How do you get eyeliner out of a Barbie doll's hair?

did you try rubbing alcohol or heating up a cup of water and laundry detergent ? or even seltzer water and pour it on and let it sit overnight and the next morning put laundry detergent on rub in and let sit overnight and by doing both it should be ok. and for all those sterling silver jewelry owners toothpaste works best even for alpaca. professional cleaners wear away the sterling a little at a time.
