T-Max developer - shelf life

[modafoto]

Hi

I have some T-Max developer concentrate (1/5 of a bottle) that has turned pale yellow. Is it still ok for use or should I trash it?
It's about a year old, and has been stored in darkness in the original bottle.

I used some recently that was over 10 years old and it worked but I don't use it enough to decide whether it was still up to full strenth. I'm not overly fond of T-Max

Good Morning, Morten,

T-Max developer concentrate seems to have a long life span. I'm careful to displace the oxygen in the bottle after pouring out enough for my immediate use, but I've used some that must have been around a year old. I've never noticed, however, any with a change of color.

I try to develop some rolls in it if I have some that are nopt that important. But I still have to head out and get some new stuff for the serious work
