Simple question.

If anyone has had experience of using Kodak D8 or D9 Lith. developer, how long do the stock solutions keep ?

Pointless mixing a load extra just to go down the drain later on.

Thank you in advance.

When I started doing lith, I used D9. As I recall, it lasted a couple of weeks, up to maybe 10 or 12, in a full bottle. But lifetime dropped quite rapidly with more air in the bottle.

I generally mix small batches.
