This is the first car that I've ever owned that I actually enjoy washing, waxing, etc. I've never bothered doing much to the interior of my cars, other than vacuum and wash the windows. However, having become completely sold on the Griot's Garage line of products I'm tempted to try their "Leather Care" cleaner (although my seats don't appear to be dirty). They also suggest first cleaning the leather with their "Interior Cleaner." Would anyone recommend that these products be used, and if so, how extensively? I have a leather headliner, and it would appear that the dashboard is also made of leather (very Italian!). Thanks.
