I’m trying to remove them, but some of the color won’t come off. Is such extensive damage even repairable? When buying nail polish remover, make sure it’s real acetone, not an eco-friendly alternative, as these may remove nail polish but won’t clean and remove silicone oil. Use acetone, but remember it’s a solvent; while not a strong solvent, you still need to be careful when cleaning inexpensive sex doll areas before using latex products.
