10.9.1 Glass cleaners
Wipers are necessary for timely and high-quality cleaning of glass from water and dirt during the rain in order to maintain the possibility of car movement. In case if it's just raining, the wipers do the job themselves. But in case if you are driving on a busy road and your car is covered with mud and water with enviable regularity, the wipers will just spread the dirt, covering the entire windshield in an even layer and concealing the road from your eyes. Then a washer comes to the rescue, which sprays a special liquid through the sprayers. By rinsing the dirt with liquid, the wipers remove it from the windshield.
