Sistan/Ag-Stab destroyed most of my portfolio

Ifeel for you. Luckely I didn't have the same experience. These problems have been reported with prints where someSistan residue was left on the print. The proper procedure apparently is:
1. soak in Sistan for the recommended ime
2. wipe off all Sistan residue with a rubber squeegee
3.do not was again; just let it dry.
following this procedure, it seems likely that some Sistan residue is left on the print causing damage. I always used a squeegee, sufficiently large to wipe the entire print clean and thereby never had an issue. I once did a test on the effectiveness of Sistan and decided that a brief direct sulphide toning was sufficient and the better option. So, I dropped Sistan from my workflow.

Interested to hear your direct sulphide process Ralph such as type, dilutions, times and colour change if any?

I made my first print in August 2016. I use Adostab for every print. I don't squeege, but hang the prints from a corner to drain and dry. RC and FB. Adostab has a surfactant in the solution, it runs off without droplets remaining.

I never had a problem, all prints are still fine, last I checked.

I have begun using it instead of flow for fixed and washed film.
It gives a tiny bit of toning, and a stabile negative.
Less likely to give marks than flow too.
You want to gently wipe it down with two fingers though.

I’d never consider going back through my binders and stab every roll though.
Not so much for the work, but also because you never know what kind of weird mistakes you made and, what you left for a later fix, and then forgot it, etc.
