I try not to squeeze wet film with anything, especially squeegee or cloth. Use only filtered water for mixing solutions as well as the last wetting agent bath. Tank, solution beakers and thermometers must be kept dust free and air dried facing down after wash. Give it a good rinse using filtered tap water before use.
Tap water straight from the bidet for the 2nd to final washing, but keep the water speed down. I use Ilford wetting agent on the last wash, just dunk some in and leave for a minute. While the negatives are still in the reels, I give it a good shake down like a dog from a bath. Hang to dry with clothes peg on the top and bottom to keep some weight. Found that the less water it has on the hanger, the less long streaks will form. So try to keep as little water as possible after the final wash. Leave to dry overnight in conditions with minimal moving air ( if it's a room, close all doors and window with no fans running ).
