If you use nail polish remover, use the non-acetone kind. A bottle of dark green nail polish wasn't closed all the way and leaked all over and dried on the center console of my car. I used the non-acetone remover and wiped gently. It took a while to get it off, but it was worth the extra time not to damage my console! After I was done, you couldn't tell the polish had ever been there, and my console was fine. So if the non-acetone remover worked on the soft plastic of my car console, it should work on the tub! However, depending on the material of the tub (fiberglass/porcelain), the area where the polish was may be stained. For that, I would be at as a much a loss as you!
