How to Clean the Inside of a Microwave
Microwave interiors accumulate splattered food that bakes onto the walls and ceiling from the heat of repeated use. The easiest approach uses steam to loosen the dried-on splatter before wiping — this requires almost no scrubbing.
The Steam Method (5 Minutes)
- Place a microwave-safe bowl filled with 1 cup of water and 1–2 tablespoons of white vinegar (or lemon juice) in the microwave
- Microwave on high for 5 minutes — the water boils and steam fills the microwave interior, loosening splattered food
- Allow the bowl to sit inside (do not open) for another 2–3 minutes — the steam continues working
- Remove the bowl carefully (it will be very hot — use oven mitts)
- Remove the turntable plate and wash it in the sink with dish soap
- Wipe the interior walls, ceiling, and floor with a damp cloth — the softened food should wipe off easily with no scrubbing
- For any remaining stubborn spots: apply a small amount of dish soap to a damp cloth and spot-clean
- Wipe dry with a clean cloth and replace the turntable
Lemon Variation
- Halve a lemon and place cut-side down in a bowl of water
- Microwave 5 minutes — the citric acid in lemon juice cuts grease slightly better than plain water or vinegar, and leaves a fresh scent
Exterior Cleaning
- Wipe the door, exterior panels, and control panel with an all-purpose cleaner on a cloth
- Use a damp cloth to remove cleaner residue — do not spray cleaners directly onto the control panel as moisture can damage electronic components
- Clean the door seal with a damp cloth — food trapped in the seal seal can cause odours
Frequency
A weekly steam clean (even just 2 minutes with water) prevents the heavy buildup that makes microwave cleaning a significant task. Covering food with a microwave-safe cover while cooking eliminates most splatter before it happens.
