I guess I'm not following - dust?  I use three 8X10 developing trays when
processing the sheets.  Water is in the first tray, and that's where the
tubes go when I rotate them.  Following the developing process, I open the
caps, toss the developer, and place the tubes in the second tray, which
contains stop.  I roll the tubes in that tray for half a minute then
remove the sheets and place them in the third tray, which contains my
fix.  Dust doesn't enter into it.

Developer doesn't get to a portion of the film along the backside (all of
the film doesn't lie exactly along the back).  The absolute worst that
this has ever done is to require that I use PermaWash for a minute to
remove some of the stain on TMX films.

The system works great and I've always gotten excellent results with this
system (not recommended for folks using pyro).
