Making old nuts, bolts and clips new again

We left the metal in longer than 24 hours because it was bubbling and we wanted to see what it was going to do. It was taken out of the vinegar late this afternoon after we were done working on the Dart for the day. The top was almost totally rust free. The rest of the remaining rust was easily removed with a round soft kitchen scrubby typically used on dishes. The dark areas in the photo are places that the rust either ate or etched. This was very thickly coated with rust.
