With the cost of Kodak Hypo Cleaing Agent becoming a major consideration, here’s a low cost alternative. Basically, Sodium Sulfite alone will work, but this is close to Kodak formula.
Sodium Sulfite, dessicated 100.0 grams
Sodium Bisulfite 15.0 grams
Sodium Citrate 1.0 gram
(EDTA Tetra-Sodium Salt 1.0 gram, or use Calgon 1gram per litre of working solution in hard water areas)
Dilute stock solution 1:4 for use, discard after.
