    According to Mr. Rudman's comments and expansion
    of the subject in the thread "Potassium Ferricyanide
    Questions", sodium chloride is entirely usable. From
    reading I'd go for P. Formulary's pure NaCl.

    What have you in mind for that after the bleach
    silver chloride image? A sunbath and ? Dan

    I repeat, it can be done but you can lose highlight detail in prints due to the blixing potential of ferricyanide-chloride. If the concentration is very very low, then it will affect some highlights and bleaching will be incomplete in shadows.

    If you wish to use it, use the purest form of NaCl to prevent stains or discoloration. Do not attempt it with ammonium chloride, as that is an even better silver halide solvent.
