This is what I found about removing the "conformal coating". "If the "varnish" is an acrylic, lacquer thinner will remove it. If it is varnish or polyurethane, it is much harder to remove. Try lacquer thinner. If that doesn't work you may need a harsher chemical like Marine or Aircraft paint remover, which contain methylene chloride (aka dichloromethane).
