I've got a few projects underway and one of them is to clean up several old black wrought iron candelabra. A couple of them are totally smooth but two are quite rough. I figured I'd clean them well, and maybe have to sand a couple down if that works (haven't tried it yet) and re-paint them white. Has anyone here done this before by some strange chance? Am trying to do it as cheaply as possible. I probably should apply a rust inhibitor but not sure I'll bother because of the cost of that product.

Any tips very welcome!
