I accidentally put something on my seats on my 06 STI (blue Alacantara) that had some sticky stuff on it from gray duct tape. The sticky gray material from the duct tape is now stuck on the blue part of my seats! I tried using a little rubbing alcohol with no luck. I need something like "Goo Gone" that won't hurt my seats. A friend of mine said sesame oil might help break down the glue, but I'm afraid of trying it. Any help is greatly appreciated.
