Radio Shack's "Control/Contact Cleaner & Lubricant" #64-4315 does a good job at cleaning electrical contacts. Also CRC "QD Electronic Cleaner" #05102. Will also get inside the female harness as well.


Will that remove the surface oxidation? Never used anything like that so I'm curios.

I can see it possibly removing any loose stuff but it would have to chemically react withe the copper oxide if it were to remove the surface layer.
