Wow, I just got back from downstairs after cleaning my kicks - then I find this!
Great info guys, good stuff
Just cleaned the soles of my AJ9s with just cold water, a brush with soft plastic bristles, and a good strong arm. I used them for the first time over the weekend, so not much dirt to rid off. I'll give the rubber eraser a try next time
I also regularly clean the soles of my FP1s - also using cold water and a brush. For the gold/black, I apply a thin layer of baby oil - for display purposes
As for suede, as Nike said - hand wash it. My mistake was brushing the suede too hard (I have the white red BB4s). I may have faded the color quite a bit. The thing with the BB4s' suede panel is that it retains too much water. What I do is I let it dry outside - one advantage of living in a tropical country is the sun
As for clear soles, my zoom haven's green, so the yellowing isn't too obvious
I think cleaning would have to be a regular after-thing. I guess it helps if you clean your kicks regularly right from the start (damn I sounded like my mom)
