If you're going to remove the wheels, spend an extra 15 minutes per side and replace the brake pads with some that don't dust. Do a search for brake pads in the forum....a bunch of us went this route. Never have to worry about dust again.
I have used Kleen wheels for the past 4 months (my husband got his last year when he bought jazzy wheels for his Navigator), and washing the car is now a total breeze! No more endless brushing of the wheels or waiting for special spray cleaners to soak the brake dust. If you have fancy calipers, they won't show of course, but I like the look (or actually the even blackness) of the Kleen Wheels. And they do NOT cause over-heating/warping of the rotors. The wheels stay nice for a looong time between washings.
