hey guys, ive been bugged about my fender's grill cloth , someone tried to paint or draw a spider thing on it and i was wondering if there was anyway i could clean it off?

ive havent tried anything yet because i dont want to mess it up :P so is there anyway to clean it?? or would i have to buy a brand new one????

thanks for the input guys
