Nail polish is a form of lacquer, and a number of chemicals dissolve it, including xylene, toluene and acetone; the latter happens to be the main ingredient in nail polish remover. Acetone removes nail polish from many surfaces, such as your marble sink, but because marble is porous, there can still be some discoloration once you’ve gotten off the bulk of the lacquer-based item. You can remove this discoloration using a gentle bleach made with household cleaning solutions. In order for the bleach to work correctly, it needs time to soak in.
Empty the sink and then allow the marble dry.
Dampen a rag with acetone and dab it on the stain to remove whatever material is on the surface of the marble. Repeat until the rag no more functions the same shade as the nail polish when you dab.
Moisten another rag using acetone and place it on top of the stain. Leave it there for about 5 minutes, then flip the rag over, moisten it with all this arc and wipe out up to the stain as possible.
Add an ounce of 3 percent hydrogen peroxide to a 1/2 cup of water and then stir in a teaspoon of a mild detergent. Soak a rag using the solution, lay the rag onto the stain and then cover it with another moist rag.
Leave the poultice on the stain until the discoloration has woken out. Remove the poultice, rinse the region with clean water and allow it to dry.
