Hi! If you have access to a JoAnn's Craft store - one product that I've had great success with is called StāzOn (All Purpose Cleaner). It's sold in the rubber stamp isle, in with the (rubber stamp) ink pads. But, make sure you get this exact brand.!
Good Luck!!

P.S. Be sure to test it on a scrap piece of fabric first, just in case.
