Disband the terrorist EPA (A terrific idea regardless) and we could go back to
Freon vapor degreasers.

Fred,
Gary and I both have been using acetone for a long time.
If the board is flooded, the results can be catastrophic since residue flows
under components and makes a mess.
But carefully applied with a swab or small brush to a small area and mopped up
with a paper towel it will do the job very well. The contact time *must* be
short, and that is why one must work in small areas.
Yes, alcohol can do a good job of cleaning flux too, but needs to have the
same precautions - it can make just as much of a mess or more because alcohol
attracts water vapor and causes it to condense on the surface being worked.
Dip an opaque object in alcohol and remove it with a paper towel - note that
the object will be wet with moisture.
Besides, the job for the particular problem stated was not flux removal, but
removal of some unknown compound from connector pins. Alcohol is likely to be
ineffective.
