Mix a gallon of photo-flo in a SS bucket (don't worry if it is a little too dilute). Remove film from reel. See-saw film thru the photo-flo for a minute. Wipe excess off between clean fingers. Hang in the film drier.
Replace photo-flo every few days when it starts to get cloudy.
We have up to 125 photo students per semester using the same bucket of photo-flo.
