Boopaints said:one more thing you can try is nail polish remover. Test with a q tip.
Yes, if it's just a laqured coating acetone should remove it, but you may need to soak it for several hours. Failing that dichloromethane (DCM) or tetrahydrofuran (THF) would do the trick, but I'm not sure if you can buy that comercially.Paint stripper would also be worth a try.
