I was playing with my dolls today, when I looked closely on my YoMi's face and saw that she had gray/grey/black marks on her chin. I think those appeared when I was at Uncanny Dreams and she wasn't as well protected as usual, and I was wondering if there is a way to get those marks off without ruining the faceup?
I have tried just a bit of rubbing with a moist paper towel, but I am afraid to do any more, since I don't know what is safe, if anything.
She is a Hujoo, and thus not vinyl, if that matters.
