Bathroom ventilation fans whisk away odors, but their more important job is to draw moisture out of the room. Moisture leads to mold and mildew, so a well-functioning vent is critical to keeping your bathroom healthy.
Listen to BOB VILA ON CLEANING BATHROOM VENTS or read the text below:
To work well, your vent needs to be clean, but over time it can get downright grimy. After all, the fan inside is sucking up, not just moisture, but also dust, hair, towel lint, and all kinds of particles from the sprays and powders you use in the room.
Start by flipping off the circuit breaker to the bathroom. Next, remove the vent cover (wear eye protection, because you may get a face full of dust when you open up the vent.) Place the cover in a pail of soapy water while you work.
Under the cover, you’ll see the fan blades. If there’s a lot of dust, you can use a vacuum cleaner to take a first pass at it. Then use a rag dampened in soapy water to gently clean the blades, being careful not to touch any wires. If access is a problem, you can always use a toothbrush or a foam paintbrush to reach up into the unit to wipe away the grime.
Finally, wash and dry the cover and put it back in place. Be sure all parts are dry before turning the power back on. You’ll be surprised at how much quieter and more effective your vent becomes once it’s clean.
