Extractor Hood Cleaning: Why It Matters More Than You Think

Your extractor hood works hard every day, pulling grease, smoke and cooking odours out of your kitchen. But over time, that grease builds up — and a dirty extractor hood isn't just unsightly. It's a fire hazard, it reduces efficiency, and it can even affect your health.

Why Clean Your Extractor Hood?

Fire Safety

This is the big one. Grease is highly flammable. A thick build-up of grease in your extractor hood and filters means that a flare-up on the hob can quickly spread to the hood itself. According to fire safety guidelines, grease build-up in extraction systems is one of the leading causes of kitchen fires.

Better Air Quality

A clogged extractor can't do its job. Instead of removing smoke, steam and odours, it recirculates them back into your kitchen. This means your kitchen — and the rest of your home — fills with cooking smells and airborne grease.

Improved Efficiency

When filters are blocked with grease, the motor has to work harder to pull air through. This means:

• Less effective extraction
• Higher energy bills
• Shorter motor life

Compliance (for Commercial Kitchens)

If you run a commercial kitchen, regular extractor cleaning is a legal requirement. Insurance companies and environmental health officers require evidence of regular deep cleaning.

How to Clean Your Extractor Hood at Home

1. Clean or Replace the Filters

Metal mesh filters can be removed and soaked in hot soapy water or run through the dishwasher. For heavy grease, use a degreasing solution. Carbon filters (on recirculating hoods) can't be washed — they need replacing every 3–6 months.

2. Wipe the Canopy and Underside

Use a damp cloth with mild detergent to wipe down the visible surfaces. For stainless steel, use a specialist cleaner and wipe in the direction of the grain.

3. Clean the Ducting (if accessible)

If you can access the ducting, wipe the inside with a damp cloth on a flexible handle. This is often the most neglected area.

When to Call a Professional

If your extractor hood hasn't been deep cleaned in over a year, or if the grease build-up is visible and thick, a professional clean will:

• Soak and degrease all filters in a dip tank
• Clean the canopy, underside and all visible surfaces
• Polish stainless steel to restore the shine
• Check and clean bulbs
