Plain water. I can't remember if I did a pre-soak though. I always presoak
Efke now. I did get good results using the ancient Windisch compensating
formula. That's the one with just catechol, sodium sulfite, and sodium
hydroxide. It seemed to toughen the efke a little, really handy, since that
emulsion is so fragile when wet. Now I'm just using Rodinal 1:50 or 1:100
for the Efke, and I don't have to worry about Techpan any more.
