I have used "Carbona Stain Devil' remover... you can get it from Joanns. They have 7 differnt ones for diferent purposes. I have used the ink remover.... hubby left a pen in his pocket and it washed and dried. Left a mess in the dryerand all over the clothes. I used it and all came out of the clothing. It is a great product.
I would test it in a small area, but i think that stuff is great!
good luck
