I recently acquired a secondhand NES Advantage joystick. I am guessing that somebody was eating Cinnabons or something while playing Mario Bros., as both the A and B buttons tend to stick in the depressed position. Can anybody suggest the best way to unsticky them? I was thinking about just opening it up, removing the buttons and cleaning them as well as their openings, and possibly spraying them with a Teflon grease spray bicycle chain lube I have lying around. Is opening up the stick a Bad Idea (i.e., I'll never get it back together again)? Have any Better ideas?
