I have an opened bottle of HC110 concentrate. What is the shelf life of this stuff once opened?
I've used it two years after opening the bottle with no noticeable effect on the film. This was the thick syrupy stuff not the pre-diluted version.
I used some 4 years after opening, works fine. I think the concentrate lasts forever.
That's kind of what I expected. Must be really evil stuff!!

Rodinal has been reported to be still usable after 40 years in an opened bottle. This is real evil, because it turns deep black after several years.
