Stain remover for tpe dolls

Has anyone tried this or something similar, and did it work?

No. I haven’t done anything like that. I imagine since most of the sex doll industry started in Asia, that they would have ways to clean them. If you try it, find a small spot that is a bit more inconspicuous and work on that to see if it actually works. The long term side effects would concern me on any type of cleaning. Depending on how bad the stains are, I’ve seen some minor ones disappear all on their own with time (it’s like they get “absorbed” right into the skin).
