I restore vintage Barbies professionally. I have always had great luck with Oxy 10. : ) Twin Pines is something I have never tried simply because Oxy 10 has always worked. I have used it to remove ink as well as black stains from vintage Barbie slide high heels on their hard vinyl legs. This vinyl is much like that of AG dolls. Once you put a small amount on the stain, set the doll in the sun and check it every 30 - 45 min. Wipe it off and reapply until stain is gone.
