<< I got a chuckle out of your contact cleaning procedure. I honestly do not 
 know why this works, but the one dollar bill has been used for decades to 
 clean dirty relay contacts in just the manner you detailed. It also works 
 very good. Both your method and the old dollar bill one reflect a similar 
 process, but what? >>

An interesting way to clean video heads is to take a business card,
put head cleaner on it, and hold it against the video drum and then rock the
drum back and forth to remove oxide buildup.  I've found this to work well on
a seriously clogged video head.  Do not move the card vertically or the 
fragile
head can be broken.

The irregular surface of a dollar bill and a business card may help remove
contaminants from switch contacts.  The cotton content may assist the
cleaning process.  I've not tried a Dollar bill for cleaning - first time 
I've heard
this.  The 3M scrubber material definitely will scratch metal and polish it.
It is wonderful for restoring stainless steel surfaces by rubbing with the 
grain.

It will also remove surface rust and help prepare painted surfaces for 
re-painting.
