Although some people swear by it in a develop-wash-fix-wash-bleach in mercuric chloride-wash-refix-wash-rebleach in the ferricyanide 30-wash-photo-flo regime, it offers no improvement over anything else listed in this formulary. It is poisonous, and permanence of the holograms is questionable
Shelf life: This stock solution lasts practically indefinitely.
