I just purchased a gold NEW that has quite a bit of tarnish, a little tooth gunk, and some light scratches on the head. I've spent quite a bit of time reading various B&B threads on cleaning and disinfecting vintage razors. Lots of IMHO, but no persuasive concensus that I can find. I guess I'm hoping for the voice of successful experience regarding the more vulnerable gold-finished razors like the late 30's/early 40's NEW. Any experts out there?
