaces, including:
- The ceiling
- Walls
- Door (inside and around the seal)
- Floor of the microwave
If you need more cleaning power, dip your cloth into the warm lemon water in the bowl and continue wiping.
Clean the Turntable
Remove the microwave’s glass turntable and wash it by hand with warm, soapy water. If it’s extra greasy or has baked-on residue, let it soak for 10–15 minutes before scrubbing.
Alternatively, place it in the dishwasher if it’s labeled as dishwasher-safe.
Dry the turntable thoroughly and return it to the microwave once you’ve cleaned everything else.
Tips for Best Results
- Use fresh lemon: Bottled lemon juice lacks the same fragrance and effectiveness as a real lemon.
- Don’t skip the steam time: Leaving the microwave closed after heating helps the steam work its magic.
- Use a microfiber cloth: These are more effective than paper towels and don’t leave behind lint.
- For tough spots: Apply a paste made from baking soda and a few drops of water, let it sit for a few minutes, then scrub gently with a soft sponge.
- Regular maintenance: Use this steam-clean method once a week or after any big spill to keep your microwave in top shape.
- Avoid metal bowls: Only use ceramic or glass bowls that are microwave-safe to prevent sparks or damage.
Optional Variations for Added Cleaning Power
- Add vinegar: If your microwave is extra greasy, add a tablespoon of white vinegar to the lemon-water mix before microwaving.
- Add essential oils: For added fragrance, a drop or two of lemon or tea tree essential oil can complement the lemon and boost antimicrobial effects.
- Double the lemons: If your microwave is particularly smelly or dirty, use two lemons instead of one.
FAQs
Can I use bottled lemon juice instead of fresh lemon?
You can, but fresh lemons are more effective. The natural oils in the lemon peel add extra cleaning power and fragrance that bottled juice doesn’t offer.
How often should I clean my microwave this way?
For best results, aim to do a steam clean once a week, or more often if you use your microwave daily or experience frequent spills.
Is this method safe for all microwave types?
Yes. As long as you use a microwave-safe bowl and avoid overfilling it, this method is safe for all standard home microwaves. Always monitor while it runs and avoid leaving the microwave unattended.
What if the stains don’t come off?
If some grime remains after wiping, repeat the steam process or follow up with a baking soda paste. For extra-tough stains, let the baking soda sit for 5–10 minutes before scrubbing.
Can I clean the outside of the microwave the same way?
Use a damp cloth dipped in the lemon water to wipe the exterior. Avoid getting water into the vents. For buttons or touch screens, use a soft dry cloth or a slightly damp microfiber cloth.
Will this method remove burnt food smells?
Yes, especially if the smell is recent. The lemon helps neutralize bad odors. For persistent smells, repeat the cleaning process or add a few drops of vanilla extract to the lemon water.
