I cleaned wipped the outside parts if I didn't fire a shot. If I did fire some shot, I would clean the inside of the barrel and external part at the end of the day. After the end of the season, I would do a complete strip of the gun and have thin layer of oil onto the barrel. I've found out a perfect stuff to keep moisture out of the fun or those silica packages the kind you found in your new shoes will keep moisture away from your gun.
It is seem like dust and moisture seem to be my most concern. I have a few other guns I like but don't shoot it as often but still need attention once in a while (wipe it down with "hoppe's).
good luck and keep those gun shinny!
