There's an old saying, coined during the black powder days: "The sun must not set on a dirty gun."
Being a hobby gunsmith and a person who used to keep my varmint bore fouled during season and ruining it because it was stored in an apparently moist environment, I try to clean all my centerfire guns the same day they're shot, or the next at the latest.
There probably isn't going to be much corrosion on guns in the arid states, but here in the East, we have damp basements and very humid summers, so guns not cared for can pretty rusty.
All guns are wiped down that day, but .22LR bores aren't cleaned often, except for handguns, which are always cleaned. They don't really need to be, because the wax on all .22LRs will preserve the bore as well or better than most preservatives. (That doesn't apply to .22 WMR or .17 HMR rounds, since they're jacketed.) The biggest problem with .22 LR handguns is that they shoot really dirty, both revolvers and semi-autos, so they can have FTF or FTE issues if not kept pretty clean in the breech or cylinder areas. Buildup on the bolt and barrel faces are reliablity issues. Dirty cylinders cause extraction problems for DA .22LRs, but single-actions poke 'em out regardless.
