Got my very new old I grade hammer gun in on the goose action for the last two days of the gunning season. Enjoyable and successful but I am curious how to go about cleaning it to preserve its condition while still enjoying it fully in the field. I think the gun may have been waxed by its previous owner? how do you clean and oil the metal around the hammers without causing oil damage to the stock?
help and methods appreciated
