How to Clean a Microwave in 5 Minutes with Lemon or Vinegar

Cleaning a microwave sounds like a scrubbing job, but it doesn't have to be. With a bowl of water and a little lemon or vinegar, steam does almost all the work for you. Dried-on splatters soften in minutes and wipe right off.

What You'll Need

A microwave-safe bowl
1 cup of water
1 lemon (sliced or juiced) or 2 tablespoons of white vinegar
A microfiber cloth or sponge
Dish soap (for the turntable)

Step 1: Make the Steam Bowl

Fill a microwave-safe bowl with 1 cup of water. Add lemon juice and the squeezed lemon halves, or 2 tablespoons of white vinegar. Lemon leaves a fresher smell, while vinegar is slightly better at cutting grease.

Place a wooden toothpick or spoon in the bowl. This gives the water something to bubble around and helps prevent it from boiling over suddenly.

Step 2: Heat Until Steamy

Microwave on high for 3–5 minutes, until the water boils and the window fogs up.

Step 3: Let It Sit

Don't open the door yet. Leave it closed for 2–3 minutes. The trapped steam softens the dried food on the walls and ceiling.

Step 4: Remove the Bowl Carefully

The bowl and water will be very hot. Use oven mitts to take it out.

Step 5: Wipe Everything Down

Remove the turntable. Wipe the ceiling first, then the walls, the door and the floor of the microwave. The splatters should come off easily. Dip your cloth in the warm lemon or vinegar water for any stubborn spots.

Step 6: Wash the Turntable

Wash the glass turntable and the roller ring in warm soapy water, dry them, and put them back.

For Stubborn Stains

Make a paste of baking soda and water, apply it to the spot, let it sit for 5 minutes, then wipe off with a damp cloth. Avoid steel wool and harsh scrubbers, which can damage the interior coating.

How to Get Rid of Microwave Smells

After cleaning, leave a small bowl of baking soda inside overnight with the door closed.
For burnt popcorn smells, repeat the steam method with lemon and leave the door open afterward to air out.

Clean the Outside Too

Wipe the handle and keypad with a damp cloth and a drop of dish soap. Don't spray liquid directly on the keypad, since moisture can get inside the controls.

How to Keep Your Microwave Clean

Cover food with a microwave-safe cover or a paper towel.
Wipe spills right away, while they're still easy to clean.
Do a quick steam clean once a week if you use your microwave often.
