Helding water overnight will dissipate the chlorine and won't bleach the
dark values. Citric aicd is the one to use, it help clearing the ferric
salt and won't bleached the image.

So glad to have found this list and the incredible community that thrives
I just started with argyrotypes this week, trying papers, exposures, etc.
Today I used distilled water for the clearing step and it helped maintain
my dark values whereas my ordinary tap water here in So California, seemed
to bleach back the image. I understand that adding citric acid can help
quite a bit in this regard. If I held water overnight in order to let the
chlorine dissipate and added citric acid, would that help with what I'm
experiencing? Could another acid be used, maybe acetic acid or a bit of
distilled white vinegar?
Thanks all...looking forward to participating here and learning from all
