Hi there! I own a copper Legendary and take it out to clean it every three or four days when I see that the patina on it has just gotten just god awful. I polish up the externals and the floating pin with little to no effort.BUT my only problem with cleaning it is cleaning the contact that makes a connection with the positive end of the battery. I had been using pencils with erasers to reach through the tube and attempt to clean up that contact. I know I can pop that contact out with a ratchet piece but im wondering if theres an easier way to clean it.
