You can improve the effectiveness of your windshield wipers by periodically cleaning the wiper blades. This is a guide about cleaning windshield wipers.
When your windshield wipers seem to not be working well, try cleaning them with simple soap and water. Dirt, leaves, and pine needles get stuck there. Also if this doesn't work, try roughing up a little with sand paper. Good as new.
