Things You'll Need
Spilling nail polish on your porcelain or fiberglass bathtub is a simple stain to clean, as nail polish solvent does not damage either of these surfaces. Prevent spills by tightening lids as soon as you are finished using them and by keeping nail polish away from curious children who might spill it. If the stain remover doesn't completely get rid of the pink dye, use a stronger solvent, but neutralize it to prevent it from sitting on the surface and damaging the bathtub.
Apply acetone to a white cloth. The white cloth will help you see the color transfer from the bathtub to the cloth.
Rub the cloth over the nail polish stain. Work until the stain is gone or until it no longer transfers from the bathtub.
Blot a small amount of paint thinner directly onto the fiberglass or porcelain surface if the dye from the pink nail polish is still visible. Use as little paint thinner as possible, but work until the stain is gone.
Mix 2 tablespoons of trisodium phosphate with 2 cups of water.
Immediately apply the solution to the bathtub to neutralize the paint thinner and prevent it from damaging the bathtub.
Rinse the area with clear water and let it air-dry.
