hello, Go to home depot and buy ZEP heavy duty citrus degreaser. I just removed some ink from my couches (grandkids). Soak it very good lightly brush it. don't scrub to hard because your will create fuzz fibers, than use your most powerful vacuum that you have. You might have to repeat this a few times but it will do job. Whatever you do don't use clorox, it will dissolve the fiber material. good luck
