Mr. Clean Magic Eraser leaves no residue. It even works on leather seats. I had a friend get into my car with a cheap leather coat on. The brown dye actually rubbed off on my Shale seats. I tried everything to remove it. I didn't want to use anything too harsh or abrasive. A gentle swipe with Mr. Clean was all it took. Presto! The seat is as good as new. I LOVE THIS PRODUCT!!!
P.S. Get the heavy duty version. They're a little more expensive, but hold up much better.
