Acetone should remove the lacquer - it’s the basis for most “paint
stripping” products. Depending on the thickness of the coating, you
may actually have to soak them for a while to get through the entire
layer. Look for the straight acetone, rather than nail polish remover
that “contains” acetone – you’ll get much better results.
Remember to use good ventilation and proper handling techniques to
guard against spillage.
