Has anyone out there used the Zaino cleaner and conditioner on gray leather? I would like to know if it changed the color, and how it worked. From what I've read it is good stuff. The leather in my "new" 2002 325i has lost a bit of it's smell. Also, the previous owner was a smoker, and if I leave it in the sun with the windows up, the car will have a bit of a smoky smell. I'll try some odor remover also, I suppose. Any suggestions? thanks.
