When i bought my ///M it was lady owned. There were some stains on the door panel of a browish yellowish type stuff. Seems like it must have been make up ro something like that. Also got a couple of grease stains from working on the car and having ot move it around. Yeah sometimes its hard to be careful with that interior....I wanted to know whats the best way to bring back to original color...whats the best products out there and what do people reccommend
