I'm no expert but as a painter just go really steady on the stripper, and use something easily neutralized. Cotton bud top might be your best bet for applicator. Acetone works wonders, but perhaps try a bit of softening up with some diluted turps on a nice warm day before bringing out the big guns. Electronics are not forgiving to anything with a bit of bite.
