Remove the trap. Firstly, make sure you have a trap. The trap actually stops odors from coming back up the sink into the room by trapping a small amount of water thus blocking gases from coming up through the pipe. IF you DO have a trap, you should disconnect it and make sure it doesn't have some harsh - gross - items trapped in it thus causing the odor.
