Cleaning & care
Cleaning and caring for a microwave
A microwave does its best work when the interior, the turntable and the door seal are clean. Baked-on splatter absorbs energy that should be heating your food, and a poorly sealing door is the one fault worth treating as more than cosmetic. None of the routine care needs tools.
The steam method for baked-on splatter
Heat loosens dried food far more effectively than scrubbing. The widely used approach is simple and uses only water.
- Fill a microwave-safe bowl with about a cup of water. A slice of lemon helps with odour but is optional.
- Heat until it boils and the window fogs — roughly two to three minutes depending on the unit’s power.
- Leave the door shut for a few minutes so the steam settles on the walls and ceiling.
- Wipe down with a damp cloth. Softened residue lifts without abrasive pads.
Turntable and roller ring
Lift out the glass tray and the roller ring underneath; both are usually dishwasher-safe or wash by hand. Food trapped under the ring is a common cause of uneven turning.
The door seal matters most
The mesh in the door window and the frame around it form the barrier that keeps energy inside the cavity. Wipe the seal and frame gently and keep them free of crumbs and grease. If the door is visibly damaged, does not latch firmly, or the mesh screen is torn, stop using the oven and have it checked — this is a safety matter, not a cleaning one.
Smells and sparks
- Lingering odours respond to the lemon-water steam above, repeated once or twice.
- Arcing or sparks often come from metal trim on dishes or from a worn waveguide cover. Remove metal first; if sparking continues with plain food, stop and have it serviced.
Everyday habits

Never run it empty
Operating a microwave with nothing inside can damage the magnetron. Keep a cup of water in the cavity if you want to test that it powers on.
