I've got the Zaino cleaner and protectant, but I don't know how often to use?

Normal situations and climates require a twice a year treatment. Warmer and very Sunny climates require a Quarterly treatment. I try to do my leather in the house and car at the same time, Spring cleaning and Fall cleaning times.

 

Depends on the usage and environment like Dajuice said. I usually do two treatments in a row once a month to keep the leather nice and soft.

 

When my ass doesn't sliiiiide across the seat, when the seats are cool, That's when I Zaino! I clean and condition the front seats (especially the drivers) about once every month and a half or so.
