<p>[QUOTE="wlwhittier, post: 4528490, member: 76316"]Here's what y'do: put the rosary in a 2 cup pyrex measuring cup. Add ordinary vinegar to <u>just</u> cover, then fill with hot tap water. Leave it for an hour, take a look; most of that brown rust will be gone, but if not, give it a little more time. Dump the acid solution and flush-rinse 2 or 3 times with hot water, then when the cup is empty, add a tablespoon of Arm & Hammer or any other brand of baking soda (sodium bicarbonate). Leave it for a few hours, giving it time to thoroughly get into the holes in the beads. That step is to neutralize any remaining acid on the steel chain, especially the inaccessible links within those beads. When this neutralizing step has done its work, another 2 or 3 flush-rinses, then a thorough drying to include 15 minutes in a toaster oven or such at ~150F. When they cool completely, work some light machine oil (3-in-1 or equivalent) into the steel with an old toothbrush to prevent recurrence of the oxidation. Wipe 'em down with an old terrycloth tool or washcloth to remove excess oil.</p><p><br /></p><p>This process <i>may</i> have some effect on the damaged discs...but I saw very few of those.
