Aha, someone else with the same problem.   Maybe it is a aqueous problem.
You may have moisture getting up inside the component thru the lead egress.
We had this problem years ago.   I am assuming the component is a through
hole leaded device?   We cooled down the components prior to aqueous
cleaning.
 I think it was 10 to 15 min.   Painful but effective.    Try this: run
some product through
the process then dry them out in an oven for a few hours at 85deg C, then
retest.
If they test good it is moisture.    Why hav you not sent parts to the
manufacturer for
a formal F/A?   Do it-put them on the carpet.

Good luck.
