"One would never soak paper too long because the fiber based papers had a limit to how long you would want to leave them soaked - too long and the emulsion would slough off. Too short or not cycled enough and the fixer wouldn't wash off enough and you would get a print that yellowed from clinging fixer."
Even with Hypo Clearing Agent, which was, and is, simply a must for fiber based papers, an hour long wash in a Zone VI Archival Print Washer was not out of the question. Never had any emulsion slough off ever, but I never left anything soaking overnight.
Hypo was used for fiber based papers - and no, you did not need to wash for an hour. The directions are to rinse the print with water for a minute, then 2-3 minutes in hypo (with agitation), then 10-20 minutes running water wash, depending on if it was single or double weight paper. The directions are on the package of Hypo.
Yeah, the only reason I know about the emulsion slough off is because I did it a few times back when I was in high school...staying up till the wee hours of the morning in my home darkroom printing and then letting the prints stay in the washing too long because I went to bed...or having to make prints in the school darkroom, then run to class and leave my prints in the wash, etc. It's just a side-note for people who may not realize that is something that could happen.
