I have a 13' 328i xDrive M Sport and the steering wheel is Nappa Leather. I have already cleaned my wheel with Lexol, and the results were just 'okay'. I later read on the bottle that Lexol is not good for soft leather. So what do I use? I have read so many different things... Does anyone here have a nappa leather wheel, and what is good to clean it with so that I get that nice MATTE finish? Cheers!
