Welcome to B&B Archangel. I moved your thread to the Safety Razor Forum. You may get more answers there.
For any razor that's not gold, I boil it for 5 minutes, polish it with Flitz metal polish and wash it. I then soak it in alcohol for around 5 minutes followed by a rinse. Finally, I finish with a little Dovo sterol to lubricate it and I'm good. Works like a charm.
I ruined one gold razor doing the process above and haven't tried another.........
