When I am on the road my front wheels WILL look like that, and there is not much I can do but stop at a car wash and try to get them washed off... who knows, maybe this person was on the road???

I know here in the south.... all the humidity will make that break dust stick like glue, so short of wiping the rims every time you get in the car ...it is next to IMPOSSIBLE to keep the front rims clean. Welcome to South Ya'll!!!
