Do you suggest I dip the core stack in distilled water instead of
isopropyl alcohol?

 NO!  the pressure could beak those fragile wires. 
 
How about if I blew the air from a distance?  There's got to be a happy

Got it.  No blow dryers.
  More often than not the actual core mat is a cleaner
location with
 plastic covers and the like. 
Not in this case.  The G617 daughtercard is mounted over the G616 as a
plastic cover would normally be, with its core side facing the core on the
G616.  Holding the board up to light and peering into the space between
the two boards, I can see quite a few dust clumps.
