B.K.
I used this stuff called TUFF STUFF that i picked up at Target. Its a foam cleaner that can be used on fabrics, carpet or even vinyl. My daughter wrote on my couch with a black sharpie marker and i sprayed it on the stain and let it sit for for about 1 min and i took a damp cloth and wiped it off. It tooke a couple of times but its gone now...good luck and let me know how you make out.
