[ARC5] roller incuctior cleaning

[Dennis Monticelli]

I disassembly my rollerductor and gave it a thorough de-tarnishing with a
silver cleaning cream (may have been TarnX).  Then I rinsed and brushed and
rinsed the heck out of it and let it dry.  I then coated the wires with
ProGold from Caig Labs.  It is a preservative for precious metal coated
base metals and has some minor lubricating properties as well.  It has been
10 years and the coil is still shiny like the day I cleaned it.
