Another technique to removing the nail polish stain while it is wet is to take a cotton swab or ball and gently blot the stain until all or most of it is removed. This will prevent you from smearing the stain. If you have a larger stain, use damp paper towels or a rag to dab the stain, but be careful not to smear the stain or to drip water onto your leather that will cause the stain to run.
