To get ink stains off a vintage baby doll, pull back the doll's hair and remove clothing to keep them from getting bleached. Liberally apply 10% benzoyl peroxide acne treatment cream to any areas with ink. Be careful to avoid the eyebrows. Lay the doll in the sun. It will take more than one application to completely remove all ink. Just keep reapplying until the ink is completely gone.

I fixed dolls for the Council of Xmas Cheer for years. There were always dolls on whose faces some child had put permanent marker. I found that if they were just put in the sun for a few weeks the marks all faded out
Here is some feedback that was emailed in.
The doll has ink on her hand and wrist from a ball point pen, I applied 10% benzoyl peroxide cover up cream to any areas with ink. Placed under a reading lamp and left it for 2+ hours, 98% came off with just wiping the cream off. I applied it again to the small area left on thumb and left it under the reading lamp for another 2 hours, wiped it off and totally gone. This worked really well with little rubbing and no damage to the doll. Tks so much for your comments.
