More good .22 barrels (crowns) are worn out with cleaning than shooting. (typically)
I clean the action of fouling every session and run one wet patch of Weapon Shield Clp followed by a dry one down the bore after a brick or so. Bore snakes are handy to clean .22 barrels with. Just make sure the boresnake is clean so your not dragging dirt down the bore.
I only clean the barrel when accuracy falls off and no before I am not lazy but when I clean it, it seem to lose my accuracy I do wipes and buff the external surface to a clean surface but I've seen and seem to agree even with my other large cals to fight the urge to clean after every range session, it has been difficult but by ensuring the outside if clean with old faithful #9 hoppes I can still get the calming effect by to linging odor of that. Then I do my other reloading task.
I clean the action and put a brush down the bore to knock out residue. I don't clean the bore really good until accuracy drops off. Also clean the mags more often than centerfire.
The American Rifleman just had an interesting article about this topic. Gist was that with modern non-corrosive powders and primers, cleaning isn't really needed as much as we've grown up thinking. Keep the gun in a dry place, clean the bore if accuracy declines, keep the action clean, keep the outside free of fingerprints and such, and it should be fine. Some guns prefer bores that are not freshly cleaned. The old "fouling shot" idea holds water, it seems.

I guess I am the anal retentive one here. I clean my guns after every range session. I use plastic coated Parker Hale and Dewey rods, and clean from the breach when possible. I have even drilled my 10/22 receivers so I can clean them from the breach. While I clean them after every session, I try not to over do it.
