[pure-silver] Re: Wash aid

Someone mentioned awhile back that the Agfa website still recommended
using sodium carbonate.  Certainly if one can get sodium sulfite easily
then use it.  My suggestion was for the "wilds" of NC and I figured that
washing sodium would be readily available.  They still rinse their
clothes in the "crik", don't they? :-)

I think that was the recomendation of AGFA many years ago. However, it
has been questioned as well due to the fact that carbonate is not as
effective as sulfite in breaking down the thiosulfate.

Sulfite can be bought in wine or sausage making stores, so I have to
assume that any country store that caters to that (there is a lot of
thos ein the NC country side) will have it.
