I found some cast iron rusting away on a friend's porch. I asked if I could take it, clean it and return it to her and she accepted. It'll make a nice coming home present for her when she gets back from field work in NC. I cleaned a lot of the rust off with steel wool but I think it was mostly unnecessary, because scouring with salt and oil really did the lion's share of the work.
It needs a little more work around the handles which I am only noticing now in the photos, so maybe cooking on it can be a project for TaD.
