Guys I'm really upset. Just got some really nice 3D Maxspider front floor mats for our X and day one...got a stain on them. Picked up something on my shoe that seemed like it was a greasy blob. Just walking down the street from lunch no less...not even in an area where you would think grease would be. Very sad that I got some of that greasy blob on the brand new floor mats. Was hoping to at least have them nice looking for a while before they get something on them. Any thoughts on cleaning them? I've tried a degreaser, Dawn detergent and Goof-Off. This is how they look still. Very sad and upset.
