RJT> This is a *real* important point,  when it comes to contact cleaners.  The
RJT> are basically two kinds out there,  those that leave a residue
("lubricati
RJT> etc.) and those that don't.  I've always tended to favor those that don't.

 I used to be the same way - until I tried Caig
chemicals. They have some excellent products. I
haven't found any others that work as well as
the Caig products.

 They even tell you, and it's true, that the
less of their product you use, the better the
outcome!

 It also depends upon the orientation of the
chips, the "bend" of the legs, and the impacts
that the piece is subjected to.

 By using a fiberglass brush and always
brushing across the width of the legs, not the
length of the legs, I tend to cut small lines
across the legs (somewhat like a file) that
help to bite into the sockets. This works on
some connectors as well.

 Sometimes, I use a very fine sand paper on
larger connectors and get slightly better
results. This has cured a few units that were
"tough dogs" for someone else.
