The warning lables make it sound to be as deadly as radioactive waste, so perchance, what is the standard for dealing with the negatives after you do the final rinse of distilled water and photo flo?
wipe off? just air dry? And what kind of residue does it leave behind?
Although Photoflo seems to be almost universally recommended as a way to eliminate drying marks/water spots, I had a terrible time with streaks when using it - and I did mix it with distilled water and at the 1:200 dilution recommended by Kodak. The problem could have been a function of my hard water or maybe I needed to use an even higher dilution than 1:200, but I switched to LFN and have never had a mark since - and no need to finger-squeegee. I also find it more convenient to use - just two drops in 32 oz. of distilled water and you're done.
wipe off between two fingers and let it air dry. The residue left behind by Photo Flow is of no consequence unless too much of it was used, in which case rewashing is recommended.
When dealing with streaking from surfactants such as PhotoFlo and LFN one needs to vary from the recommendations to find what is needed to accommodate ones local waters.
After washing the film with continuous flowing water, empty the tank and refill with de-ionised water. Agitate the film in this for about 30 seconds and then hang to dry in ambient temperature foe about 24 hours. No drying marks and no Photoflo required.
Depending on the water LFN or PhotoFlo may not be an option but a requirement. Water is not the same worldwide and there is on one size fits all.
My water is hard.
If i put a few ML in the bottom of a glass and leave it on the counter, come back in day and it looks like i left milk in the bottom. I can actually build up a business card layer on the bottom of my water glass in a few weeks.
What is the "right way" to clean the reels after using photo flo?
I appreciate that, but if the last ingress of liquid by the film is de-ionised water then no drying marks will occur. Try it and report back.

And exactly why should I mess with perfection and add a step that requires more work and regular trips to buy distilled water?
Because you don't have to buy Photoflo.
My local water requires it. Every camera store would tell you that. Did you bother to read post 16?
