I went with my wife to a local antique shop looking for some DE's. I found just one, and two SE's. Purchased this for $5 and now I want to clean it. I looked on some other threads and they caution when using "gold" plating. The inscription says PAT. JAN 13, 1920, OTHER PATENTS PENDING.
I know it's beat up and scratched up, so I would like to know how I can clean it while maintaining the "gold" plating.
