    I haven't thoroughly tested, but I'd expect its shelf life should be similar to that of D-76.

    Bear in mind, you're mixing up stock solution from bulk ingredients, so there is no reason to make more of it than you can use in a reasonable amount of time.

    Probably a bit better than D-76 as the pH is slightly less. Shelf life also depends on the type of plastic bottle.

    Six months easy in glass or plastic with air tight internal membrane.

    I gave up plastic stuff decades ago and most all the issues with dirty negs went away. It cleans. You can see if it is clean.

    Waterfilter and air filter and a clean darkroom will finish the job.
