Yep. I am most lax regarding my .22 hosts/cans, and even those have the can removed and a bore snake (Otis Ripcord, really) pulled through a couple of times to get the loose crap out of the bore. Before putting the cans back on, the crown and threads are checked and wiped off with a dry cloth.
My centerfire guns are cleaned every time they're shot, to include the muzzle brakes/mounts. Centerfire pistol cans at least have the rear cap removed and the booster assembly cleaned/lubed every range trip.
