Recently found a box of 1/2 dozen Freestyle powdered developer packets - foil/plastic packets to make 1 gal. of Arista 76 and Aristadol (D76 and Dektol).
Near as I can remember these must be approaching 15 years old, stored at room temperature in a centrally heated and cooled house.
Question is is it worth the effort to mix them up and test them or should I just chunk them and buy new?
