Moisten a scrubbing side of a sponge with rubbing alcohol or nail polish remover & scrub directly on the nail polish. Moisten with more if needed. Avoid the painted area & scrub in small circles., keep scrubbing, it may take a few minutes.
Wipe the area when dine with a damp rag to remove the residue.
Best to you.
You could try your nail polish remover but it will probably remove some of the finish on your paint unless it is latex flat.
Hi Linda! Nail polish nightmare right! It is amazing how that stuff can stick onto a surface. I believe these links will help in addition to above! Good luck and Happy Holidays to you!
