[ARC5] roller incuctior cleaning

[Richard Knoppow]

    I was remiss in not mentioning Pro Gold. At some time I saw a 
mention of using Deoxit Gold after treating with D-5 even on non plated 
contacts. I can't find this on the Caig site, it may have been on the 
Deoxit Gold label. In any case I've tried it and find it works quite well.
