How to Clean the Inside of a Microwave

Microwaves accumulate splattered food, grease, and odour-causing residue inside the cavity. Most cleaning attempts involve hard scrubbing at dried-on splatter. The steam method almost completely eliminates the need to scrub.

The Steam Method (Takes 10 Minutes, No Scrubbing)

  1. Fill a microwave-safe bowl with 1 cup of water and add 2 tablespoons of white vinegar (the vinegar helps deodorize and adds cleaning power)
  2. Place a wooden toothpick or chopstick in the bowl — this prevents superheating by giving bubbles a nucleation point
  3. Microwave on high for 5 minutes — the water will boil and fill the microwave cavity with steam
  4. Do not open the door immediately — leave the door closed for 3 minutes to allow the steam to continue working and condensing on all interior surfaces
  5. Carefully remove the bowl (it will be very hot — use oven mitts) and wipe the inside with a damp cloth or sponge. Everything should wipe off easily without scrubbing — the steam has softened all the dried splatter.
  6. Remove the turntable plate and wash it separately in the sink with soapy water
  7. Wipe the door, door seal, and control panel with a damp cloth

For Stubborn Stains After Steaming

If anything doesn't wipe off easily after steaming:

  • Apply a small amount of baking soda paste (baking soda mixed with a little water) directly to the stain
  • Let sit 5 minutes
  • Scrub with a damp cloth — baking soda is mildly abrasive without scratching

Deodorizing a Smelly Microwave

  • After cleaning, place a small bowl of baking soda inside the microwave overnight (without running it) — this absorbs lingering odours
  • For strong odours like fish or burnt food: microwave a bowl of water with lemon slices or a few drops of vanilla extract for 3 minutes

How Often

  • Wipe exterior and interior weekly or whenever visible splatter appears
  • Full steam clean: monthly
  • Wash turntable plate: weekly
