Step-by-Step Guide on How to Clean Bathroom Exhaust Fan
- Turn Off the Power
Safety first! Before you begin cleaning, ensure the power to the bathroom exhaust fan is turned off. You can do this by switching off the circuit breaker that controls the fan.
- Remove the Fan Cover
Use a screwdriver to take out the screws holding the fan cover in place. Gently pull down the cover and disconnect any clips or springs. If the cover is highly dusty, place it on a newspaper or an old towel to avoid spreading dust.
- Clean the Fan Cover
Fill a bucket or a bowl with warm water and add a few drops of mild detergent or dish soap. Soak the fan cover in soapy water for a few minutes, then use a soft cloth to wipe away dust and grime. Rinse off with clean water and let it dry.
- Vacuum the Fan Housing
Using the vacuum cleaner with a brush attachment, carefully vacuum the fan housing interior to remove loose dust and debris. Be sure to reach all corners and crevices.
- Wipe Down the Fan Blades and Motor
Dampen a cloth with water (mixed with detergent if needed) and gently wipe down the fan blades and motor. If stubborn dirt remains, use a compressed air can blow it away.
- Reassemble the Fan
Once everything is clean and dry, reassemble the fan by reconnecting the fan cover and securing it with screws. Ensure all clips or springs are correctly attached.
- Turn On the Power
Finally, turn on the circuit breaker and test the fan to ensure it’s running smoothly.
