Why it matters
A dust-clogged bath fan can't pull moisture out, leading to mold and peeling paint.
How to do it
Turn off power, remove the cover, vacuum the fan and housing, wash the cover, and confirm it vents to the outside, not the attic.
When to do it
There is no season for this one. What matters is the interval, which is exactly the kind of thing that quietly slips when you are tracking it in your head.
HomeAlmanac schedules this one for you, works out the next due date each time you mark it done, and reminds you before it is late.
