If you’re referring to the Nutone 744NT (combo vent fan and light) they’re inherently weak, and junk, in my opinion. You can remove the bulb and trim ring to remove the dust, but it’s a waste of time.
The best suggestion is to add a digital timer switch and let it run 20 minutes after you shower, to remove moist air.
