Microwave interiors accumulate splattered food on the walls, ceiling, and turntable that hardens when repeatedly heated. Many people are reluctant to spray commercial cleaners inside a food appliance. Here are effective chemical-free methods that work better than dry scrubbing anyway.
Method 1: Water and Vinegar Steam (Easiest)
- Fill a microwave-safe bowl or mug with 250ml (1 cup) of water and 2–3 tablespoons of white vinegar
- Place a toothpick or wooden skewer in the water to prevent superheating
- Microwave on high for 5 minutes — the water will boil and steam will fill the interior, loosening dried-on food
- Leave the door closed for another 2–3 minutes after the microwave stops — the trapped steam continues working
- Carefully remove the bowl (it will be hot)
- Remove the turntable and wash it in the sink
- Wipe the interior walls, ceiling, and floor with a damp cloth — the food residue will come off with minimal scrubbing
The vinegar smell dissipates quickly. The steam does the work; the scrubbing becomes easy.
Method 2: Lemon Steam
Works identically to the vinegar method but leaves a fresher smell:
- Slice a lemon in half, squeeze the juice into a bowl of water, and add the lemon halves to the bowl
- Microwave on high for 3 minutes
- Let sit with door closed for 5 minutes
- Wipe clean
Stubborn Spots After Steaming
For spots that remain after steaming: make a paste of baking soda and water, apply with a damp cloth, let sit 2 minutes, then wipe. This is mildly abrasive and handles residual hardened spots without scratching the microwave interior.
The Turntable
The glass turntable is usually dishwasher-safe (check your manual). Alternatively, wash in the sink with dish soap. Remove it from the oven before cleaning the interior so you can wipe beneath it.
The Exterior
Wipe the exterior with a damp microfibre cloth. The control panel should be wiped with a barely-damp cloth — avoid excess moisture near buttons and vents.
How Often
- Quick wipe after any spill or splatter: immediately
- Steam clean: monthly, or whenever the interior has visible buildup
