I didn't take any before shots of the interior, but it looked like it had seen 100,000 miles of careful neglect. No fries under the seats, but the leather was very brown and all the vinyl surfaces had dirt in the grain. It looked like you'd want to wash your hands after driving it. But not anymore.... Most of the work was done by the 9:1 APC+ and a nylon Oxo scrub brush. It did wonders on the grainy vinyl, and I also used it on the leather because Lexol wasn't cutting it. I used the APC+ on a seat, then quickly wiped it all off and then hit it with warm water and Lexol cleaner to remove any trace of the APC+. It came out fine, and some Lexol conditioner really brought back the softness the leather had been missing. I wouldn't make a habit of using APC+ on leather, but it worked well in this situation.
