Yes, it helps remove smells, but your bathroom exhaust fan has a much more important job: It keeps mold out of your bathroom. After each one of those steamy showers, your bathroom fills up with moisture, which can lead to mold and mildew growth on shower curtains and caulk. A quick post-shower flick of the exhaust fan switch will zap moisture from your bathroom. Keep it clean so it can do its job!
If you’re just looking for a quick fix, blow your vent with canned air to remove visible dust. This won’t clean everything, but it’s better than doing nothing.
Note: If your bathroom has an exterior window, you might not have a bathroom exhaust fan. That’s fine, just make sure you open the window after you take a shower. If your bathroom doesn’t have an exhaust fan OR a window, it’s a good idea to contact a professional to assess the risk of mold in your bathroom.
