Experts answer: a move I recommend: You find a girl with a nail polish bottle (transparent), then unplug the stereo (or headphones) and a computer plug, you can see the plug on threeSection of sheet metal with a nail polish brush into the middle period of metal look, pay attention to good not to brush to brush next to the metal, the circumference should brush, and other dry painted again, then dried. Then plug in the side when it does not ring, and even if not very, very carefully pull the plug also can not tell, when to resume as long as the use of smallKnife scrape nail polish on it
