The Touareg's black leather had 18 months of Wisconsin commuting on it when we ran the Chemical Guys cleaner across the full interior. Seats, door panels, center console armrest. One pass with a damp applicator pad lifted the grime cleanly. The stitching stayed clean. Then we tested a small patch on a borrowed light tan seat. Twenty-four hours later it was noticeably darker. That information is in the cons. Buy accordingly.
