Can anyone give me some tips on cleaning, sanitizing and lubricating a vintage (used} razor? I recently bought a Gillette Aristocrat, the adjustable model. I would like to clean it, but don't want to do anything that could cause damage. I don't know if the gold colored razors need special care, but I would not know how to safely clean the silver colored razors either. Any one who has experience with this would do me a great favor by sharing what they have learned. Thanks a lot guys, Jack
