Well maybe you've solved your problem by now, but as soon as I read about it, I ran to ask my husband because he is the STAIN MASTER in our household. He says: a dab of Dawn dishwashing liquid, then with a damp cloth, dab, dab, rub, rub. Let it sit for awhile and maybe you'll have to do the same thing all over again. You will definitely have to get it kinda wet. Good luck!
