I purchased a 2007 mini cooper S. It cleaned up really well except for the rims. See attached picture. I have scrubbed and scrubbed these and they don't come clean. Any advice. I don't want to dull or scratch them.

If you also have scratches, chips or curb-rash, wheels can be refinished for a reasonable price. I bought a used Audi with curb-rash, and paid 75-bucks a wheel to have them refinished.
Before I did the Dave.0 rainx treatment, for stubborn brake dust, I have had to use the Ferrous Dueller two or three times. For the tough spots that the blue 3M pad wouldn't remove, I use wooden chopsticks and rub with the big end to remove the dust. The wood doesn't scratch my wheels and allows me to apply enough leverage to the baked on spots to get them to look good.
Good feedback. Thank you. I will need to look into that. Perhaps I have them do the rash along with the cleaning.
Thanks everyone. Follow up on my original post. I purchased the Dodo Juice Ferrous Dueller. I had to do four treatments, but it finally all came off. I used the entire bottle by the time I was done. I have attached before, during, and after pictures.
Now you just need to not let them ever get that heinous again. Hopefully, you gave them a couple of coats of RainX to seal them up before putting them into duty.
