Hello. Interesting Thread. A process recently introduced to me by a black powder gunsmith is Glass Bead Blasting (NOT sandblasting). This process has the ability to remove rust without removing the original patina of the metal. I've experienced this first hand. If you go to the Web-Site (link removed by moderator) and look under Services you will see an original Spanish Miquelet lock I own. The before and after photos are amazing, as you'll see. I don't know the effect it would have on Damascus, but it might be worth asking Earl Kathan. He is very knowledgeable in this area. Might save you a lot of time and experamintation? Rick.
