If its leather....
I'm not sure about that particluar leather but it's probably finished leather like almost all auto leather.
So, leather or leatherette... you are still not treating the leather when you use x, y, or z, product on it in most cases.
Finished leather has a clear coat over it which means you want to care for the clear coat most importantly by keeping it clean with non aggressive but frequent cleanings if possible. Anyway, my point was that most products made for interiors will work on both vinyl and finished leather.
So, if it's leather make sure it's finished or not.
So, assuming it's leatherette, pleather, vinyl, finished leather, etc the products buddhadog mentioned will also work. If you use OPC dilute it and take care. Ultima interior shampoo gel is an awesome and gentle cleaner that takes on 90% of all interiors with ease. A little pricey if not caught on bogo.
