How to Clean a Microwave in 5 Minutes

If your microwave looks like a crime scene from last week’s spaghetti sauce explosion, you don’t need to scrub for an hour. There’s a trick that does 90% of the work for you: steam.

By microwaving water with lemon or vinegar, you create steam that softens every bit of grease, cheese, and dried food inside. After that, a quick wipe is all it takes.

The Steam Cleaning Method

This is the fastest, easiest way to clean any microwave.

What you’ll need:

  • 1 cup of water
  • 2 tablespoons of white vinegar OR juice from half a lemon
  • A microwave-safe bowl
  • A damp cloth or sponge

Step 1: Make the Steam

  1. Fill a microwave-safe bowl with 1 cup of water.
  2. Add vinegar or lemon juice. Both work — lemon smells better, vinegar is slightly more effective on grease.
  3. Place the bowl in the center of the microwave.

Step 2: Steam It Up

  1. Microwave on high for 3-5 minutes. You want the window to be completely fogged with steam.
  2. Don’t open the door when it beeps. Let it sit for another 2-3 minutes with the door closed. This is when the steam does its best work — loosening all the stuck-on food.

Step 3: Wipe Clean

  1. Carefully remove the bowl — the water will be very hot.
  2. Wipe the interior with a damp cloth or sponge. Everything should come off effortlessly.
  3. Pay special attention to corners and the ceiling of the microwave — these collect the most splatter.
  4. For stubborn spots, dip your cloth back in the hot lemon water and give them a quick scrub.

That’s it. Your microwave is clean.

How to Clean the Turntable

The glass turntable and roller ring can be washed separately:

  1. Remove the turntable and roller ring from the microwave.
  2. Wash in the sink with warm, soapy water, or put them in the dishwasher (check your manual).
  3. Dry completely before placing them back.

How to Clean the Exterior

  • Standard finish: Wipe with a damp cloth and mild dish soap.
  • Stainless steel: Wipe in the direction of the grain with a damp microfiber cloth, then dry immediately to prevent water spots.
  • Control panel: Spray a small amount of cleaner onto a cloth (never directly onto the panel) and wipe gently.

What NOT to Do

  • Don’t use bleach inside the microwave — it can damage the interior surface and leave harmful residues.
  • Don’t use abrasive scrubbers (steel wool, harsh brushes) — they scratch the interior coating.
  • Don’t spray cleaning products directly onto the microwave walls — always apply to a cloth first.
  • Don’t run the microwave empty — this can damage the magnetron.

Prevention Tips

  • Cover food with a microwave-safe lid or paper towel when heating to prevent splatter.
  • Wipe up spills immediately while they’re still wet — it takes 5 seconds versus 5 minutes later.
  • Do a quick steam clean weekly if you use the microwave daily — it prevents any buildup from forming.

The Bottom Line

The lemon or vinegar steam method is the single best trick for cleaning a microwave. It takes 5 minutes, requires no scrubbing, and costs almost nothing. Keep a lemon or vinegar handy, and your microwave will never get gross again.

Frequently Asked Questions

How do you clean a microwave naturally?

Fill a microwave-safe bowl with 1 cup of water and 2 tablespoons of vinegar or the juice of half a lemon. Microwave on high for 3-5 minutes until the window steams up. Let it sit for 2 minutes, then wipe clean with a damp cloth. The steam loosens all the grease and food splatter.

How do you get baked-on food out of a microwave?

For stubborn, dried-on food, use the steam method above but add 5 minutes of sitting time. The steam softens even old, baked-on food. For extra-tough spots, dip a sponge in the hot lemon water and scrub gently.

How often should I clean my microwave?

Clean your microwave every 1-2 weeks, or as soon as you notice food splatter. Fresh splatters wipe away easily in seconds, while old ones require more effort. A weekly quick-wipe prevents buildup.

Can I use baking soda to clean my microwave?

Yes. Make a paste of baking soda and water, apply it to stubborn stains, and let it sit for 5 minutes before wiping. However, the steam method (lemon or vinegar) is faster and requires less scrubbing.

How do you clean the outside of a microwave?

Wipe the exterior with a damp cloth and mild dish soap. For stainless steel microwaves, wipe in the direction of the grain with a damp microfiber cloth, then dry to prevent water spots.
