S.L.
Try Goof Off or Goop Off. It is good for fabric and pulled out paint and silly putty from a comforter. It is usually found in the laundry isle, on the top shelf. It is kinda oily at first, but it washes out cleanly. I had to use a white cloth and rub it in for a good 5-10 minutes, but the paint and putty came out as I scrubbed. A trip into the washer and dryer, the comforter was as good as new. And MOM saved the day again . . .
