I learned to keep a Tupperware (or similar) container full of distilled water. After a batch of negatives is washed in water, I put a capful of isopropyl alcohol and 1 drop of Photo Flo in the water, stir, and rinse the negs before hanging to dry. No water spots, few dust spots as long as I get out of the darkroom and let the film dry. I reuse the same water over and over again, adding new alcohol and Photo Flo each time. The alcohol helps the water evaporate from the film more quickly, and I think also keeps mutant life forms from growing in the Photo-Flo enriched water.
how do get off water water spots off a negative? I re-rinsed the neg in photo-flo solution and then when it dries, I have a few annoying water spots. Is it possible I need to make up another batch of photo-flo? I've had this batch for a while.
I use photo-flo one-shot and follow religiously the manufacturer indications, using distilled water.
I've never had a single problem that way.
Update.. I landed up making up a new batch of photo-flo. Film still drying but looks good. What a pain.
Why do you make up batches of photo-flo?
It is far more prudent to use photo-flo for a day and then dump it.
Photo-flo is incredibly cheap and used, working strength photo-flo is a great environment to grow mould.

Great question.. Thats the way I was taught.. I guess I could entertain the idea of doing it more effciantly. Explain your process? I have a Petersan two reel tank doing 120. How does your reciepe work? Oz, eye dropper water.. ect?
