I don't know how big of a sign you're talking about, but I'll share a little trick I use during pump restorations for the porcelain faceplates. I soak them in water that has Iron Out mixed in it...Iron Out is a cleaning product. It does very well on rust and even gets the rust from the spider cracking that sometimes occurs in the porcelain and is hard to get out w/steel wool or rubbing compound. I also use S.O.S. pads which work well. Good luck!
