I wonder what members with this interior package, I have it on my 09 Z4, have found most effective for treating and cleaning the white leather and alcantara. It has held up surprisingly well so far-just passed 17k miles. I've just used warm water and a soft rag, then add some conditioner. It looks clean, but it seems like it could be better. I have another Z with black leather and after conditioning and a light buff, it looks great. For some reason, I can't seem to get the white looking quite as nice. Any suggestions?
Alcantara cleaner Raceglaze Ltd. (Great Britain) makes alcantara cleaner. Detailbest.com (club members) sells it here. Light leather is always a toughie to clean, and you never know what might work, though you will never get back to 100%. Zymol Treat is good for conditioning, and successfully rejuvinates my old 325is steering wheel!
