How can we treat 825 Sterling silver items – plated with 18K gold – 3 “micron”?
As long as they are “new”/with pure gold, the best and correct tratment is Hagerty JEWEL CLEAN. If they become oxidized when some of the gold might be worn off, you can use Hagerty SILVER CLEAN. It is not recommended for 3 “micron” vermiel/flash plated gold as this paper this gold should not be polished/rubbed.
