Can I use only water to steam-clean the microwave?

Yes. Plain water is normally enough to soften light food splatters. Follow the microwave manufacturer's cleaning instructions, and wipe the surfaces with a soft cloth afterward.

How long should I heat the water?

There is no universal time. Microwave power, bowl shape and the water temperature vary. Heat in short intervals while watching for gentle steam, and stop before vigorous boiling; never leave it unattended.

What if dried-on stains remain?

Try a second gentle steam-and-wipe cycle after the water and bowl have cooled, or apply a little mild dish soap to a soft cloth. Avoid abrasive pads, sharp scrapers and spraying liquid into vents or controls.

Is it safe to clean the door seal and controls?

Gently wipe accessible seal surfaces with a barely damp cloth without pulling or scraping the seal. Do not spray the controls or let water enter vents. Stop using the appliance and seek service if the seal, latch or door is damaged.

Let the microwave cool and check it

Switch the microwave off and let its interior cool. Read the maker's cleaning advice. Do not use an appliance with a damaged door, seal or latch; arrange service instead. Take out loose accessories and the glass turntable and roller ring if your model allows it. Put them aside for washing once cool.

Switch the microwave off and let its interior cool. Read the maker's cleaning advice. Do not use an appliance with a damaged door, seal or latch; arrange service instead. Take out loose accessories and the glass turntable and roller ring if your model allows it. Put them aside for washing once cool.
2. Prepare an open bowl of water

Pour about 250 ml of clean water into a wide, open bowl clearly marked microwave-safe. Leave plenty of empty space above the water; never use a sealed container, metal vessel or an unsuitable cup. Place the bowl in the middle of the microwave. Plain water is enough to soften normal splatters. If you removed the glass turntable or roller ring earlier, refit both correctly before heating, as your model requires.
3. Warm the water gently until it steams

Heat the uncovered bowl in short intervals following the appliance manual, watching for visible steam. Stop before vigorous boiling; times vary with microwave power and the bowl. Never leave heating water unattended or disturb very hot water abruptly, as it can splash or superheat. If the water is not steaming, add another short interval rather than a long cycle.
4. Let the steam loosen splatters

When steam has formed, stop heating and keep the microwave door closed for about three to five minutes. This dwell time helps soften dried food. Open the door slowly with your face away from the rising steam. Let the bowl cool until it is safe to handle, then remove it with heat-resistant mitts; do not spill hot water.
5. Wipe the interior without soaking it

With the microwave switched off and the hot bowl removed, wipe the ceiling, walls, floor and inside of the door using a soft, slightly damp cloth. For a persistent spot, put a drop of mild dishwashing liquid on the cloth and rub gently, then wipe away the residue with a clean damp cloth. Do not scrape coatings, flood vents, spray the control panel or force-clean around the door seal.
6. Wash, dry and replace the removable parts

Wash the cooled glass turntable and roller ring according to the manufacturer's instructions; use warm soapy water when allowed, rinse and dry. Wipe remaining moisture from the microwave interior, especially around the door and seal, and allow it to air-dry with the door open. Reinstall the clean parts only when dry. If the door seal is damaged or a smell persists despite cleaning, consult the manual or a qualified technician.
