My grandfather handed me down an 1864 Springfield rifle and what I believe is an officer's sword. They are both corroded and I was wondering how (or even if) I could clean them. I will attach photos of both and from my research, lots of people have suggested Mineral Spitits, Kroil oil or even just Lime Away for the metal and I'm not sure if I should even touch the wood. I'm hoping for someone's help as I have never restored a firearm before, just shot and cleaned. Also, I am not really worried about depreciating the value of the musket by cleaning it, I am just looking to display it so polishing and brushing isn't a big deal. Thanks for the help!
