Last time I fueled up I had my money up in the sun visor. When I reached up to pull the visor down I got a spot of disels oil on my headliner. Wasn't that big (about the size of a nickel) but it ticked me off. I was wondering how I was going to get rid of it without making it worse or leaving a faded spot when my sister in law handed me a "Mr. Clean Magic Eraser". I broke off a corner, wet it and started rubbing. It quickly took off the grease spot and I can't see any fading in the headliner. Seems to be a great product, in my opinion.
