    None for me either. But I use only 2 or 3 drops of Photo-Flo for 250 ml of water. Just enough to reduce the surface tension of the water. Photo-Flo uses an anti-foaming agent that contains a tallowate component which can leave a greasy residue. A periodic soaking overnight in a 2% solution of sodium carbonate helps clean any reels.

    As I don't use Jobo, I'm not familiar with that advice, Sirius. Would you mind sharing if their advice also applied to other wetting agents, such as Ilfotol or LFN? Many thanks.

    Jobo states that of all wetting agents.

    A minor detail, it helps to read the instructions and follow them.

    I doubt Ilfotol is any different than Photoflo-200. Even the dilution is the same.

    PS. MSDS lists Potassium thiocyanate as 15-20% and Polyoxyethylated Octyl Phenol as 5-10%.
    I've had streaks with PhotoFlo and none of the others. I've always mixed chemistry very carefully, to the directions till I find a reason to do otherwise. My final rinse is now a mix of Sistan and Sprint End Run.

    Me too, with the final Photoflo 200 rinse diluted much more than Kodak recommends with the film on SS reels in a tank.

    May I suggest you just posted a reason not to follow Kodak's directions? I wash medium format film in 500 mL of distilled water. There is no way I would put 2.5 mL of Photoflo in there as Kodak suggests. I wouldn't even put in a milliliter. I use a medicine dropper and just put in a few drops. As everyone else is posting you only need enough to break surface tension. This thread is comical because Photoflo is the last chemical you really should reuse. It costs literally nothing to mix it up new for each session or as I do for each roll of film. Distilled water is a greater expense at ~$0.84 a gallon.
