Hi Dave,(posted 9149 days ago)I use Sistan for more permanent prints but wasn't sure about a post- rinse. I've confirmed from Agfa's website that you do not want to rinse the print after dunking in Sistan. Just squeegee or wipe off the drops.
I would bet that if the stuff were truly bad it would have all sorts of warnings and precautions on the bottle. I don't remember seeing any special warnings other than the general limitation of exposure. FWIW, I use tongs to handle the prints and just rinse off my hands if I touch the stuff.
Cheers,
