Always read and follow the care instructions and any warnings on the garment label. And, follow the General Rules for washable fabric stain removal.
This is a real tough one, and may be permanent. It can penetrate into the fabric and when it dries coats the fibers in a harden "plaster." Unless there are instructions on the product label, you can try specific stain removal products available at the grocery or drug store, such as Carbona's "Stain Devils®" or take the stain to your dry cleaner and tell them to treat it as a paint stain.
