Well, the problem you're having is that you can't have the oil on the
part, and they can't have the oil off the part.  It's a catch-22.

Personally, I'd work harder on the air.  If the current blower leaves a
drop or two on, then use 3 blowers or air jets.

What are the tests you're running that the oil messes up?  Can you use
the solvent and then re-apply oil after the tests?

Will the tests work directly in the air jet so the particular test spot
will be oil free?

Have you considered torching the oil?  :-)
