i just use double the car soap, and half the water (compared to washing the car) in a bucket, and that works good on wheels... especially on chrome.. but if its really dirty then id recommend a2z wheel cleaner... non acidic, and safe even on tires... if there are water spots on the chrome then use a polish, such as mothers, or if u wanna use the best there is, then try the 1z chrome polish... they really make a huge difference... look in my gallery (page 2) @ the escalade wheels... i used mothers on them...
