Lacquer thinner would work, but you have to be really careful, otherwise you'll end up taking off more paint than you want to. How I've done this sort of thing is let the paint dry real good and then sand the paint off the tops with a sanding block. Of course the tips will no longer be polished. You might try combining the two and use a lacquer thinner dampened rag wrapped around a block of wood.
