Sodium Sulfite (anhy) 15g
Acetic Acid (28%) 48ml
Sodium Metaborate 15g (or Borax)
Potassium Alum 15g
Water to make 1L
Or, if you don't want to mix it yourself just buy some standard Kodak Fixer (powder) or Kodak Rapid Fix w/hardener. Don't know if Kodak chemistry is readily available, yet (given recent issues), but I believe it will return soon.
