White dust after c41

[BMbikerider]

Just how long do you wash the film after the fixer stage. If you use a rotary processor it is suggested in most developing kits that 3 mins is adequate with 6 changes of water with one change every 30 seconds. I do 8 changes. I do the two extra changes just because I have always done so. This is followed by the final bath on the slow setting of the motor for 1 minute. I always use tap water for the washing stage, never distilled, and I do not get problems.
Perhaps attention to fine detail is getting in the way of practicalities. This is the same for both B&W, colour and when I used E6 reversal, nothing has changed.

Even my drying procedure is simple and uncomplicated. The films are hung in the doorway of my darkroom where they get a gentle flow of air and dry in around an hour.

I changed the water around 6 to 8 times, so I don’t think the issue necessarily lies with the washing step. When I was mixing the fixer, I noticed that it wasn’t as crystal clear as distilled water — there were some suspended particles visible to the naked eye, although they were so small that I couldn’t identify what they were. So I bought Whatman Grade 4 filter paper to run another test.
