Those little fingernail polish bottles can be tricky. Once the tops are off, they just seem prone to getting accidentally knocked over. The best approach to getting fingernail polish off a counter top is speed. The longer the fingernail polish sits on the counter, the more difficult the stain will be to remove. In fact, whenever you have fingernail polish out, you should have your cleaning tools on hand. This way you can tackle any problems right away with little hassle.
Wipe most of the fingernail polish off the counter, using a paper towel moistened with cool water. Turn the paper towel over, or switch to a clean paper towel as soon as what you're using becomes filled with polish. You want to avoid getting nail polish on the counter again. Keep wiping until you can remove no more polish.
Moisten a clean paper towel with fingernail polish remover, and wipe up the residue. If rubbing with the fingernail polish remover doesn't work, try rubbing with pure acetone, which is available at beauty supply stores.
Mix a solution of 1 teaspoon liquid detergent soap and 1 quart of water. Dip a nonabrasive sponge in the solution, and scrub the counter top to clean up the fingernail polish remover or acetone residue.
Rinse the area to remove soap residue, using a moist sponge.
