A great method of cleaning edge connectors on circuit boards is to

Don't
ask me how I know this because if I told you I'd have to kill you.


This is really intriguing because a Mac store "genius" told me the
same
thing when I asked him how to clean the connectors on Apple's new USB
to
Lightning cable on the end that plugs into the iPhone. The new
connector
is pretty small, maybe 5/16" of an inch across, and pins are tiny.
Now,
I wonder what whoever came up with that idea and you have in common?

It's really nothing new. I used to work on ship board cryptographic
equipment that had to be opened daily. (Ancient Navy). The contacts
would become dirty and/or worn over time. Cleaning them with the
linen/cotton dollar bill was effective and more importantly didn't
scratch or cause any damage to the sensitive contacts. The method
also didn't leave any residue to inhibit the electrical connection.
