Beakers, really. Each time I finish processing film, I do my dishes with hand dish washer soap, the same kind used to wash kitchen dishes. Beakers for developer, stop bath, fixer, tank, thermometer, film washer, everything goes. I then hand dry everything with towels. I wonder if just rinsing with water would be sufficient, and wether soap is bad or not. So far, I have not ran into problems.
Is there a standard practice that i ignore ?
