1Z leather cleaner is by far the best leather cleaner I've used on Porsche seats. Better than leatherique and lexol or multitude of other products from Meguaiars and other over the counter brands.
I applied it to seats that looked absolutely clean yet after one pass with a terry cloth towel I was surprised to see all the film that came off. Once the seats dry they look new again and not shiny like you applied some sort of cheap product.
p21 is probably the safest wheel cleaner with all the bite of a professional cleaner (not for amateurs). Any synthetic wax will do the trick afterwards as well. I like to finish with Finish Kare 425 spray, it leaves a teflon coating to make wipe downs a snap.
