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.
