6 Ways How to Clean Extractor Fan (No Special Tools or Fuss)

Extractor fans are a workhorse in your kitchen or bathroom—but they’re also dust and grease magnets. Over time, they become clogged with oily residue, dust bunnies, and moisture-loving mould. Not only does this reduce their efficiency, but it can also pose a fire hazard or cause unpleasant odours. Fortunately, cleaning an extractor fan doesn't need special tools or professional help. Here’s how to clean extractor fan parts and surfaces effectively with everyday household items.

1. Wipe Down the Outer Grill with Vinegar Solution

Mix equal parts white vinegar and warm water in a spray bottle. Spray the outer grill or vent cover and let it sit for 5 minutes. Then wipe clean using a soft cloth or sponge. Vinegar cuts through light grease and disinfects without chemicals. This method is ideal for bathroom extractor fans or cooker hoods with dust build-up.

2. Remove the Filter and Soak in Hot Soapy Water

For kitchen extractor fans, remove the metal or carbon filter. Fill your sink with hot water, a squirt of washing-up liquid, and a tablespoon of baking soda. Let the filter soak for 15–30 minutes. Use a soft brush or sponge to scrub away grease. Rinse well and let it air dry before reinstalling.

3. Dust Fan Blades Using a Paintbrush or Vacuum Hose

Once the outer cover is off (if applicable), use a soft paintbrush or vacuum brush attachment to dust the blades and motor area. Be gentle—most fan blades are delicate. This step improves airflow and prevents overheating.

4. Use Baking Soda Paste on Sticky Grease

To clean sticky grime, mix 2 tablespoons of baking soda with a few drops of water into a thick paste. Apply to greasy areas of the fan hood or interior and let sit for 10 minutes. Scrub with a soft sponge and wipe clean. Baking soda is mildly abrasive and safe for stainless steel and plastic parts.

5. Clean the Fan Cover with a Microfibre Cloth

If your fan has a removable cover, soak it in soapy water and scrub with a toothbrush. For fixed covers, simply spray with a vinegar solution and wipe with a microfibre cloth. This reduces static dust and prevents dust from returning quickly.

6. Deodorise with Lemon Steam (Optional)

Boil a pan of water with sliced lemons underneath the extractor fan while it’s running. The steam helps release trapped grease inside the fan vents and leaves your kitchen smelling fresh. This won’t replace manual cleaning but is a great maintenance hack in between deep cleans.

It’s not recommended. Bleach is harsh and can corrode parts. Stick to vinegar or gentle degreasers.
