A great method of cleaning edge connectors on circuit boards is to
burnish them with a dollar bill. The linen and cotton texture of the
bill is perfect for this. No cleaning fluid of any kind needed. 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.


Maybe the app store guy's granddad was in the Navy. If I see him again,
I'll ask.
