I have an Stevens single shot .410 and I would guess it to be at least 30 years old. It has ridden behind the seat of a pickup truck for most of its life also has hung on a gun rack in the house. It has not had much TLC it is quite rusty. I am wondering does anyone have any suggestions for cleaning the rust off of the barrell and reciever. The gun is fully functional as I take it on nightly missions for skunks and armadillos in my yard. Would just like to clean it up a bit and give it a little TLC. Thanks for any advice you may have.
