you can try NON-ACETONE nail polish remover (apply a bit with a q-tip). sometimes there's ink stains on vernis and that takes it off, and in my experience, does not damage the vernis. i'd still be a bit careful in doing it though. good luck!!
Sorry, is it very visible?

i hope the stain is pencil; try using a heavy duty charcoal eraser from an art store.
