I have looked over the photos from the previous posting, and believe the reddish material is a corrosion product rather than simple rust. I would further speculate that it comes from inadequate removal of the highly corrosive soldering flux used when the pins and attachments were soldered in the bracelet. If this is indeed correct, which it might well not be, the material could be removed by lightly polishing the surface. I hope you will let us on the forum know when you get this attended to as to what the cause was.
