Key Takeaways
- The filter type decides the method. Aluminium mesh and stainless steel baffle filters are soaked and scrubbed; charcoal filters in recirculating hoods cannot be washed and must be replaced.
- A 15-minute soak in very hot water with dish soap and baking soda shifts most hood-filter grease. Never use caustic oven cleaner on aluminium — it darkens and pits the metal.
- Wok cooking means more frequent cleaning. If you stir-fry most days, clean the filter every two to four weeks, not every few months.
- Grease above a flame is a fire risk. Switch the hood off at the wall and turn the gas off before cleaning anything in the cooking zone.
- Cabinets and burners need gentler treatment: dish soap and baking soda for cabinet doors; burners dried completely before refitting.
It’s Sunday afternoon in your Tampines flat, and the hood has been roaring for a year without pulling out much smoke. The filter comes out brown and sticky enough to hold fingerprints, and so do the cabinet doors beside it. It’s all one problem: cooking oil that went up as vapour and came down as glue.
How Do You Clean a Kitchen Hood Filter?
Soak it in very hot water with dish soap and baking soda for about 15 minutes, then scrub it with a soft brush and rinse. That works for aluminium mesh and stainless steel baffle filters.
- Switch the hood off at the wall. Most filters release with a spring catch or pull tab.
- Fill the sink with the hottest water you have and stir in a good squeeze of dish soap and a few spoonfuls of baking soda.
- Submerge the filter and leave it for 15 minutes.
- Scrub along the mesh with a soft brush or old toothbrush.
- Rinse under hot running water until no suds remain, then let it dry completely before refitting.
After draining the soak water, run the hot tap for a minute so the grease doesn’t re-set in the pipe.
Which Hood Filter Do You Have, and How Should You Clean It?
Check the filter before you clean it: the wrong method can ruin it.
| Filter type | How to recognise it | How to clean it |
|---|---|---|
| Aluminium mesh | Light, layered silver mesh, flexes slightly | Hot soapy soak with baking soda. No caustic oven cleaner — it darkens and pits aluminium |
| Stainless steel baffle | Heavy, rigid, angled metal slats | Hot soak and scrub, or a hot dishwasher cycle if the manual allows. Tolerates a degreaser |
| Charcoal (carbon) | Black pad or cartridge behind the metal filter, in hoods that recirculate air | Do not wet it. Replace it, usually every few months |
A hood that blows air back into the kitchen rather than out through a duct has a charcoal filter behind the metal one.
How Do You Clean a Cooker Hood Itself?
Wipe it down with a well-wrung cloth, warm water and dish soap while the filters soak — including the underside around the filter frame, the part people skip. Never spray cleaner straight onto the hood; liquid can run into the light or motor housing. Wipe stainless steel along the grain and finish with a dry microfibre cloth.
If the stainless steel has orange spots or white marks rather than grease, that’s a different job with different cleaners: see how to clean rust and water marks off stainless steel.
How Often Should You Clean the Hood Filter in Singapore?
Every two to four weeks if you stir-fry most days; every two or three months for lighter cooking. A wok over a high flame puts far more oil into the air, and the filter catches it.
Unattended cooking has been one of the main causes of residential fires in Singapore, and a grease-soaked filter is fuel sitting directly over the flame.
How Do You Clean Grease Off Kitchen Cabinets?
Wipe the doors with a cloth wrung out in warm water and dish soap, then dry them straight away. That removes most of the film on cabinets beside and above the hob.
For the stubborn, tacky layer — usually on the cabinets flanking the hood and on top of the wall units — spread a paste of baking soda and a little water, leave it for a few minutes, then wipe it off with a soft cloth and dry.
Go easy on water with wood veneer and laminate, skip scourers on high-gloss doors, and test any degreaser inside a door first. With stronger products, open the window: NEA’s cleaning guidelines recommend ventilating the home during cleaning to reduce the concentration of cleaning products in the air.
How Do You Clean Gas Stove Burners?
Turn the gas off, let the hob cool, then lift off the burner caps and soak them in hot soapy water. SCDF’s fire safety advice is to turn off the gas supply and cooking appliances whenever they are not in use — and cleaning time counts.
- Lift off the pan supports, burner caps and burner heads.
- Soak them for 15 to 20 minutes in hot water with dish soap, then scrub with an old toothbrush.
- Clear blocked ports with a needle or straightened paper clip. Avoid toothpicks, which snap off inside.
- Wipe the hob surface around each burner, keeping water away from the ignition electrode.
- Dry every part completely before refitting. A wet burner lights unevenly or not at all.
A flame that burns yellow or orange after cleaning usually means a cap is crooked or a port is still blocked.
When Should You Leave It to a Professional?
Everything above is a fair DIY job. Anything involving the gas supply is not. If you smell gas, don’t touch light switches or light a flame — open the windows, leave the flat and call your gas supplier’s emergency line. Under HDB rules, gas service works must be carried out by an EMA-licensed gas service worker, so a hob that won’t stay lit or keeps burning yellow is their job, not a cleaner’s. A hood motor that has stopped working is an appliance repair.
The same degrease-first logic applies inside the oven and microwave, and a lingering smell that survives a clean kitchen is often coming from the fridge instead. A greasy kitchen is where a deep clean beats a regular one, and whether hiring help is worth it comes down to what your weekend is worth. If the grease has spread across the whole kitchen, Urban Company’s Kitchen Deep Cleaning starts from S$135 and uses high-temperature steam with heavy-duty scrubbing.
Frequently Asked Questions
How often should you clean a kitchen hood filter?
If you stir-fry most days, clean the filter every two to four weeks. Lighter cooking can stretch to every two or three months. The practical test is touch: if the mesh feels sticky or looks brown rather than silver, it is overdue, and the hood is already pulling less smoke than it should.
Can you put a hood filter in the dishwasher?
Most stainless steel baffle filters and many aluminium mesh filters are dishwasher-safe, but check the manual first. Run them on their own on a hot cycle, standing upright. Dishwasher detergent can dull aluminium over time, so a hot soak by hand keeps a mesh filter looking newer for longer.
Can you wash a charcoal hood filter?
No. Charcoal filters, found in hoods that recirculate air instead of venting outside, trap odour inside the carbon itself. Water and detergent ruin them. They are replaced, not cleaned — usually every few months, depending on how much you cook. The metal grease filter in front of the charcoal still gets washed as normal.
What dissolves kitchen grease best?
Very hot water with a good dish soap dissolves most fresh grease. For older, sticky layers, add baking soda to the soak or make a paste and leave it on for ten minutes. A kitchen degreaser is the next step up. Avoid caustic oven cleaner on aluminium, painted surfaces and wood.
Why is my gas stove flame yellow or orange?
A healthy gas flame burns mostly blue. Yellow or orange tips usually mean the burner ports are clogged with food or grease, or the burner cap is sitting crooked. Clean and dry the burner, refit the cap squarely, and check again. If the flame stays yellow, have the hob checked by a professional.
How do you get sticky grease off kitchen cabinets?
Wipe with a cloth wrung out in warm water and dish soap, then dry immediately. For the tacky film that builds up near the hob, spread a paste of baking soda and a little water, leave it a few minutes, and wipe off with a soft cloth. Test any degreaser on a hidden spot first.
