No scrubbing, no chemicals: a bowl of lemon water boiled in the microwave steams every crusted splatter loose, and the whole job is done inside ten minutes.

Fill a microwave-safe bowl with about 250ml (a cup) of water, squeeze in half a lemon and drop the squeezed half in too. Run the microwave on high for three to five minutes until the window fogs and the water boils hard. Then - the step that matters - leave the door closed for five more minutes.
Those closed-door minutes are the cleaning. The trapped steam condenses onto every surface and soaks into the dried splatter, doing the work your sponge would otherwise do. Open the door and everything wipes off with a single pass of a damp cloth, including the brown constellation that has been on the ceiling since lasagna night.
Dried food splatter is mostly dehydrated starch, fat, and sugar bonded to the enamel. Steam rehydrates it, and the lemon's mild acid helps cut the grease film while deodorizing - the citrus oil in the peel is doing real work, which is why the spent half goes into the bowl.
No lemon? Two tablespoons of white vinegar in the water works identically and is slightly stronger on grease; the smell vanishes as it dries. Plain water steams fine too - the acid is an upgrade, not a requirement. Skip the harsh sprays entirely: you are cleaning a box that food cooks in, and steam plus a cloth genuinely suffices.
Lift out the glass turntable and its roller ring and wash them in the sink with dish soap - they collect a film the steam treatment loosens but cannot rinse. While they dry, wipe the cavity: ceiling first (drips fall), then walls, then floor.
The spot everyone misses: the door seal and hinge channel. Food vapor condenses into the rubber gasket and the groove below the door, and it is the source of most mystery microwave smells. Run a damp cloth around the full seal and into the groove - the cloth will come back brown the first time, proving the point.
Use a bowl, never a sealed container or a smooth cup. Water microwaved in a very smooth vessel can superheat - exceed boiling without bubbling - and flash-boil when moved. The lemon in the water prevents this by giving bubbles a place to form, which is a second job that lemon is quietly doing.
Let the bowl sit for a minute before lifting it out, use a dry cloth on the hot bowl, and tip steam away from your face when opening the door. The steam that cleans the splatter scalds skin just as effectively.
Cover food. A vented microwave cover or even a paper towel over the plate prevents 95 percent of splatter, which is the entire reason microwaves get filthy. The cover takes one second per use; the steam clean takes ten minutes per month. Cheap insurance.
Wipe spills while they are fresh and still soft - a five-second swipe beats next month's archaeology. With a cover and the fresh-spill habit, the full steam treatment becomes a quarterly event instead of a monthly penance.
Three to five minutes on high - long enough for a hard boil and a fogged window - then five minutes with the door closed. Underboiling is the usual reason the trick 'didn't work'; the cavity needs to fill with steam.
Mostly yes, especially with lemon or vinegar in the water. For a stubborn smell (burnt popcorn is the classic), also clean the door seal and leave the door open for a few hours with a small bowl of baking soda inside overnight.
Identical method - steam, wait, wipe. The flatbed base wipes in place instead of going to the sink. Check the manual's cleaning page only if your model has a catalytic or self-clean liner, which shouldn't be scrubbed with anything abrasive.
The outside just needs a damp microfiber cloth with a drop of dish soap, especially the handle and keypad - the greasiest 20 square centimeters in most kitchens. Spray cleaner onto the cloth, not the keypad, to keep liquid out of the electronics.
