Well if it looks like one of those in the first photo.You just about have to take it apart and scotchbrite the contacts. They are usually so tarnished there black instead of shiny silver.And there is really no way to get the deoxit on the metal contacts unless you disassemble them.
I recommend you diagnose and repair the channel drop-out before doing anything else!
My experience: things a much more likely to work out better that way, although I suppose a bad cap is a remote possibility.
