Want to learn an old-school trick for getting rust off your firearms?

Learn how to remove gun rust with a copper penny and some elbow grease.
Have no fear. Why not fish around in your loose change and pick out an all copper pre-1982 U.S. penny. Grab some oil and sit down for some light rubbing with the softer than steel copper penny. In a jiffy the rust will be history.
