Hello: I recently purchased a new condition Norinco Model 1897 Trench shotgun. When I took it apart to inspect and clean it, I was surprised to find red rust on the inside of the magazine tube, inside the receiver and in the trigger group. The rust was glistening under oil and factory grease. After hearing similar stories, I am convinced the factory didn’t properly remove all the bluing salts. Is there an effective home remedy to completely remove these leftover salts and stop the rust? This is the only gun I own that has this problem.
thank you very much, Jennison
