i like the way you think. it all works as long as:
1 - you keep it wet
2 - you use enough(long enough exposure, strong enough, high enough dosage, et al)
and in an emergency, anything will literally work - sterling silver flatware or US silver 90% coins in tap water using AC 110 60 cycle. we are talking about safe long term use. in an emergency, literally any combination of water silver and electricity will do. better than dying.
