While I would not use these on the paint or the body of the car, I do have an unconventional recommendation for cleaning the rims -- BABY WIPES!! I tried this as an experiment yesterday and couldn't believe the results for removing brake dust and other black "stuff" from the rims - I've noticed that if you go to an automated car wash the rims remain dirty even if the car is clean, plus the rims require recleaning between carwashes. Again I wouldn't use these on the paint but I can't imagine them damaging the rims if they're gentle enough for a baby's skin. They're about $6 for 100 at the pharmacy or grocery.
