Has any one used Oxy10 to remove ballpoint ink from a baby doll face?

My daughter colored all over a rubber baby doll that use to be mine as a child. I have tried everything to get it off: hairspray, alcohol, nail polish remover, powder bleach, baking soda and water. I read online that if you take Oxy10 (acne treatment) and but it on the ink and put the doll under a light that it will remove the ink. Wondering if anyone has tried this or if anyone has another suggestion?|||I think Oxy10 might work to remove the color marks and did you try putting the doll in the washing machine as well??
