Splatters, dried sauce and lingering smells build up fast in a microwave. The easiest way to clean it does not involve harsh sprays. A bowl of water with lemon or vinegar creates steam that softens grime so you can wipe it away. The whole job takes about ten minutes.
What you need
- A microwave-safe bowl or large measuring cup
- About 1 cup of water
- 1 lemon (sliced or juiced) or about 1 tablespoon of white vinegar
- A wooden spoon or toothpick (optional, see step 2)
- A soft sponge or microfiber cloth
- Mild dish soap for the turntable
Step-by-step: the steam method
- Mix the cleaning solution. Add about 1 cup of water to a microwave-safe bowl. Squeeze in lemon juice and drop in the halves, or add a tablespoon of white vinegar.
- Prevent boil-over. Placing a wooden spoon or toothpick in the bowl can help keep the water from superheating and bubbling over suddenly.
- Heat until steamy. Microwave on high for about 3 to 5 minutes, until the water boils and the window fogs up.
- Let it sit. Keep the door closed for another 3 to 5 minutes. The steam keeps working on dried-on food.
- Remove the bowl carefully. It will be very hot. Use oven mitts.
- Wipe the inside. Take out the turntable, then wipe the ceiling, walls and floor with a damp sponge or cloth. Most grime will come off easily.
- Wash the turntable. Clean it in warm, soapy water, or check your manual to see if it is dishwasher-safe. Dry it before putting it back.
- Clean the outside. Wipe the door, handle and control panel with a slightly damp cloth. Avoid spraying liquid directly onto the controls.
Lemon or vinegar: which is better?
Both work well. Lemon leaves a fresh scent and is a good choice if you dislike the smell of vinegar. Vinegar is cheap and great for greasy buildup, but the smell lingers for a few minutes. Either way, the steam does most of the work.
For tough stains
If spots remain after steaming, make a paste of baking soda and a little water. Apply it to the stain, let it sit a few minutes, and wipe with a damp cloth. Avoid steel wool and abrasive scouring pads, which can scratch the interior.
For lingering odors
After cleaning, leave the door open for a while to air out. An open bowl of baking soda left inside overnight (with the microwave off) can help absorb stubborn smells.
Safety tips
- Always use a microwave-safe container, never metal.
- Never run the microwave empty.
- Unplug the microwave before deep cleaning around the vents or door seal.
- Follow the cleaning instructions in your microwave’s manual.
How to keep it clean longer
- Cover food with a microwave-safe cover or a paper towel to catch splatters.
- Wipe up spills right away, while they are still soft.
- Do a quick steam clean once a week if you use your microwave daily.
Frequently asked questions
How often should I clean my microwave?
A quick wipe after spills and a steam clean about once a week works for most households.
Can I use bleach to clean a microwave?
It’s better to avoid strong chemicals inside a microwave. Steam with lemon or vinegar plus mild dish soap is enough for routine cleaning.
Why does my microwave still smell after cleaning?
Odors can linger in vents and seals. Air it out with the door open and try a bowl of baking soda overnight.
The bottom line
