Removing rust from a metal picture frame
I went to a great estate sale saturday and purchased an arts & crafts hand hammered picture in a flat wide heavy metal frame. The frame is all rusted. What the best way to remove the rust? I have searched online and many people have said to soak it in vinegar. Does that really work and for how long? Also, once I get the rust off is there something I put on the metal frame to clean it up or polish it? Is it possible to wax it? Thanks!
