    The Tween series is used by some companies as their wetting agent and is perfectly satisfactory in pure form as used by these companies.

    I've noted that the Photographers Formulary has a proprietary product that is called Formaflo. I've tried that with good results as well.

    Richard;

    At one time, the cap of the Photo Flo bottle was its "measuring spoon" and the instructions called for one capful in a quart (or gallon, I forget) of water. This was so long ago. My goodness, I used to use it with the TriChemPak and with Versatol. So there!

    I'm sure the Photoflow cap is more precise than using measuring spoon!

    Ron,
    You are reminding me of how old (chronologically anyway) I am.

    I am reminded of the story that 'in theory' bumblebees can't fly. A practical test of dish-washing liquids over many years shows that they don't leave 'sticky/greasy' residues. It would be odd if they did when you consider their stated purpose.

    Fanshaw;

    You rinse your hands and dishes after the use of dish washing or hand washing soaps, right? But, after a Photo Flo treatment you do not rinse. This is a significant difference. The "soap" is left in the film but is rinsed off your hands after use.

    Also, any change in Photo Flo formulation over time takes film into its primary consideration. Dish and hand washing fluid redesign does not!

    Wipe Negs too??...after Photo Flo

    At the hesitation of many saying I'll scratch my negs...Does anyone else very gently, carefully squeegee their negs to get rid of excess water (and any inherent salts pollutants, in that water)??

    I use a very soft small wiper blade, carefully inspected, and kept clean. It cuts drying time therefore reducing dust contamination, and the negs are nice and spot free. By the way my last rinse before squeegeeing is photo flo.

    Sirius and Photoengineer, do you have a take on this matter??

    If it works for you, it works. I think squeegees are great if the film does not scratch. You are obviously being careful with dirt and grit. A good squeegee does reduce the amount of water-born stuff which could stay on your negatives. I sometimes use soft emulsions, so am more concerned about scratches. Also, I live in a region with great water. It is pure and soft, so a drop or two of Photoflo does a great job of sliding the water off gracefully. If I had hard water here, I'd have a different perspective on rinsing.

    I dip my Jobo rubber squeegee in photo flow, give it a good shake, and gently wipe the film that just came out of the photo flow. Never ever a scratch, however, I only used Kodak or Ilford roll or 35mm film. Other brands that are softer, I would try it on a test roll, they may be more fragile.

    Non-ionic and anionic are different. Anionic implies something that might react with silver. Although a problem in this case seems unlikely, it is best to stick with things that are known to be photographically safe.
