Everyone has opened a microwave and found a crime scene. Exploded soup, splattered sauce, a mystery smell from last week’s fish. The good news: knowing how to clean a microwave is mostly about steam, not elbow grease. Five minutes, a bowl of water and a cloth are all you need.

Here’s the simplest method, plus a few tricks for the stubborn bits.
How to clean a microwave: the short answer
Heat a microwave-safe bowl of water (with a few lemon slices or a splash of white vinegar, if you like) for a few minutes until it steams up the inside. Leave the door closed for another few minutes, then carefully remove the bowl and wipe everything down. The steam loosens dried-on food so it wipes off easily.
6 easy steps
- Fill a bowl. About a cup of water in a microwave-safe bowl. Add lemon slices or a tablespoon of vinegar for smells.
- Add a wooden stick or spoon. A microwave-safe wooden utensil in the water helps prevent superheated water from boiling over suddenly.
- Heat for 3 to 5 minutes. Until the window fogs up.
- Wait 3 to 5 minutes. Keep the door closed so the steam works.
- Remove carefully. The bowl will be hot. Use oven mitts.
- Wipe it down. Take out the turntable and wipe the walls, ceiling and floor with a damp cloth.
Lemon, vinegar or plain water?
| Option | Best for | Note |
|---|---|---|
| Plain water | Light splatters | Works fine for weekly cleaning |
| Lemon slices | Smells and a fresh scent | Gentle and pleasant |
| White vinegar | Greasy buildup and stubborn odors | The smell fades quickly |
| Mild dish soap on a cloth | Spots left after steaming | Wipe with clean water afterward |
Don’t forget the rest
- Turntable: wash it in warm soapy water or check if it’s dishwasher safe.
- Door and seal: food on the seal can stop the door closing properly. Wipe it gently.
- Keypad: spray cleaner on the cloth, not the keypad.
- Vents: if you have an over-the-range model, its grease filters need washing too. Check the manual.
Stubborn smells
If a smell lingers after cleaning, leave the door open for a while to air out. A small bowl of baking soda left inside overnight (with the microwave off) can help absorb odors. Burnt popcorn is the worst offender; you might need a couple of rounds of the vinegar steam method.
Keep it clean with one habit
Cover your food. A microwave-safe cover or a paper towel stops most splatters before they happen, and it helps food heat more evenly too. Wipe up spills while they’re fresh and you’ll rarely need a deep clean. If you’re cleaning other gadgets this weekend, see how to clean a coffee maker next.
A quick routine that keeps it fresh
If you use the microwave every day, a tiny routine beats a big cleaning session. Wipe the turntable and door seal once a week while you wait for your coffee. Do the steam clean every few weeks, or right after a big spill. Keep a dedicated microwave cover next to the machine so it actually gets used. And leave the door open for a few minutes after reheating something strong, like fish or curry, so the smell doesn’t settle in. That’s it: a couple of minutes a week, and you’ll never face a crusty microwave again.
Safety notes
Never run the microwave empty, and never put metal, foil or dishes with metallic trim inside. Unplug it before cleaning the vents or anything near electrical parts. If the inside paint is peeling or the door doesn’t close properly, stop using it and contact the manufacturer or a repair technician.
Quick FAQ
How often should I clean my microwave? A quick wipe weekly and a steam clean every few weeks works for most homes.
Is vinegar safe for microwaves? Diluted in water and heated in a microwave-safe bowl, it’s a common, gentle method.
Can I use bleach? It’s best to avoid harsh chemicals inside food appliances. Mild dish soap is enough.
How to clean a microwave: a quick recap
- Steam: bowl of water, a few minutes on high.
- Wait: let the steam soften the mess.
- Wipe: walls, ceiling, turntable and door seal.
- Prevent: cover food every time.
