[ARC5] roller incuctior cleaning

[Dennis Monticelli]

ProGold works on solid metal contacts. I've used it on solid silver relay
contacts and the preservation qualities are evident.  Of course it is a
weak de-oxidizer so something else (like Caig DeOxit) must be used prior.
It's greatest value in the industry is in preserving precious metal plating
over base metal.

The stuff is damn expensive but a little goes a very long way.  I am still
using my original tiny bottle.
