Ever take apart da 606 some off my buttons are not working was wondering if there was a way to clean the sensors and what not

I need to clean mine also, the jog wheel jumps around on me, sometimes I dont even touch the thing and it changes patterns and shit. I am almost due for a new sampler soon

Last month I was trying to take it apart. I wanted to paint it in metallic green. It was alot of screws to undo but I did it. I was expecting to see tons of dust because I had mine since 2005, but it was clean as a whistle, I mean looking brand new. There was a little dust around the pads but the rubber is protecting the sensors, so a quick wipe of a damp rag was all that was needed. Seeing how mint it is, I changed my mind to paint it and kept it in its original state.
