I clean my car every 2-3 weeks (sorry dudes, i really have other/better stuff to do than to wash my car every sunday when it is p*ssing rain here ) and it still happens on my wheels
You need to use wheel wax like i do. Dirt and brake dust then sits on the wax not the rim meaning cleaning is soooo easy
How often do you apply it?
Everytime I clean the car. Its some pink Poorboys stuff I think.....
