You open the microwave door to reheat lunch, and a wave of old fish or burnt popcorn hits you. Gross. We rely on our microwaves daily, but those lingering odors can ruin your appetite fast.
If your appliance smells funky, don’t worry. We have the solution. You don’t need harsh chemicals or expensive cleaners to fix this.
Follow our guide on how to get smells out of a microwave. You will banish bad odors and loosen stuck-on grime in just a few minutes.
Key Takeaways
- Steam clean: Microwave a mixture of water and vinegar for 90 seconds, then let it sit for three minutes to loosen grime and neutralize odors.
- Absorb lingering smells: Leave a bowl of baking soda or activated charcoal inside the unit overnight to soak up stubborn stenches.
- Mask with scents: Use vanilla extract, citrus slices, or cloves to replace bad odors with a pleasant aroma.
- Prevent buildup: Always cover food to prevent splatters and wipe down the interior immediately after spills occur.
Why Does My Microwave Smell?
Microwaves trap moisture and heat, creating the perfect environment for odors. When you heat food, liquid evaporates and splatters onto the ceiling, walls, and glass plate. If you don’t wipe this residue away immediately, it cooks onto the surface every time you use the appliance.
Certain foods are repeat offenders. Fish, bacon, and popcorn contain strong oils and proteins that leave distinct odors.
Burnt food is another culprit. If you overcook a bag of popcorn, those carbonized particles stick to the fan and vents.
Mold can also be an issue. If you leave the door closed after steaming veggies, trapped moisture can lead to mildew growth.
Warning: If your microwave smells like burning plastic or hot copper, unplug it immediately. This usually indicates an electrical fault or burnt wiring. Do not use the appliance until a professional checks it.
How To Get Smells Out of a Microwave With Vinegar
Vinegar is the ultimate odor neutralizer. The acetic acid cuts through grease and kills bacteria. We love this method because the steam does the hard work for you.
- Time: 10 to 15 minutes.
- Difficulty: Easy.
What You’ll Need
- Microwave-safe bowl or cup.
- Distilled white vinegar.
- Water.
- Microfiber cloth.
- Spoon.
- Baking soda (optional).
- Lemon juice (optional).
1. Mix Your Solution
Grab a microwave-safe cup or bowl. Mix roughly half a cup of water with three tablespoons of distilled white vinegar. Give it a quick stir.
Try This
If the smell of vinegar bothers you, add a tablespoon of lemon juice to the mixture.
2. Create Steam
Place the cup in the center of the microwave. High heat usually works best. Set the timer for 90 seconds to two minutes. Watch the cup; you want the water to boil and create steam, but you do not want it to explode over the sides.
3. Let It Sit
This is the most important step. Do not open the door yet. Let the steamy mixture sit inside for at least three minutes. The steam loosens dried food splatters and neutralizes the smell in the vents.
4. Wipe It Down
Open the door carefully. The cup will be hot, so use an oven mitt to remove it. Dip your microfiber cloth into the remaining hot liquid (be careful) or fresh warm water. Wipe down the ceiling, walls, door, and turntable. The grime should slide right off.
5. The Overnight Trick
If a faint odor remains, pour a fresh cup of baking soda into a bowl. Place it in the microwave and shut the door. Leave it overnight. Baking soda is highly absorbent and will soak up the remaining smell molecules without any extra scrubbing.
6. Rinse and Repeat
For severe cases, like burnt popcorn, you may need to repeat the steaming process twice.
How To Deodorize a Microwave Naturally
If you are out of vinegar, or you just hate the smell, you have other options. Nature provides plenty of powerful deodorizers.
With Coffee Grounds
Coffee contains nitrogen, which helps neutralize odors rather than just masking them. It’s a great way to use up grounds from your morning brew.
- Mix: Combine two tablespoons of coffee grounds with half a cup of water in a microwave-safe bowl.
- Heat: Microwave for three minutes. Watch to ensure it doesn’t boil over.
- Steam: Let it sit for one minute, then remove the bowl.
- Wipe: Wipe up the condensation with a clean cloth. Your kitchen will smell like a fresh roast.
With Vanilla Extract
This method is perfect if you want your kitchen to smell like a bakery. It works well to mask mild odors.
- Pour: Add three teaspoons of vanilla extract to a small, shallow bowl.
- Heat: Microwave on high for 30 seconds. Keep an eye on it so it doesn’t bubble over.
- Enjoy: Remove the bowl. The pleasant aroma should linger for hours.
Note: Use real vanilla extract for the best results. Artificial flavorings may smell chemical when heated.
Warning
Stop the microwave immediately if you hear sizzling or popping. Burning the vanilla will only make the smell worse.
With Charcoal
Activated charcoal is a powerhouse for absorption. It pulls moisture and odors out of the air.
- Prep: Buy activated charcoal bags or cut up standard charcoal briquettes (without lighter fluid) and place them in a bowl.
- Place: Put the bowl inside the microwave. Do not turn the microwave on.
- Wait: Leave it overnight or for 24 hours.
- Test: Open the door and sniff. If the smell is gone, remove the charcoal.
With Cloves
Cloves contain eugenol, a compound with antiseptic and aromatic properties. This is a spicy, warm way to handle odors.
- Fill: Pour 1/4 cup of whole cloves into a bowl.
- Sit: Place the bowl in the microwave and leave it overnight. Do not turn the microwave on.
- Reuse: You can keep this bowl on the counter and pop it back in the microwave whenever not in use to maintain freshness.
With Berries
If you want a fruity scent, try mixed berries. This effectively masks smells but does not deep clean.
- Fill: Place a handful of mixed berries in a bowl.
- Cover: Cover tightly with microwave-safe plastic wrap. Ensure the berries do not touch the plastic.
- Heat: Microwave for one to two minutes.
- Vent: Carefully peel back the plastic (watch out for steam burns) and discard the fruit. Do not eat it; the plastic may have melted slightly.
With Citrus Fruit
Lemons, limes, and oranges contain limonene, a natural solvent and fragrance. This works similarly to the vinegar method but smells much better.
- Slice: Cut two lemons or oranges into halves or thick slices.
- Water: Place the fruit in a bowl and fill with water until the fruit is mostly submerged.
- Heat: Microwave for three minutes until the water boils.
- Steam: Let it sit for five minutes. The citrus steam will cut through grease on the walls.
- Clean: Dip a sponge into the warm citrus water and use it to scrub the interior.
Tips For Preventing Bad Smells in a Microwave
Prevention is always easier than the cure. Keep your appliance fresh with these simple habits.
- Use a Splatter Cover: This is the number one rule. Buy a plastic microwave cover or use a paper towel over your food. It prevents sauce from exploding onto the ceiling of the unit.
- Wipe Spills Immediately: If something boils over, don’t let it dry. Wipe it up while it is still warm and liquid.
- Air It Out: Leave the microwave door slightly ajar for 10 minutes after cooking steaming foods. This allows moisture to escape and prevents mold.
- The Baking Soda Guard: Keep a small open box of baking soda in the microwave when you aren’t using it. Just remember to take it out before you heat your lunch!
- Clean the Gasket: grime often hides in the rubber seal around the door. Wipe this down with a damp cloth weekly.
