Martin,

I swear by (not at) Kodak's Photo Flo or Agfa's equivalent. I mix it in the
recommended 1:200 ratio, 2 liters at a time, in distilled water, and bathe
the film in it for 30 seconds as the very last step before hanging it to
dry. The instructions say NOT to agitate, and I don't. I have never had
streaks or any kind of drying marks.
