Anti-Tarnish Zip Bags

I just got some of those Anti-Tarnish Zip Lock Bags treated with
Silver-Guard from Rio. I know a few other suppliers carry them too.
My question: Can you store non-silver items in them also? For
example, turquoise beads, gold-filled findings, wood beads, etc? I
would hate to dis-color or otherwise harm non-silver items.

Does anyone know?

Thanks, as always!
