I would be VERY careful about general solvent cleaning because it may
cause your flux residues to become more chemically active. IMHO, use
labels that do not leave residues, rather than a botch to clean up those
that do.

This adhesive prevents the board from passing due to not making contact.  The current process requires an operator to use IPA and a soft scrub to remove it. This process is time consuming.  My CM has suggested that we ultrasonic the boards using S-10 solvent.
