aseptic sort set up on Aria

Greetings to all!
      The current discussion on how to best handle the Aria nozzles has 
been both interesting and helpful.  What has been everyone's experience in 
using the aseptic sort set up.	Despite having beautiful drop formation and 
side streams, I have found that as soon as I run the ethanol through the 
nozzle, I run into a problem.  The stream stops and I then have to remove 
the nozzle wipe it off	which defeats the  purpose of setting up for the 
sterile sort.  Is anyone else having this problem?  Is there some other 
solution that could be safely used without damaging the surface of the nozzle?
      All replies are appreciated!!!
