I have never been a great fan of wheel cleaners. Most contain strong chemicals (many acids!) which ultimately ruin your mag wheels by pitting them.
The only one that I do use, and sparingly at that, is Sonax Wheel Cleaner. It smells terrible (a bit like grannie's hair perm lotion) but it works well on brake dust. A good indication of how strong a wheel cleaner is, is to read the instructions. If it says something like: "Do not leave on for more than 30 seconds"...avoid like the plague.
Sonax can be left on for 3 minutes or more. I don't however. I do one wheel at a time and rinse well before using conventional shampoo and a brush and sponge.
