Anyone else's front hub caps get a nice dirty residue all over them? My hunch is this has something to do with the brakes up there, because the back wheels are always pretty clean...
Oh yeah, happens to mine too. At first, I thought maybe the brake pads were new so they were giving more residue than usual but that doesn't seem to be the case. The other day I washed my BS and had to spend a good 45 minutes just cleaning the front hub caps while the back ones were fairly clean. I'd recommend using "Chemical guys sticky gel citrus wheels cleaner" if you want to wash it off yourself.
