Hey Greg...for cleaning purposes, stick with a soft cloth and a mild soap. any type of "solvent based" fluid will eventually dry out the finish and create a dull sheen, or worse, remove the coating..
its really not the dielectric quality( i consider dielectric factor more apt to capacitor usage) of the coating you need but more the insulative factor, protective layer, and visual "prettyness"... if metallic particles are infused in the coating, it may increase the potental of secondary arcing...

What's the safest way to clean a secondary coil coated with oil based polyurethane? I have paint thinner and also denatured alcohol on-hand. Should I buy turpentine or mineral spirits? I don't want to ruin the glossy finish. I just want to clean off dust, dirt, and fingerprints. I've also recently read that polyurethane oil finishes may contain metallic drying agents, including zinc. Metals in the varnish? Seriously? Why doesn't this ruin the dielectric qualities of the cured poly?
