Bathroom exhaust fans are designed to remove moisture from the air after showering or bathing, but they also collect a lot of dust as air moves through the fan. If your bathroom exhaust fan is looking dusty or dingy, here’s how to clean it.
- Shut Off Electrical Supply
- Remove Light Fixture (if any)
- Clean the Fan
- Turn Electrical Supply Back On
Shut Off the Electrical Supply
Before beginning any project involving an electrical appliance, make sure the electrical supply to the appliance is shut off. You can turn off the electricity going to your bathroom exhaust fan either at the switch in the bathroom or the circuit breaker.
Remove Any Light Fixture
If your bathroom exhaust fan has a light fixture, you’ll need to remove this before you clean the fan itself.
You should be able to pull the cover that protects the light bulb off without any tools, and then you can remove the light bulb.
If your fan doesn’t have a light, skip this step.
Clean the Bathroom Exhaust Fan
To clean the exhaust fan, you’ll first need to remove the cover over the fan motor (which is usually separate from any light cover). Removing a fan motor’s cover also doesn’t require any tools:
- Gently pull the fan cover down until it’s a few inches from the ceiling.
- There will likely be two wire clips holding the cover to the fan on opposite sides of the fan cover. Feel around for these, and pinch them.
- With the wire clips pinched, pull the fan cover down further. You may have to wiggle it a little, but it ought to be easy to fully remove the cover.
- Once the cover is removed, use a dry rag to wipe dust from the fan cover and all areas in the fan motor that you can reach.
- Then, use a vacuum with a bristle brush attachment to vacuum up any remaining dust. A crevice attachment may be necessary to get at hard-to-reach areas around the motor.
- Replace the cover (and any light). After you’ve vacuumed all the dust, replace the fan cover by pinching the wire clips and reinserting them into the motor’s housing. Put the light and its cover back in place, if your bathroom exhaust fan has a light.
Turn the Electrical Supply Back On
This finishes the job. Cleaning your bathroom exhaust fans regularly will help them work more efficiently longer.
