Dang, I didn't think about Flitz. I have a tube by the fridge. Will try that and the steel wool/ WD40. Might have a brass bristle brush in the tool box.....My the jewelling looks really nice. The rust isn't on any blued area. My concern about the blueing was that I couldn't just dunk it in CLR or some other acidic stuff. It is really fine pin-prick type rust, can't see fingerprints, but it is on opposing sides of the bolt so probably is.
