I would have wiped it clean and tried it out but it's 5 OVC today....

Thanx

No!

Oil is a pretty good insulator. Oil is used as a coolant in transformers.
It is used to conduct heat away from the non-inductive resistor in a 1Ghz Bird
wattmeter/dummy load that I own.

If your transponder is intermittent, then there is about a 0.1% probability
that wiping the antenna will fix it...
