What is the best way to remover eyeliner from a scotch guarded fabric couch?

It is possibly not eyeliner. It came from the bottom of my foot. It has a similar texture to eyeliner, almost like black crayon. I dont know enough about scotch guarding to determine the best way of trying to remove it. I havent tried anything as of yet. Do not want to make is worse. I appreciate anyone's help and input on this.
