    Hi- I have a bottle of Tmax developer, never opened that is about a year past the expiration date on the bottle. How long have people found it to maintain full activity (past expiration)?

    Thanks,
    Tim

    Good Evening, Tim,

    T-Max Developer concentrate is generally viewed as having a very long life. It seems likely that unopened full bottles will maintain strength longer than partially-used ones will. I know that I have used some fairly old (almost certainly on my shelf for upward of a year and who knows how long sitting on a dealer's shelf) T-Max with no apparent problems. Process one test roll and see what the results are; my guess is that you'll be OK.
