When washing soda (sodium carbonate - not bicarbonate) dissolves on the Qwicksilver plate, it releases short bursts of hydrogen, effectively an electrolytic action.
These controlled bursts of hydrogen are just strong enough to draw off the soft ions of surface tarnish but far too weak to effect the hard ions of the metal being cleaned.
The process conducted by this electrolytic metal cleaning plate to clean gold, silver, bronze & your precious metals is harmless to humans and to your treasured possessions.
