[Boatanchors] Cleaning roller inductor in situ

[Carl]

I wouldnt use DeOxit it or switch cleaner unless you want a conductive path 
between turns.

I used a sharpenable pencil/pen eraser on my Viking I & II.

If the ceramic is coated with grime then use a toothbrush with Windex or 
other ammonia based liquid. Rinse with clean water, dry with towel as much 
as possible and let air or blow dry the rest.
