Ilford recommends a water-saving washing procedure which, if it is adequate, saves a lot of water and allows using water from a bottle at room temperature rather than from the tap. The procedure requires using a non-hardening fixer. After fixing, the tank is filled with water and inverted five times, drained and refilled and inverted 10 times, and finally drained and refilled and inverted 20 times. That's it.(posted 8889 days ago)Ilford says that "this method of washing is faster, uses less water yet still gives negatives of archival permanence." If found an article by Rolf Suessbrich testing this procedure, and pretty much confirming it. Suessbrich stresses reducing water takeover from each of the three washing steps to a minimum by washing the tank, and even drying it.
This method seems great, but I am left wondering about the archival quality of the negatives. Does anyone have experience with this method? Is it enough to wash film this way?
