I used to have world class drying marks until I moved to a softer water area, and bought a squegee for a friend, tried it on 1st film in new location and found my film dried in a flash (almost) and had no marks. ???? much soul searching
So try distilled or de ionised water for a final rinse, and 2x recommended dose of 'photo flow' or equivalent. I foam the water with the film still in the plastic reel, and then clip to shower rail, stainless clip at top normal close peg (pin) at bottom.
If you want it to dry quicker clean the photo style squegee carefully and give single wipe down immediately you hang it up.
Your mileage may vary, I use the soft tap water instead of distilled, kettle goes 18 months before much signs of a residue.
Not had any drying marks...
