That microwave oven is a kitchen hero, but it can quickly become a splattered mess. Knowing how to clean a microwave oven properly is the key to keeping it fresh and efficient. A dirty microwave isn’t just an eyesore; old food splatters can affect how your food heats and even create lingering odors. This guide gives you the deep cleaning steps you need, using items you probably already have at home.
Let’s get started. First, you’ll want to gather your supplies. You won’t need any harsh chemicals. Most of this is about steam and elbow grease.
What You’ll Need for This Deep Clean
- A microwave-safe bowl or large cup
- Water
- White vinegar or lemon juice (your choice!)
- Dish soap
- Baking soda
- Clean microfiber cloths or sponges
- A soft-bristled brush (an old toothbrush works perfectly)
- A rubber spatula or plastic scraper (for stubborn bits)
How To Clean A Microwave Oven
This method uses steam to loosen all that baked-on grime. It makes the wiping part so much easier. Follow these steps in order for the best results.
Step 1: Prepare and Steam
First, take out any removable parts. This includes the glass turntable, the ring that it sits on, and any grill or tray. Set them aside for washing in the sink later.
Now, make your steam solution. Fill your microwave-safe bowl with 1-2 cups of water. Then add one of these:
- Option A: ½ cup of white vinegar.
- Option B: The juice of one lemon (you can toss the lemon halves in too for extra scent).
Both options work great. The acid helps cut through grease and leaves things smelling fresh.
Step 2: Run and Let Sit
Place the bowl in the center of your empty microwave. Run it on high power for 5-7 minutes, or until the window is very steamy and the liquid is boiling. Be careful when opening the door—a lot of hot steam will escape!
Here’s a pro tip: Do not wipe immediately. Just close the door again and let the microwave sit for another 5-10 minutes. This waiting time is crucial. The steam needs time to soften all the dried-on spills on the walls and ceiling.
Step 3: Wipe Down the Interior
After it has sat, carefully remove the hot bowl. Now, take your damp microfiber cloth and wipe down the entire inside. Start from the top (ceiling), then do the walls, and finish with the floor.
The grime should wipe away with minimal effort. For tougher spots, dip your cloth in the warm vinegar-water from the bowl for extra cleaning power. Use your soft-bristled brush for corners and around the door seal.
Dealing With Stubborn, Stuck-On Spills
If a spot is still resisting, make a simple paste. Mix a tablespoon of baking soda with a little water until it forms a spreadable paste. Apply it directly to the tough spot and let it sit for a minute. Then, gently scrub with your brush or cloth. The baking soda acts as a mild abrasive.
For really hard, carbonized spots, a plastic scraper can gently lift the edge. Be very gentle to avoid scratching the interior surface.
Step 4: Clean the Removable Parts
While the microwave is steaming, wash the turntable and ring. Use warm, soapy water in the sink. For any stains or grease on the glass tray, sprinkle it with baking soda and add a drop of dish soap. Scrub with a non-abrasive sponge, and it will come clean.
Rinse everything thoroughly and dry it completly before putting it back. A wet turntable can cause puddles.
Step 5: Don’t Forget the Exterior and Door
A full deep clean includes the outside. Wipe down the control panel, handle, and door with a cloth dampened with just water or a mild all-purpose cleaner. Always spray your cleaner onto the cloth, not directly onto the microwave, to avoid liquid getting into the electronics.
Pay special attention to the door seal (the gasket around the inside of the door). Wipe it thoroughly to remove any grease or crumbs that could prevent the door from sealing properly.
Step 6: Final Touch for Freshness
To eliminate any last odors, place a small bowl of baking soda inside the microwave and leave it overnight with the door closed. Just remember to take it out before you use it next! You can also wipe the interior one last time with a cloth rinsed in clean water.
How to Maintain a Clean Microwave
Deep cleaning is easier if you don’t let messes build up. Here are simple habits to adopt:
- Cover your food. Use a microwave-safe lid, plate, or even a paper towel to prevent major splatters.
- Wipe up small spills immediately after they happen, when they are still warm and soft.
- Give the interior a quick wipe with a damp cloth once a week during your regular kitchen cleaning.
These small steps mean you’ll rarely need a heavy deep clean.
Common Microwave Cleaning Mistakes to Avoid
Even with good intentions, some methods can cause damage. Here’s what to skip:
- Using harsh abrasives: Steel wool or rough scrub pads will scratch the interior finish, making it harder to clean next time and potentially damaging it.
- Spraying cleaner directly inside: This can damage the electrical components and the coating inside the microwave.
- Ignoring the steam step: Trying to scrub dried-on food without steaming first is a recipe for frustration and a sore arm.
- Putting the turntable back wet: This can lead to water spots and mineral deposits on the glass.
FAQ: Your Microwave Cleaning Questions Answered
Can I use bleach to clean my microwave?
No, you should not use bleach. It is too harsh and the fumes can be dangerous when trapped inside the appliance. The steam method with vinegar or lemon is safer and just as effective for disinfecting.
What if my microwave still smells bad after cleaning?
The baking soda trick overnight usually works. If odors persist, try steaming with a bowl of water mixed with a few tablespoons of vanilla extract. Run it for a few minutes, then wipe.
How often should I deep clean my microwave?
It depends on how much you use it. For most households, a deep clean like this once a month is sufficient. If you use it heavily, you might need to do it every two weeks.
Is it safe to use lemon juice instead of vinegar?
Yes, lemon juice is a great natural alternative. It has citric acid that cuts grease and leaves a pleasant, fresh scent. Vinegar might be slightly more effective on tough grease, but both are excellent choices.
Can I clean the microwave without vinegar?
Absolutely. You can use just water for the steam step, though grease may not break down as easily. A drop of dish soap in the water bowl can help, or use the lemon method described above.
A clean microwave is more hygienic, works better, and makes your whole kitchen feel fresher. By following these simple deep cleaning steps, you can tackle even the toughest messes with confidence. Just remember the power of steam, use gentle tools, and a little regular upkeep will keep it sparkling between big cleans.
