I have some very old Kodak Selenium Toner. I've had several people tell me that Selenium Toner doesn't go bad but I'm not getting any coloring with this toner. I've tried dilutions as strong as 1:3 at 90 Degrees but no matter how long I leave it in or what paper I use I get no color change. Once out of frustration I flopped a wet print out of the toner on the counter and walked away. The next morning it had a nice golden brown tone to it. The towels I wipe my hands on have toner stains the next day.
So why is it that I don't get any color change until it dries? I thought selenium was supposed to be a wysiwyg?
