Remove as much of the nail polish as possible with the dull edge of a butter knife.
Apply nail polish remover directly to the dry nail polish stain, using an eyedropper. Allow it to set for two to three minutes to soften the polish.
Blot the hardened nail polish lightly with a clean, white cloth. Work from the outside of the stain toward the middle to avoid spreading the stain.
Change to clean spots on the cloth frequently. Apply more nail polish remover and continue blotting the stain until the cloth comes up clean.
Apply dry cleaning fluid to the stain according to label directions.
Blot the cleaned area with a clean cloth saturated in clean lukewarm water.
