I do not claim invention of cush trick, unfirtunately I can't even remember who taught me that, but it has been a great trick when buying ebay crap-cameras for the last 10+ years
As I can remember, the "eraser" trick goes back to the early 1980's with the IBM PC. It was used to clean the contacts of the expansion boards.

I first learned the eraser trick when I got my Ricoh Singlex TLS way back when (1970?). It was the usual practice back-in-the-day to give both sides of a new battery a light scouring.
