Umm...it's not about Dollfie Dream, but about vinyl doll in general so I hope it's ok to ask; my doll got a *small faint black stain on her face. I didn't put anything near her, though she do have black hair so it could be that. Anyway, how can I remove the stain? Thanks in advance and sorry if it's not the right place to ask.
*I can't even capture it in camera
