Use regular high quality car soap to wash. US cars don't have the brake compounds that German cars use which require stronger chemicals.Looking for a quality cleaner and polisher wax for new wheels they are a painted matte black, I found a nice kit on customwheeloffset.com but I'm located in Canada so that's a deciding factor.
B5 blue srt. Love that colorMeguiars ultimate all wheel cleaner. The Brembos on my SRT were super dusty. I just sprayed it on, waited a minute or so and rinsed them off. No scrubbing.
