Extractor Fan Cleaning: How to Keep Your Kitchen and Bathroom Fans Running Smoothly

When your extractor fan, a ventilation device that removes moisture, smoke, and odors from kitchens and bathrooms. Also known as exhaust fan, it keeps your home healthy by pulling out humid air and preventing mold. stops working right, it’s rarely because the motor died—it’s usually because it’s clogged with grease, dust, or hair. A dirty extractor fan doesn’t just run louder; it works harder, uses more electricity, and can even become a fire hazard over time. Most people don’t think about it until the fan stops spinning or the bathroom smells like a swamp after a shower.

Kitchen exhaust fans, a type of extractor fan designed to handle grease and cooking fumes. Also known as range hood fan, it’s the most high-maintenance kind because grease builds up fast—especially if you fry or sauté often. A fan in a bathroom? It’s dealing with steam, soap scum, and dead skin cells. Both need regular cleaning, but few homeowners know how often or how to do it safely. You don’t need special tools—just a screwdriver, some vinegar, and a bit of time. Skipping this for years leads to louder operation, poor airflow, and eventually, a full breakdown that costs more to fix than a simple clean.

Some people try to clean their extractor fan with just a damp cloth, but that’s like trying to wash grease off a frying pan with water. You need to take the cover off, soak the grill, and scrub the blades. And if you hear rattling or smell burning when it runs? That’s not normal. It could mean the motor’s overheating from blocked airflow, or the bearings are worn out from dust grinding against them. That’s when a simple cleaning turns into a repair job. The good news? Most extractor fans last 10–15 years if you clean them every 3–6 months. If you wait until it stops working, you’re paying for a replacement instead of a wipe-down.
