Rosin build up on violin strings can make them sound scratchy. Although applying rosin to the bow is important to create friction when the bow is pulled across the strings, too much rosin on the strings can reduce the strings ability to vibrate. Clean the rosin off your strings regularly to reduce any scratchy sounds.
