Don,
I have always used my stencil cleaner.....course, you'll want to test your
cleaner process settings. The board misprints may take a little longer to
process then the stencils. DO NOT wipe the boards off before cleaning. This
pushes solder balls into vias and into etched areas, and they can be very hard
to remove. Good luck.

We are presently implementing Laser Inspection of our solder paste
operation. We are experiencing a 10% fall out at paste inspection. We
want to be able to clean these printed wiring boards for reprinting
with paste. Is there anyone out there that has any experience with
this cleaning process? What are you doing to clean the boards in
order to still meet the cleanliness requirements for ROSE testing?
Any help you can give me would be appreciated
