Old-style print washing—Please fill me in
How did Edward Weston wash his prints? From what I read he made many prints in a good session. I know he had a little light bulb under his developer tray to keep it warm, but I am guessing he used a simple tray method involving elbow grease to wash prints.
I am wondering how well it would work to simply shuffle prints continuously through a tray of water, and dump for fresh water after an interval.
Would this work well? At what interval would you dump the tray to add fresh water? How many changes of water might be suggested? If you know of an effective tray washing routine, yours or an oldtimer's, I would enjoy hearing about it.
Among other ways, I believe he washed them in a running stream on his property.
Using the old timers washing methods, might not work so well today. They often used FB papers with hardening slow working fixers. They also had cheap, plentiful water and no concerns over water contamination with chemicals and silver.

Perhaps a better question would be, how does one get archival prints using modern washing methods?

I don't know how to help you but maybe this will
simple =/ needing a bunch of answers from people on an internet photo site
Seems like you want some some kind of extremely educated simple answer
something even more intelligent than an educated guess but not anything so precise as to be called scientific
Just seems if you want "simple" you should keep it simple
When you want proven ask for proven
I don't know whether there can any inbetween
Put some prints in a tray
soak em for an hour with some shuffling
repeat 3-5 times
or just leave overnight
Will that work just as well
I don't really care
will it work well
Seems like it would do fine
Will it work just as well
I don't care
I'll care when it doesn't and I need it to
Then I'll be done with simplification
simple science performed

All this, I am led to believe, is dependent upon several variables--freshness of fixer, type of fixer, etc.

Large floor-standing rotary print washers existed as far back as the the 1920's. Print washing in smaller applications was not much different than today for the last 60 years or so, such as a tray with a tray siphon, or smaller table-top rotary print washers.
I am on well water in southern California and try to use it sparingly. I soak prints in a large tray changing the water every 15 minutes or so. Then a final wash of 5 minutes in running water works well. This is for RC prints. FB prints are treated in hypo clearing agent then the same wash as for RC. This has worked well for years.
Other than the clinging surface fixer all the remaining fixer

Running water washes are a BIG waste of water. Running water
is not at all a necessity. Still water, with print separation works
well. Fred Picker would agree and has said as much. See the
Sticky concerning film washing. Dan
I tend to use my upright washer for diffussion after an initial blast:
I use hypo clear and then wash for ten minutes on fast/moderate flow then do three or four changes of water, removing them on the last while the water is moving. I dont believe that when ilford says that after using hypo clear the print should be very close to its best after 5-10 mins, people wash for an hour plus on full blast when their (Ilford) results and those from Nova appear to show little to no reduction in fixer product in the paper.
I should add that I have done 20x24s in trays with about six changes of water over about half a day with intermittent agitation, then toned them perfectly with no spots, marks or the like. no idea whether archival but they are still on my wall, catching a fair bit of windowlight and look fine. I suspect they will for another 50+ years...
