Subject: [Leica] Film processing in almost clean water?

Final rinse you mean. Not wash. In photo flo in distilled water.
Before washing you'd have rinsed it in hype clearing agent. You'd probably
have that in distilled water but it may not make a difference.
The hypo clearing agent HCA might get any yellow out of the film base in
case any had seeped in. if the film base had a very slight yellow tint I'd
think it would not make any difference in printing. Or in archival issues.
The softening of the emulsion by the HCA would probably enable any yellow to
be washed out quickly...as it also washes out residual hypo or fixer.
I think in the history of photography a lot of work had to have been done
with well water. And we look at them every day.
