the stones need to be immediately dried after the dip though and
*never* use this with pearls, or any other nacre containing or
porous natural embellishment (like some unsealed/unfinished coral
The process is pretty mild. I’m unsure about the water softeners, so
he caution might still apply (salt is harmless). but if you’re
unsure, use ordinary washing soda (sodium carbonate. Not baking soda,
though even that will slowly work), by itself, with the aluminum. The
chemicals are just there as an electrolyte, it’s the electrical
reaction between the silver and aluminum that causes the cleaning.
Washing soda will not harm any stones or pearls. About the only
thing I’d not use it on would be foil backed, glued in, rhinestones.
This simple solution is a little slower than R. E. Rourkes, but does
the same thing.
