Even though I don't have Style 5 split-rims like you all have (I'm still riding on 15" basketweaves here), however I do appreciate how much time and effort it takes to clean these rims. I get a lot of brake dust on my front pads, I personally use a Scotch-Brite pad (never use the green bit though!), the angled sections of the sponge/pad works pretty well in the gaps. However, the pad only really lasts for about a couple of wheels, so you do go through them pretty quick.
