Hood Hygiene: How to Clean and Degrease Your Kitchen Cooker Hood

Your kitchen cooker hood plays a vital role in maintaining clean air by removing smoke, steam, odours, and airborne grease while you cook. However, over time, grease and grime accumulate on both the external surfaces and internal components of your cooker hood, reducing its efficiency and potentially causing unpleasant odours or even fire hazards.

Regular cleaning is essential to ensure your cooker hood operates smoothly and your kitchen remains fresh and hygienic. In this guide, we’ll walk you through understanding the types of cooker hood filters, how to clean both the filters and the hood itself, plus maintenance tips to keep grease at bay—all using effective, eco-friendly products.

Understanding Grease Accumulation and Its Impact

Cooking releases oils and fats into the air, which are captured by your cooker hood’s filters. Over time, these greasy particles build up on surfaces, causing:

• Reduced airflow and ventilation efficiency.
• Persistent kitchen odours due to rancid grease.
• Increased fire risk as grease is highly flammable.

Regularly maintaining your cooker hood not only prevents grease buildup and unpleasant odours but also ensures energy efficiency, reduces fire risks, and prolongs the lifespan of your appliance. Simple, consistent cleaning habits make a noticeable difference in kitchen hygiene and performance.

By maintaining your cooker hood regularly, you protect your kitchen environment and prolong the life of your appliance.

Types of Cooker Hood Filters and How Often to Clean Them

There are two main types of cooker hood filters:

1. Mesh Filters
   • Usually made from aluminium or stainless steel mesh.
   • Designed to trap grease particles.
   • Can be washed and reused multiple times.
2. Charcoal Filters
   • Used primarily in recirculating cooker hoods without external vents.
   • Designed to absorb odours and impurities.
   • Cannot be washed; must be replaced periodically.

Cleaning Frequency Recommendations

• Mesh Filters: Clean every 1-3 months depending on cooking frequency.
• Charcoal Filters: Replace every 3-6 months or as manufacturer recommends.

Frequent cleaning ensures optimum filter performance and prevents grease buildup inside the hood.

How to Clean Cooker Hood Filters

Cleaning Mesh Filters

1. Remove the filters from your cooker hood carefully.
2. Soak the filters in hot water mixed with a few drops of Bio-D Washing Up Liquid—a plant-based, grease-cutting formula that’s tough on grime but gentle on your hands and the environment.
3. Let them soak for 15-30 minutes to loosen grease.
4. Use a soft brush or sponge to scrub away remaining grease and dirt.
5. Rinse thoroughly under running water.
6. Allow filters to dry completely before reinstalling.

Replacing Charcoal Filters

Since charcoal filters can’t be washed, check your cooker hood manual for replacement instructions. Always buy genuine replacement filters to ensure effective odour removal and air purification.

Degreasing Cooker Hood Exterior and Internal Components

The cooker hood’s external surfaces—such as the canopy, control panel, and vent—can accumulate greasy fingerprints and splashes:

• Wipe these areas regularly with a damp cloth sprayed with Bio-D All Purpose Sanitiser. This naturally derived cleaner cuts through grease without harsh chemicals, leaving surfaces clean and fresh.
• For tougher buildup, apply Bio-D Multi Surface Cleaner directly, let it sit for a few minutes, then wipe clean.

For internal components like fan blades and housing:

• Turn off and unplug the cooker hood before cleaning.
• Use a soft cloth lightly dampened with Bio-D All Purpose Sanitiser to wipe accessible parts, avoiding direct moisture contact with the motor or electrical areas.
• If you notice excessive grease or dirt in hard-to-reach places, consider professional servicing for safety.

Filter Replacement Guidance

Replacing your charcoal filters on schedule is crucial for maintaining good air quality in recirculating hoods. Some hoods also have carbon impregnated panels—check these and replace as advised.

Additionally, if your mesh filters are damaged or excessively worn, it’s best to replace them to ensure optimal grease capture.

Maintenance Schedule for Long-Term Hood Hygiene

• Weekly: Wipe exterior surfaces with Bio-D All Purpose Sanitiser to prevent grease buildup.
• Monthly: Remove and clean mesh filters with Bio-D Washing Up Liquid.
• Every 3-6 Months: Replace charcoal filters as per manufacturer guidelines.
• Annually: Consider professional inspection and deep cleaning of internal components and motor.
