It really did work but The texture of the bills has changed drastically 
in the last few years.

I believe a NEW  $5, $10, or $100 with the $00 being the best.  I don't 
have any $50 bill to compare, but at least with the older ons, a new $50 
actually was quite effective.

The new ones with that finish on them should work.  I don't know reahhy 
whether one of that new issue makes a better contact cleaner than any of 
the others.  I rarely have anything bigger than a $20 <:-))
