How can you Remove dried nail varnish from cotton bedding?

To remove dried nail varnish from cotton bedding, first, gently scrape off any excess polish with a blunt knife or spoon. Then, place a clean cloth under the stained area and apply a small amount of acetone-based nail polish remover to a cotton ball or cloth, dabbing it on the stain. Blot the area until the varnish lifts, taking care not to rub it in further. Finally, wash the bedding according to the care instructions to remove any remaining residue.
