After cleaning the wheels I blow them dry. Once complete with the wash, I take the car for a spin. It seems that the nooks and crannies in the steel rotors shoot out a brownish watery/rusty/break dust concoction on the inside of the nice clean wheels. Anyone else notice this? Is there a quick solution other than just letting the car sit overnight to dry?

PS - Should I post this same question on every P forum going to get an answer? Just a little pet peeve I've got
