How to Clean the Inside of a Microwave
Microwave interiors accumulate baked-on food splatter from uncovered dishes — the food dries and hardens onto the ceiling, walls, and floor of the cavity, often with layers from multiple incidents. Scrubbing directly at dried food particles is ineffective and can damage the interior surface. The steam method softens everything first, making it easy to wipe away.
The Steam Method (5–10 Minutes)
- Fill a microwave-safe bowl with 1 cup of water and add 1 tablespoon of white vinegar (the vinegar helps deodorize and adds cleaning power)
- Place a wooden toothpick in the bowl to prevent superheating — this is a safety precaution
- Microwave on high for 2–3 minutes, until the water boils and the inside of the microwave is steamed up
- Leave the door closed for 3 minutes after stopping — the steam continues working and the heat is retained, softening everything inside
- Remove the bowl carefully with oven mitts or a towel (it will be hot)
- Remove the turntable plate and wipe down with a damp cloth — the softened food wipes away easily
- Wipe all interior surfaces (ceiling, walls, floor) with a damp cloth — most food should come off without scrubbing
- For stubborn spots, dip the cloth in the vinegar water and rub
- Wash the turntable in the sink and dry before replacing
The Door Seal and Exterior
- Wipe the door seal (the rubber gasket) with a damp cloth — grease accumulates there
- Clean the exterior panel and handle with a damp cloth and mild dish soap
- For stainless steel exteriors, wipe in the direction of the grain and dry to prevent streaks
