Does nail polish remove pen ink?

Nail polish remover, which contains the chemical acetone, can remove pen ink from some surfaces. Acetone is a strong solvent that can break down the ink molecules, making it possible to wipe them away. However, not all pen inks are created equal, and some may be resistant to acetone. Additionally, acetone can damage certain surfaces, such as plastics or fabrics, so it is important to test a small area before using nail polish remover on a large surface.
