I think they use the same formula they perfected with nickel based anti-seize, and just used silver instead of nickle.
SOP when you get nickle anti-seize on your clothes: Stop immediately. Wipe hands on stained clothing. Remove stained item of clothing - yes, right there. Use clean patches of garment to clean up other deposits on hands, face, workbench.
Immediately repeat all those steps until you are naked, because the process for the first piece of clothing will contaminate the second, etc. Walk naked to the garbage cans, throw clothes away, clean your whole body with Gojo (abrasive, because you deserve it), shower, then post on Arfcom about how the shit is STILL everywhere.
