I was at the flea market this week, and came across a booth/table where they were selling a cleaning cloth that used coconut oil to polish/clean metal. The lady assured me it was safe for all metal and finishes. I sadly didn't find my first razor until after I passed that booth, so I couldn't double back to verify her claim. Maybe when I visit next week, I will bring a old razor with me in case she's present again. IIRC, they were 1 for 6, 2 for 10, so it can't hurt to buy one for home and one for the back pack I carry with all my flea market tools, like flashlights, screw drivers, lock tools, water, and dating info for razors/Zippo Lighters.
