My daughter purchased a 2006 Range Rover sport-supercharged. The wheels on the car are the stock 20" wheels that are somewhat concave where the wheel contacts the rotor hub. The rest of the spokes are flat from that point to where they meet the wheel barrell. Poor description, I know. I'll try to attach a picture.

Here is my dilema; the wheels dust like crazy ( worse than a BMW) and when I try to clean them the heavy disc brake dust comes right off the barrell and flat part of the spokes but on the concave part of the wheel the black brake dust streaks and the only way to get the black off is to take the buffer to them. They clean nicely with the buffer but when you go to wash them the next time the same thing happens. This week I tried to apply a sealant to see if that will work. Any other ideas?

 

Try different brake pads. Some "dust" more than others.

 

Switch to ceramic brake pads. I have Akebono pads on my Discovery and have been very happy- no dust.

After cleaning those wheels, use a good quality paste wax and put 2 coats on. Your wheels will be so slippery that most dust won't stick.
Yes different pads will also help next time you need to replace them, go for a more dustless type.

 

WAX! 100% carnub wax always works for me. Two light coats and just a soft brush and soapy water. Beware, had bad experiences with those "wheel cleaners" staining pinted wheels. Plus they eat the wx off your wheels. Good luck!

 

Meguire's Cleaner wax works for me...
