Use a proper wetting agent - NEVER use anything else.
Dilute according to manufacturers instructions and give film final rinse in it.
NEVER use a squeegee - they harbour crap and give you scratches.
Hang the film up. Wet you first two fingers with the diluted wetting agent, gently grip the film between the two fingers and run them down the film. Your fingers are sensitive and you will feel any grit - if you do, stop and rinse your fingers again and repeat.
Wetting agent disperses the water over the film, using your fingers gets rid of the excess.
Drying marks are caused by blobs of water left on the film and the salts evaporate out. If they are on the shiny side they can be polished off with a lens tissue - but it is best not to have them.
Blobs of water on the emulsion side cause distortions in the emulsion through uneven drying. If you see any the best thing is to use your tongue to lick them off (it does work).
Some people actually use distilled water for the last rinse (with wetting agent).
It is important to dry films in a warm, dry atmosphere to minimise drying times. But too much heat will damage the film. In a shower cubicle is one of the best places - if you don't have a drying cabinet.
Hope this helps.
