Despite my best efforts to keep my doll clean, her clothing left a stain on her arm, hips, and part of her back. I have seen the expensive little white pots of stain remover. Is there another way to remove stains from the dolls without the expensive creams? I have seen a video where an odorless paint thinner is used to remove permanent marker. Is this legitimate or are all of the paint thinners and removers too dangerous to use on TPE?
