After using many different wheel cleaners I can very confidently say this is the best on the market. NO acid in this so it's completely safe for your wheels. Does a great job cleaning. I drive a Porsche Boxster S and keeping it clean is my first priority.
I suggest cleaning your wheels once a week since the brake dust that gets on your wheels is acidic and will corrode your wheels over time. I was recommended to try this on a Porsche owners site and I think these people have a very good idea on what it takes to keep a car looking nice.
