Grease build-up on extractor fans can be removed in just 10 minutes using a common kitchen item, according to cleaning experts. Washing-up liquid, not vinegar, is the recommended solution for restoring efficiency and hygiene.
Why cleaning extractor fans matters
Grease and grime often accumulate on extractor fans, which are essential for eliminating steam and smoke during cooking. If left unattended, they can become a haven for bacteria, grease, and food debris, severely compromising performance.
Nick Small, appliance expert at AO, emphasises the importance of routine cleaning: "Your cooker hood catches all the smoke and steam from preparing your food, but did you know you could open it?" Without adequate maintenance, filters on the underside of the cooker hood can quickly become a source of unwanted filth.
How to clean extractor fan filters
Experts recommend cleaning filters at least once every three months. Nick Small 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."
Many filters are dishwasher-safe, but for those that are not, submerging the filter in hot, soapy water for 10 minutes offers a simple alternative. Keith Ford, a cleaning expert from Crystal Oven Cleaning, agrees on using washing-up liquid, noting it is formulated to cut through grease and stubborn residues. He suggests soaking filters for 15 minutes or longer if needed.
After the filter has dried completely, it can be slotted back into the extractor hood, restoring performance and airflow.
Preventing future grease build-up
To prevent grease accumulation, a splatter guard can be a worthwhile purchase, especially for frequent frying, as fried dishes are a primary cause of greasy extractor fans. For a swift remedy, wiping the grease filters with kitchen roll or a cloth after each hob use can help preserve cleanliness and prevent lasting deterioration.
