Certain parts of the controller mainly the back, around the + and home buttons and where the dpad is have this...sheen to it from the oils in my hands and I can't get it to completely go away. I'm thinking about modding it with metal Analog sticks so I may change the Shell. But if I don't how in the blue hell do I clean this thing? Nothing seems to work. Wipes, Glass cleaner, Lemon pledge. ..and Lemon pledge cleans everything it's kept my Consoles minty fresh.
