Create a mixture of two to three drops mild dish soap and one-half cup warm water. Stir the ingredients until they are well-incorporated. Mild soaps contain no perfumes or dyes.
Dampen a soft cloth with the mixture and gently work it into the nail polish stain. Wipe away the liquid immediately with a separate soft cloth. If the stain persists, move to the next step.
Dampen a cotton swab with acetone nail polish remover. Gently rub the ivory with the acetone until the polish is completely removed. Dampen a separate cloth with plain water and wipe away the remaining polish and polish remover residue.
Wipe down the ivory with a soft cloth.
