Glad to hear that you were able to get the dealership to replace the wheels. It's not often that they are willing to go the extra mile to do the right thing for the customer!
I haven't personally used the product myself, but I have heard that "Wheel Wax" polish does a good job of repelling brake dust and contaminants. Another alternative may be to apply "Rejex" brand protectant on the new wheels to keep the contaminants from bonding. The only real solution is to wash the wheels frequently or change the brake pads to a less corrosive compound such as ceramic pads.
