	The real trick is to eliminate the non-conductive film and
lean the rest.  Sand paper tends to take off the good with the bad.  I
suspect you may have done the damage. 

	I suggest using something designed for the job.  You can buy
contact cleaner spray and it should be accompanied by the contact
lube-protection spray.  I get mine from Radio Shack (Tandy some
places).

Try some DeOxit. I think Radio Shack sells it now. Ive heard from a
reliable sourcevitamin E also works but I havent tried it. I would
have to be out of DeOxit first.and in desperate need. I figure it
couldnt hurt though.

Any weak acid should work: Vinegar, Coca-Cola, etc.

Pour some Coca-Cola on there.  Let it sit.  Rinse it off.  Use a short metal 
bristled toothbrush to clean it, and reassemble.  Use some protectorant on 
there, something as common as axle grease or vaseline to keep it from 
happening again.  Take it easy, as you don't want to take off too much 
metal.

Hi,
Use pencil eraser and rub the contacts. Sand papr is too rough.
