Took this off a automotive leather site...in case there is a question about the interior:
"In fact over 90% of all leather upholstery and leather goods are colored with a pigmented “protective” top coat, in Layman’s terms a “Leather Paint”. This includes automotive, furniture, aviation, marine, jackets, shoes, purses, briefcases, wallets, cell phones cases...I think you get the point.
A “painted” leather doesn’t mean that it’s a bad quality leather. That natural characteristics of the leather itself are extremely durable and when being “protected/colored” with a top coating leather dye it becomes over the top durable. With leather being a porous material if left unprotected it will easily scuff, stain, and fade over time. 99% of automotive leather and over 90% of leather furniture are colored with protective leather dyes. All of the automotive companies like BMW, Mercedes, Lexus, Toyota, Jaguar, Ford, GM and all the rest, even Rolls Royce use protected or painted leathers as a standard install for their models."
My summary:
What this means is that anything you put on top of the "leather" is not actually touching the cow hide. The best thing to do is to keep it clean as was touched upon in the above posts and use some type of conditioner or protector to minimize the wear of the top coat. Lexol does a good job in cleaning and then topcoating with their conditioner. I have used a lot of different product over the years and think 303 does an excellent job. What hurts the leather paint is sweat, body oils, food, and dust/dirt. The easiest way to avoid a majority of wear is to treat the seat with a protective non slip coating and then put on a seat armor seat cover or similar. This keeps the seat clean and reduces the abrasion level considerably. I have done this with many high end cars that I have owned and the leather looks like new years later. Of course you need to take the cover off every once in a while and wash it and then re-protect your seat.
This applies to Alcantra interiors as well, and maybe even more so. The microsuede used for the interior is even more susceptible to stains, etc. If you want your Alcantra interior looking good for years to come, you need to treat it to a microsuede protector such as Dr Beasley's microsuede protector or some other microsuede product. After the protectorant is dry you can then put on your seat armor seat cover.
Remember the key is first keeping the seats clean. Even though you can't see dust/dirt does not mean its not there, even on a new car. Use a high quality cleaner like Lexol or similar interior cleaner ( nothing too harsh) and then protect for your leather. Alcantra has a different type of cleaner.
Hope this helps.
Like the ice cream company that puts the names of the cows the milk came from to make the ice cream.
