Need help cleaning up an old gun
OK... Picked up an old remington 30-06 740 this last weekend up in Phoenix. Long story boring, a friend's dad lent another guy this rifle back in 2001 for the deer season up in Wisconsin. The guy then moved 7 times and never found it necessary to return this gun. The gun isn't worth much other than it was the first deer rifle ever owned by my buddy's father that his dad had given to him back in 1962!! So yeah, a LOT of sentimental value and I'm glad it's in my hands so I can return it over Christmas.
Now, after looking at the gun, it's apparent it hasn't been maintained. I have a decent cleaning kit and will use Remi Oil for the inside but is there anything I can do to clean up the tarnish/rust on the outside of the receiver? Thanks much for any help!
