I was wondering about the times people are leaving fibre based paper to soak in water after fixing. I use Ilford Rapid Fix then place the prints into a holding bath until I'm finished printing, then transfer all the prints into a large washing tub for a soak. I was hoping to avoid using HCA to lessen costs and the time spent on another process and just rely on a long soak to allow the fix to leech out. Has anyone done any tests to arrive at a recommended min/ max time? I understand that too much time in the wash can damage optical brighteners...so how much is too much?
