My understanding was that after developing in Pyro and fixing in PF's TF-4 alkali fixer the film is just washed in water for about 45min. It is also stated that using TF-4 does not require a hypo clearing agent. Can the use of a hypo clearing agent speed up the wash process, and will using this chemical also wash away the Pyro stain? Thanks for your informed comments.
