Are you supposed to clean smoke detectors? Mine are 12 years old.
Reason I ask is I have 4 at heights 14-16 feet off the floor (cathedral ceilings) & not easy to get to.
I vaguely recall at the university where I worked they had some maintenance people who went around cleaning them in residence halls & the academic buildings (hundreds of them on campus). I think it was spider webs and accumulated debris the insects brought in they were removing & cleaning out.
Thanks for comments.

additional note of embarrassment:
I ran a feather duster fluff on extension pole around a skylight to get spider webs months ago, about 3 feet away from one of the smoke detectors connected to our alarm system and accidentally set off (dust I guess) the alarm system (which calls fire department automatically). Installed 12 years ago I forgot how to turn the darn thing off immediately (LOUD TOO) many minutes later had to call my local fire department to make certain no false alarm had been called. Explanation no doubt amused some dispatcher for the day.
