I am very particular with my gear, and it is probably in the same state as when I bought it, other than the optical surfaces it gets cleaned down after each session, even if it is 3.00am in the morning, and then covered with a sheet inside the observatory.
Then i switch on the exhust fan, and normal air circulating fan and close up.
In the morning I go back and air blow all optical surfaces and, and put the dust covers on, the fans stay on 24/7 until the next session.
But that is just me.

probably over kill but i like it like that.
