I’ve recently started stocking my work in a store. And owing to the
hot and very humid weather, the silver turned black in 2 weeks. The
pieces are kept in a partially closed glass counter on a velvet base.
As the store is not very close to my house, it’s not easy to pick up
the pieces every fortnight to polish them. What are my options?
-Mix 1 part with 3 parts hot water, mix well, allow to cool fully,
soak item for minimum of 10 minutes, rince off under luke warm
running water, blow off with air [never wipe], put item[s] aside for
2 days for coating to harden.
Do you use a citric or nitric passivation? Or, is there another kind
that works on sterling silver? Do you know of a product name that is
sold in small quantity (e.i. 1 or 2 liter)?
