How to Clean Your Extractor Fan Properly
So while letting your extractor fan get dirty causes no end of headaches, the solution is breathtakingly simple.
What You’ll Need
- Newspaper or an old sheet
- Stepladder or a stable base (or just a really tall friend?)
- Bucket of soapy water (washing up liquid is fine)
- Wash cloth or rag
- Towel
- Duster*
- Hoover/vacuum
- Screwdriver (if your fan has a cover)
*We’ve seen people recommend a toothbrush or a paintbrush or similar. A duster is better idea since it’ll collect the dust, rather than just knock it out into your bathroom
Recommended:
- Something to keep the filth out of your hair
- If there are signs of mould, then use a facemask
Not Recommended:
- Scouring agents or brush pads will scratch smooth surfaces and add more places for grime to collect
Preparing
- Turn off the power. Please. Just turn it off.
- To turn it off, use either the switch or the circuit breaker
- Lay down your sheet or newspaper in order to catch anything that falls out – which is hopefully just dust
- Cover your mouth and hair or be prepared to breathe in some very unpleasant particles
Removing the Cover
- Unscrew the cover and remove/slide it off
- You might have to reach behind the cover once loose to undo any spring clips
- If just a bit dusty: use a vacuum on both sides
- If mouldy or sticky: Pop the cover into some soapy water of its own and let it soak
Dusting
- You can use a vacuum here, but a duster is likely easier and more effective
- Dust behind the fans inside the vent
- Clean behind the back of the fan blades, if possible
- Sweep the rest of the fan unit with the duster
- Remember that the goal is to remove the dust, not push it out into the rest of the room
Scrubbing
- Double check you turned the power off. Just for me. I worry
- Dip your cloth or rag in the soapy water and get scrubbing in and around the unit
- Wring it out between uses so you’re not just moving the dust around
- You might need to scrub a few times, and you might have to scrub pretty hard
Drying
- It’s important to dry everything properly, so give it a good wipe with a towel
- Dry the cover, too
Replace the Cover
- Once dry and completely clean, put the cover back on
- Make sure everything is secure and the way it was before you started (except way cleaner)!
