Key Takeaways
- Steam does the work; scrubbing is the failure mode. Heat water inside the appliance, let the steam soften the grease, then wipe — one method covers the oven, the microwave and the air fryer.
- Most Singapore kitchens have a countertop oven or air fryer, not a built-in wall oven with a self-clean cycle — so the advice has to work without one.
- Start with the microwave. It takes five minutes, and it proves the method before you try it on the oven.
- Never use oven cleaner in an air fryer. Caustic cleaner strips the non-stick coating, and that coating does not come back.
- Never mix bleach with vinegar or ammonia, and never spray any liquid onto a heating element. Unplug the appliance and let it cool before you clean inside it.
It’s Sunday afternoon in a Sengkang flat and the oven door has gone from glass to amber. The air fryer smells of last Tuesday’s chicken wings every time you switch it on, and the microwave roof has spots you stopped seeing months ago. None of it is urgent, which is exactly why it keeps getting put off.
You don’t need to scrub. You need about ten minutes of steam.
What Is the Easiest Way to Clean an Oven, Microwave or Air Fryer?
Heating a bowl of water inside an oven or microwave for ten minutes softens baked-on grease with steam, so it wipes away without scrubbing or caustic cleaner. Warm moisture gets under cold, dry grease and loosens its grip; a damp cloth does the rest.
The same principle works on all three. Do them in order of effort — microwave, then air fryer, then oven — so the quick win comes first.
How Do You Clean a Microwave?
Microwave a bowl of water with lemon or vinegar for three to five minutes, leave the door shut for five more, then wipe.
- Fill a microwave-safe bowl about halfway with water. Squeeze in half a lemon, or add a tablespoon of white vinegar.
- Put a wooden chopstick or spoon in the bowl. It stops the water boiling over suddenly.
- Heat on high for three to five minutes, until the window steams up.
- Keep the door closed for another five minutes. This is where the steam does the work.
- Take the bowl out carefully — it will be hot — and remove the turntable to wash in the sink.
- Wipe the walls, the roof and the inside of the door with a damp microfibre cloth. The roof is where most of the splatter lives.
Anything still stuck gets a second two-minute round. If a smell stays after cleaning, leave an open bowl of baking soda inside with the door closed overnight.
How Do You Clean an Air Fryer?
Wash the basket after every use, and deal with the inside and the heating element separately and gently. Its non-stick coating is the easiest thing in the kitchen to damage.
- Unplug it and let it cool completely. Never clean an air fryer that’s still warm.
- Soak the basket and tray in warm, soapy water for 15–20 minutes. Stuck-on bits then come off with a soft sponge.
- For burnt-on grease in the basket, spread a paste of baking soda and a little water, leave it for 15 minutes, and wipe it off with the soft side of a sponge.
- Wipe the inside of the main unit with a damp cloth and a drop of dish soap.
- Turn the unit upside down to reach the heating element. Brush it gently with a soft, dry brush — an old toothbrush works — to remove grease and crumbs. Don’t spray or pour anything on it.
- Let everything dry fully before you put it back together.
No metal scourers, no steel wool, no oven cleaner. Once the coating is scratched or stripped, food sticks, and the flaking coating ends up in your food.
How Do You Clean an Oven Without Scrubbing?
Steam it, wipe it, then use baking soda paste on whatever is left. Here’s how that works on a countertop oven or a built-in one:
- Take the racks and tray out. Soak them in the sink in hot water with dish soap while you work on the inside.
- Put an oven-safe dish of water on the middle rack position (or the oven floor on a countertop model), with a squeeze of lemon or a splash of vinegar.
- Heat to around 120°C for 20 minutes.
- Turn the oven off and let it cool until it’s warm, not hot. Unplug a countertop oven.
- Wipe the walls, floor, roof and the inside of the door glass with a damp microfibre cloth. Most of the grease should come away.
- For stubborn patches, mix baking soda with a little water into a spreadable paste. Coat the patches — keep it off the heating elements — and leave it for a few hours or overnight.
- Wipe the paste off with a damp cloth. Spray a little vinegar on any white residue to lift it, then wipe again.
- Scrub the soaked racks with a sponge, rinse and dry.
Should You Use Oven Cleaner?
Only in a traditional enamel oven, with the kitchen well ventilated — never in an air fryer, a microwave or a coated oven. Commercial oven cleaners are strongly alkaline: fast on thick carbon, but harsh on skin and eyes, and slow to clear from an enclosed HDB kitchen. If you use one, wear gloves, open the windows, run the hood fan and keep it off heating elements and rubber seals. For most countertop ovens, steam and paste get you close enough without the risk.
Never mix bleach with vinegar or ammonia — each combination produces a toxic gas. And never spray any cleaning liquid directly onto a heating element.
When Is It Past a DIY Clean?
When the grease has turned into a hard, black crust that survives both a steam round and an overnight baking soda paste. At that point you’re scraping, and scraping is where people scratch door glass and damage enamel.
Urban Company’s Interior Oven Cleaning is a 30-minute professional clean of the oven’s interior at S$49. If the whole kitchen needs it — the hob, the backsplash and the grease that has spread past the oven — see Kitchen Deep Cleaning and book in Singapore, which uses high-temperature steam and heavy-duty scrubbing across the room.

Frequently Asked Questions
How do you clean an oven without oven cleaner?
Put an oven-safe dish of water, with a squeeze of lemon or a spoon of vinegar, on the middle rack and heat the oven to around 120°C for 20 minutes. Let it cool until it is warm, not hot, then wipe the softened grease away with a damp microfibre cloth. A paste of baking soda and water handles whatever the steam leaves behind.
Does the steam-and-wipe method actually work on baked-on grease?
On grease that has built up over weeks, yes — steam softens it enough to wipe off. On carbonised black crust that has been baked on for years, steam loosens the top layer but not all of it. Do one steam round, wipe, then use a baking soda paste left overnight on the stubborn patches.
Can you put an air fryer basket in the dishwasher?
Many baskets are labelled dishwasher-safe, but check your manual first. Even when they are, hand-washing with warm soapy water and a soft sponge is kinder to the non-stick coating, which dishwasher detergent wears down over time. Never use a metal scourer or oven cleaner on the basket.
How do you get the smell out of a microwave?
Microwave a bowl of water with half a lemon squeezed into it on high for three to five minutes, then leave the door closed for five more so the steam can work. Wipe the inside down, including the roof and the door seal. For a lingering smell, leave an open bowl of baking soda inside overnight.
How often should an oven be cleaned?
Wipe up spills once the oven has cooled after each use, and do a full steam-and-wipe clean every three months if you use it a few times a week. Air fryers need the basket washed after every use and the inside wiped weekly, because grease builds up close to the heating element.
What does professional oven cleaning include?
Urban Company’s Interior Oven Cleaning is a 30-minute professional clean of the oven’s interior, at S$49. For grease that has spread across the whole kitchen, Kitchen Deep Cleaning is a separate service that uses high-temperature steam and heavy-duty scrubbing.
