How to Clean Inside Extractor Fan Covers
Tools:
- E-Cloth - Soft sponge - Small brush (such as an old toothbrush) - Basin or large bowl - Dish soap
Step 1: Safety First & Remove the Cover
Unplug the extractor fan to ensure no accidental shocks.
If the cover is removable, gently take it off according to your fan’s design.
Step 2: Soak and Loosen Grease
Place the cover in a basin of warm soapy water and let it soak for 15–20 minutes.
This soaking helps break down the built-up grease and grime.
Step 3: Scrub Away the Gunk
Use a soft sponge or brush to scrub inside the cover, giving extra attention to stubborn spots.
Focus on corners and crevices where grease tends to accumulate.
Step 4: Rinse and Dry Thoroughly
Rinse the cover under warm running water until all soap and dirt are washed away.
Dry completely with a clean cloth or let it air dry to prevent moisture buildup.
Step 5: Reinstall with Confidence
Once the cover is completely dry, reattach it securely to the extractor fan.
Plug in the fan and enjoy a cleaner, more efficient appliance.
Safety Precautions for Cleaning Inside Extractor Fan Covers
Always unplug the extractor fan before starting any cleaning to avoid electric shock.
Wear rubber gloves to protect your hands from harsh cleaning agents and sharp edges.
Avoid using abrasive tools (like steel wool) that can damage the cover or fan components.
Ensure the cover is completely dry before reinstalling to prevent electrical hazards and mold growth.
Do not force or bend the cover when removing or reattaching, as this can cause damage or improper fit.
Work in a well-ventilated area to avoid inhaling fumes from cleaning products.
How to Maintain Cleanliness Inside Extractor Fan Covers: Extra Tips
Safety and Preparation
Unplug your extractor fan or switch off the circuit breaker to keep things safe.
Prepare soft cleaning cloths, non-abrasive sponge, and a mild detergent to avoid damaging delicate surfaces.
Title
Regular Dusting Routine
Dust the fan covers once a week with a soft brush or microfiber cloth to prevent buildup.
Use compressed air cautiously to blow away dust from hard-to-reach crevices.
Title
Deep Cleaning the Grime
Mix warm water with a few drops of mild detergent to create an effective cleaning solution.
Soak a cloth in the solution, gently wipe down both sides of the extractor covers, and avoid scrubbing too hard.

Inspection and Maintenance
After cleaning, inspect for any stubborn grease or grime that may require additional treatment.
Schedule a quarterly deep clean and consider replacing filter elements if your model allows for it.
Common Mistakes When Cleaning Inside Extractor Fan Covers
Not Rinsing Thoroughly
Cleaning agents left on the fan cover can cause residue buildup or surface damage over time.
Residue can accumulate more dust and grease, making future cleaning harder.
Always rinse all parts thoroughly with clean water before reassembling the cover.
Improper Drying
Reinstalling covers while they are still wet can lead to mold growth and unpleasant odors.
Moisture can damage electrical components or attract dust and debris more quickly.
Let all parts dry completely, preferably in open air, before putting them back.
Skipping Vent Openings
Focusing only on the cover’s exterior misses dust and grease trapped in the vent openings.
Clogged vents reduce airflow, decreasing the fan’s efficiency and lifespan.
Use a small brush or vacuum to clean between slats and within vent holes for a thorough job.

How Often to Clean Inside Extractor Fan Covers
Recommended Cleaning Frequency
If you use your kitchen heavily with lots of frying or oily cooking, clean your inside extractor fan covers every 3 months. Frequent cooking leads to heavy grease accumulation, which can hinder extraction efficiency and become a fire risk.
For moderate cooking habits, a 4- to 6-month cycle is usually sufficient to maintain performance and ensure that the buildup of grease doesn't compromise air quality or the longevity of the fan system.
If your cooking is light or you rarely produce oily residues, cleaning once every 6 months can work well, but always keep an eye on any visible buildup that might suggest an earlier clean-up is needed.
Why This Frequency Matters
Regular cleaning ensures optimal extraction performance. Grease accumulation can reduce airflow, meaning your extractor won't work as efficiently, leaving your home with lingering odors and airborne particulates.
Frequent maintenance minimizes fire hazards. The buildup of oily residue is not only unsightly but highly flammable, making a routine schedule a smart safety measure.
Staying on schedule helps with long-term maintenance. Keeping up with regular cleaning can extend the lifespan of your extractor fan and prevent costly repairs or system replacement later on.
Our high-performance microfiber products simplify cleaning, making it quick, easy, and effective, so you can enjoy visible results without the fuss. No streaks, just results.
