The kitchen extractor fan, often neglected, requires regular cleaning to prevent the build-up of grease and unpleasant odours.

Extractor fans play a crucial role in eliminating steam, smoke or cooking smells. If you're noticing condensation and strong odours in your kitchen, it might be time to clean your stove hood.

Keith Ford, a cleaning expert from Crystal Oven Cleaning, emphasised that the cooker hood becomes "greasier and grimmer" the longer it goes uncleaned. However, he assured that it's incredibly easy to restore its shine.

He stated: "With the right match of cleaning solution and scrubbing methods, we are here to help you get that gleaming cooker hood filter back. Here's how to make it sparkle again."

All you need are some common household items, likely already present in your kitchen, including washing up liquid, reports the Express.

It may seem odd, but washing up liquid is designed to break down and remove grease as well as other residues that can accumulate in fans.

How to clean an extractor fan

You will need:

  • Washing up liquid

  • Hot water

  • A non-abrasive brush


Carefully remove the grease filters from the hood. They should easily pop out, but if you're unsure, refer to your manufacturer's guide.

Fill the sink with hot soapy water by adding a generous amount of washing-up liquid, then place the filters in the sink.

Allow the filter to soak for at least 15 minutes, but leave it longer if you have any particularly stubborn grease stains.

Once the time has elapsed, delicately scrub the filter and apply more washing-up liquid to tackle any remaining grease or grime.

Keith shared important advice: "Be gentle with your brushing action to avoid damaging the filters. To avoid damaging the filter surface, do not use coarse scouring tools or pads."

After cleaning one side, clean the opposite side of the filter. When all the grease is removed, thoroughly rinse under hot running water.

Gently absorb excess moisture using paper towels, then leave the filter on a countertop to air-dry. Refrain from using heat to quicken the drying process and ensure the filter is fully dry before fitting it back into place.

Reinstall the dry filter in the extractor hood to maintain a cleaner and efficiently ventilated kitchen space.

To minimise future grease accumulation on your cooker hood fans, consider purchasing a splatter guard, especially useful if you regularly fry food, as this cooking method is a key contributor to grease-laden extractor fans.

Taking proactive measures to maintain cleanliness, Keith recommended: "We recommend using a paper towel or clean cloth to wipe down the grease filters each time you use the hob - ensuring the fan and hood are completely cool before you start to clean."
