Want to clean your fader swtich?
 

The way i cleaned mine was i first cleaned it with water. And i got a knife and clean the inner part lining in the rolly part,and with a q tip the back part of the fader switch and i sand off a bit the connecters. I then when to home depot/ace hardware store and got some black spray paint . I covered up the speaker icon part and the white part for the fader switch and spray painted and let it dry then moved the wheel and spray painted again and so on. For the white arrows and the middle part of the white thing. I basicly taped it out that shape and taped it and i went over with it with whiteout! and let it dry and then the next and next. I did this awhile back i figured i would let you guys know!!
