added,
taken away, a change to the manufacturing process?
And is it possible to add some mystic Kickapoo Joy Juice

restore the protective action?
Kodak claimed that they had changed nothing in either the
formula or method of making the stuff. The speculation is
that there was some impurity in one of the ingredients that
caused incidental sulfiding during toning. The sulfiding
probably filled in where the KRST wasn't working. However,
there is no hard proof of this idea.
