polishing jewelry with sodium bicarb is not wise, it will ABRADE the soft metals and stones.
DEtarnishing jewelry (especially silver) is a good thing,
but this is simply a chemical reaction that converts surface metal back to the UNtarnished state,
it's not a true cleaning unless a brush or u/s gizmo is used.
a water/bicarb solution with a bit of aluminum foil can be used as a DIP.
the tarnished silver will DEtarnish in the solution (and the aluminum foil will darken)
IF an acid wash has been used on the stream a solution of bicarb/water can be used to neutralize the acid.
again it is simply a chemical reaction, no buffy/rubbing is required,
just wipe on rinse off (about 5-6 cups of water PER cup of bicarb)
using sodium bicarb to mechanically polish doesn't make much sense...
what "grit" is the bicarb?
there is an urban myth/internet viral post about some guy selling baking soda/water for polishing at 20$ a bottle in hiway rest stops...
the story includes a magical polishing demo and then the guy DRINKS some of the stuff to show it is 'safe'...
