this is a cashmere sweater and I'm going to demonstrate how to take ink off of Kashmir or any other kind of wool material I have a sharpie and I'm making a sharpie mark on the sweater then apply the amex to the fabric make sure the fabric is dry do not wet at first because water will set sharpie and any kind of ink you then rub it in you can see that the product is soapy and I did put a paper towel underneath so any excess ink will transfer to the paper towel rub it into the material until you see that the ink is more or less gone it will be very very faint at that point and you can just rinse it in some water or you can put these sweaters in the gentle cycle in your machine if you prefer to wash them that way we recommend rinsing any kind of wool in warm or cool water not hot and that is all it takes you can let it just air dry
