Remove extractor fan grease in minutes with 1 kitchen item – not vinegar or baking soda

Grease and grime can build up quickly in kitchens, but one area many people often forget to clean is their extractor fan. Located above the hob, the appliance is often overlooked, yet it collects layers of sticky residue every time you cook. Extractor fans are designed to trap smoke, steam, and airborne food particles through a mesh filter built into the cooker hood. 

But when these filters get clogged, it makes the fan less effective, and can even create unpleasant smells over time. Experts say this greasy buildup can become a breeding ground for bacteria if left untreated. Thankfully, getting rid of it doesn’t have to be a time-consuming job, and you don’t need to rely on harsh chemicals, vinegar, or baking soda.

Cleaning expert Keith Ford, from Crystal Oven Cleaning, recommends reaching for a common household item that many already have in their kitchen: washing-up liquid. 

The humble product is specially designed to cut through grease and works wonders on extractor fan filters.

He explained that soaking the filter in hot, soapy water for around 15 minutes helps to loosen stubborn grease and residue. 

“Washing-up liquid breaks down oils and fats,” he said. “Just leave the filter in the water and give it time to work.”

Nick Small, an appliance expert at AO, agrees. He said: “Ensure you are cleaning this around every three months as it could be full of grease and grime, making it not only dirty but less effective.

“Most filters you can put in the dishwasher, so check the manufacturer’s manual to see if they are dishwasher safe. 

“If not, let the filter soak in hot soapy water for at least 10 minutes then scrub with a brush.”

Once the filter is clean and fully dry, it can be placed back into the hood for a fresher, better-working fan. 

And for those who fry food regularly, this simple method could make a big difference to kitchen hygiene. 

To prevent future buildup, some households use splatter guards when frying or wipe down the filter with a paper towel after each use. 

While these habits won’t eliminate all grease, they can help keep things cleaner for longer.

Regular maintenance like this doesn’t just improve airflow, it also keeps the kitchen smelling fresh and prevents long-term damage to your extractor fan.

For those who prefer using natural items to clean the extractor fan, this might help.
