Want to learn an old school trick for getting rust off your firearms?
Well, dig in your pocket for an old penny and you’re almost there. 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.
