My left joystick's input seems to dropout momentarily, especially when I push it in any direction in the top half of the joystick (i.e. directly up, up-left, up-right, etc.). I already tried taking the controller apart and putting cleaning solution in the joystick (i.e. BW-100), but it only solves the problem temporarily. Is there anything else I can do that doesn't involve replacing the joystick?
