It's not "faux" leather, it's real leather but protected by a surface coating that helps it last and survive the environment. Decades ago you'd see such a shiny plastic surface that made leather look like, well, shiny plastic. Those coatings did not last and started to crack after a few years, eventually disintegrating altogether. The newer ones perform much better. I would be wary though of applying anything to finished leather that might abrade or otherwise damage the protective coating. My detailer uses only water (I've read that many other pros do this as well). The Prestine Clean product I like is extremely mild and formulated for use on leather but is also designed to clean and protect both rubber and plastic so it seems ideal for treating the various surfaces found all over the interior of our trucks.
