    In my ancient stash locker I have a wide variety of unopened chemistry, including D-76, Dektol, Selectol, a couple of Edwal developers, various wet and dry fixers and other stuff. Oh, an unopened gallon of Selinium toner. Bunch of other stuff. Is there much use in tring to use these or should they be disposed? Bill Barber

    Just this week I opened a 12 year-old packet of powdered D-76, mixed it up and the results were great. You never know, but if you're unsure you probably shouldn't try any of it on mission critical negatives at first. I can't speak to the paper chemistry, though.

    You should ship them all to me for proper disposal. They won't do you any good, so I will use , er I mean dispose of them properly.

    Rick, I'm overwhelmed by your offer to dispose of my bits. You are too kind, I couldn't impose on you. <{B^)

    Here is a list of most of the stuff. I would be interested if anyone has suggestions on what to keep and what to throw away (dispose of properly.)

    Sodium Thiosulfate 7 or 8 lbs.
    Hyroquinone
    Selectol-soft deveolper
    D-76 several packages
    Kodak Hypo Clearing agent ( a bunch)
    Pyrocatechnol 100+ grams
    Potasium Bromide
    Kodak Croein Scarlet 2 OZ
    28% Acetic Acid Several bottles
    Agfa Neutol WA
    Kodak Rapid Fix with Hardner 35 oz (2 of these)
    ethol LPD paper deveolper 447 grams
    Acufine 2.1 oz can X 2
    Rodinal 4oz
    Sodium Sulfate
    Potassium ferocyanide
    Potassium citrate
    copper sulfate
    Kodalith fine-line developer set (part A & B)
    Farmers reducer

    That has most of it, althought there is some toner and a few other smaller items. The toner looks dead, although unopened.

    I would use old chemistry for paper developing, many use D76 and other film developers as paper developer. It that way no risk for the negative :smile:

    The packaged developers and fix are most likely still good to use. The bulk chems, if you are mixing your own formulae, should be good, otherwise dispose. If you think they are good, but don't use, sell them. Sounds like you have enough stop to last a lifetime.

    Sodium Thiosulfate 7 or 8 lbs. probably still good
    Hyroquinone still good if slightly off white it can be a light gray, tan, or violet color
    Selectol-soft deveolper depends on integrity of packages
    D-76 several packages same as above
    Kodak Hypo Clearing agent ( a bunch) probably still good
    Pyrocatechnol 100+ grams see comment for hydroquinone
    Potasium Bromide still good
    Kodak Croein Scarlet 2 OZ still good
    28% Acetic Acid Several bottles still good
    Agfa Neutol WA if a liquid then it is iffy
    Kodak Rapid Fix with Hardner 35 oz (2 of these) iffy
    ethol LPD paper deveolper 447 grams probably still good if powder. iffy if liquid
    Acufine 2.1 oz can X 2 probably still good
    Rodinal 4oz depends on whether the bottle is unopened or not
    Sodium Sulfate still good (do you mean sulfite?)
    Potassium ferocyanide still good
    Potassium citrate still good
    copper sulfate still good
    Kodalith fine-line developer set (part A & B) iffy
    Farmers reducer probably still good
