Looks like cleaning with a camel's hair brush while the encrusted coins are in a proprietary ph neutral's (7 or so) solution is the "secret."
Sodium salts and a sable hair brush...

reminds me of a botanists lab or greenhouse, so lets call this room: "Garden of Gold!"
nice vid. SS is a popular subject on this forum.
Have seen this before, but worth watching twice.
Quite the process.... An amazing treasure indeed. I lived in the Caribbean for years, and always, when swimming or on the beaches, looked for gold coins.... Never found one... Cheers, RickO
That is very enlightening. Thanks. So the sodium salts is a very very mild acid bath? Peace Roy

Sodium salts is a very broad category,.. can be neutral (pH 7), acidic (pH < 7) or basic (pH > 7)

Funny, that is not quite what I would have said. Salts tend to be basic in their nature or neutral - sodium chloride in water by recall is 7.0.
Well, just Love coins, period.
