Need safe tarnish remover
From many jewelry supply companies, such as Rio Grande and others, you can buy a
3M product, a black paper that is treated with tarnish retardants. *Small pieces
of the stuff placed with the jewelry in those zip lock bags will prevent the
formation of that tarnish. *
Just curious: Is there any knowledge of using oxygen displacement for
long term storage? vacuum, dry ice, nitrogen...
