Polishing of the parallel surfaces of an optical crystal is essentially required for smooth transmission of a laser beam. However, a procedure for polishing the $(00{-}1)$ surface of a material on a molecular scale has not been reported so far. In this paper we have proposed the nano-polishing method of organic crystals by scanning the tip of an atomic force microscope with an appropriate load depending on the surface condition. It has been demonstrated that both the (001) and $(00{-}1)$ planes of 4-dimethylamino-$N$-methyl-4-stilbazolium tosylate (DAST) crystal grown by a seed-standing method can be flattened on a molecular scale. Thus, we have successfully obtained molecularly parallel surfaces.
