À: pure-silver@xxxxxxxxxxxxx You also could just use a water rinse between the acid stop bath and the fixer. Should take care of any care over for all practical purposes. A dip for a few seconds in a tray of pure water should dilute anything left on the print that what made the fixer should be unimportant. The water rinse is what I do between a citric stop bath and a neutral fixer. That prevents the release of sulphur dioxide for which I have some sensitivity. Claudio Bonavolta www.bonavolta.ch
