Selenium toner and print washing

[rmolson]

The instructions for Kentmere Fine Print call for an hour wash after toning in selenium and hint at a shorter time using a hypo eliminator .Ilford’s use of rapid fixer times seem based on not toning the prints.
I have a Paterson print washer in a small basement darkroom . It uses about 15 to 20 gallons an hour , which for occasional use is not excessive. Using food coloring I get a complete exchange of water every 30 minutes. but how accurate that is, is questionable .Works great to find leaks in a toilet tank. . So I have the Formulary test solution , but is that a good indicator for selenium toned prints? I can’t seem to find any data on how long the stuff lasts either ..

Selenium toner leaves behind sulfur (and selenium) compounds very much like the fixer does. HCT or a similar clearing agent does help shorten the wash time. Generally, follow the same wash instructions that you would following the fixer. I understand, but don't know, that you can use a somewhat abbreviated wash before selenium toning.
