I have been using zaino for years ....here is a link to the cleaner and conditioner.. I clean and condition all my cars at least monthly with this stuff because you get that new car smell again
I use Lexol leather cleaner. I used to use Leather Honey for a conditioner, but I just switched to Adams leather conditioner instead. The Adams has SPF65, dries pretty quickly, leaves a nice satin finish, and smells pretty good too. I really like it so far.
Head over to the detailing section of the SVTPerformance forums, they are a good source of information. Better than most other car specific forums for sure.
