How about using a vacuum instead?

I was looking for something that could be done with the probes in the
fixture.  Our CM uses a soft brush and compressed air to do PM on their
ICT fixtures.  Compressed air just makes the stuff fly everywhere.

Jim:   
Send me some if your pogo pins, I will clean them up and return them to
you using a chemical we developed just for this purpose, cleverly called
"ProbeWash"...

What is the best way to clean the tips of pogo pin probes? Most of the
manufacturers say just replace them, but we are running high volume with
SnPb HASL finished boards. Some test points have filled vias in the
center so we have some crown points. How many cycles are others out
there getting for their ICT probes? We are seeing contact issues after
about 4000 cycles. I am looking for something that can be done daily of
after every lot to stop the yield from dropping off.
