The ultrasonic cleaning didn't do much to improve the appearance. And I tried three different brands (DeOxit, CRC, Nutrol) of contact cleaner scrubbing with a brush. That also didn't do much. The last thing I tried, an eraser, made the slides look pretty much brand new and it doesn't look like the material was worn. One thing that was interesting is that the last set of contacts on each slide were the most discolored before cleaning, maybe cathode and anode? I should trace it to the schematic. I thought about using emery cloth on the pincer contacts, which is the only thing I could think of that would slide between them. Instead, I just sprayed them with contact cleaner.

The result is that the test button now works well. Time will tell if it hold up.
