Darkbulb and I discussed this at length when he got the razors. The process that Darkbulb will use is the electrolytic process with baking soda and aluminum foil as shown in the thread below. http://theshaveden.com/forums/threads/another-gillette-single-ring-cleaning-picture-heavy.25538/ As to the polish, the particular polish Hagerty Silversmith polish IS DESIGNED SPECIFICALLY for use with Gold and Silver and even electroplated items, unlike Flitz or MAAS which are general purpose polishes. which can remove some metal.
