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)
- 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)
- Place a wooden toothpick or chopstick in the bowl — this prevents superheating by giving bubbles a nucleation point
- Microwave on high for 5 minutes — the water will boil and fill the microwave cavity with steam
- 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
- 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.
- Remove the turntable plate and wash it separately in the sink with soapy water
- 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
