I always use a good washing following the fixer--5 minutes or so in tap water. Then I stabilize by letting the film reel rest in the bath for 2-4 minutes with only gentle agitation every minute. When I hang the film to dry I always squeege gently with photo sponges, the same as I do for B&W processing. Removing most of the excess stabilizer greatly reduces spotting. I have not had any difficulty with scratches but always use a clean and damp sponge pair. If you just hang the film to dry then chances are good that you will have considerable spotting when it dries.

The final wash can be done in tap water but stabilizer should always be formulated with distilled water.
