Might try fresh fixer as well.
I'm embarrassed to admit it, but I've gotten lazy / cheap / forgetful in the
past and overused my fixer until I've seen similar results on the print
edges after KRST toning. Even with washing the print between fixing and
toning. My bad. To emphasize how ugly the result can be, I found that I
could rub off the stain (which was really a precipitate I guess) after the
print dried. You can't wash out the stuff that creeps in from the paper
edges, though. It seems to be water insoluble or it would have washed off.
You also can create sludge in the toning bath if the fixer is old.. But this
effect is more like precipitation than fudge(but what's the difference
really??).
In case it matters, I use TF4 fixer (alkaline process).
I also have used KRST years and years after purchase, and it's never failed
me (when I use fresh fixer :) )

Hi Eric,
Tomorrow and Monday, I'll work on it, try two different papers and some
more Kentemere, bought more fresh KRST, changing trays (to unused ones),
different bamboo tongs... washing is I described, quick rinse, then 5 min in
HC, then 40 minutes, running water

The the only thing that has ever been them is distilled water. I bought
them for that purpose, 4x22 liters, keep them under the counter. I use
distilled to mix all my solution, stop, developer, fix, hypo and what ever
else needs mixing. Don't trust the tap water for that. Use it in for
washing.
The one thing I find strange is that the prints toned this week, where also
stained in the white narrow borders, and unevenly at that. Found it
strange, so I checked which previous cross section of from the last several
years, which were toned in the same manner, and they all had white borders.
Selenium has been stored in the same gallon container for the past 5-6
years. I'm a creature of habit; good thing to have in the darkroom.
I'll see in the next few days. Will keep abreast.
Looking at the problem from the other end, one can ask, what chemical would
cause the selenium solution to turn into an opaque brown quagmire by the
3-4 print?
Cheers,
