rusty remington 597 need advice
left my remington 597 .22 in my dads gun safe for a few years, despite being oiled when it was put away it developed a large spattering of rust over half the barrel. front site post and the pin in the rear site post have rust but i can see it barely starting on the screws holding the rifle in the stock. the inside of the barrel looks clear and shiny except at the lip of the barrel where i can see rust extending in a few centimeters.
Im wondering the best route to remove the rust I have read to soak a few hours using a rust remover and then scrub lightly with bronze wool. however electrolytic derusting seems the overall best way and i do have a battery charger but i am not sure what i should use as a electrode for a gun barrel. Any advice on either methods or others would help I have been looking for a good tutorial but have not found one yet
