Note this is longer than the usual 2x for acid fixers. Wash two minutes in running water, and no clearing agent is needed.
For processing in a Minox tank: To 75 ml of water, add 17 drops of Kodak HC-110 stock solution, and 15 drops of Agfa Rodinal concentrate. For standard steel tanks: To 200 ml of water, add 19 drops of HC-10 stock solution, and 17 drops of Rodinal concentrate. Use HC-110 diluted to stock solution, not straight concentrate.
