I mixed 500ml of stabilizer, developer, bleach and fix from the digibase C41 kit about 3 months ago. I only developed 4 rolls and then they have been untouched and well stored in air tight containers in a cool, dark environment. Now, I'd like to develop another batch of film and I'll probably mix up some more developer to be on the safe side but how can you tell whether the other chemicals are still workable. I know how to 'clear' test the fix, but is it possible to test the stabilizer and bleach?
Thanks for the help.
