Windshield wiper and blade assembly should be checked regularly to check whether the blade assembly is damaged, loose or its parts are broken and tattered. The road paint may accumulate along the wiper blades and interfere with the efficiency of the blades; hence the blades should be frequently washed using soft detergent solution. The wiping machine may be used to loosen bolts, nuts and fasteners and these are to be checked and tapped when examined as part of the wiper blades. The wiper blade elements must be replaced with new ones in case they are broken, damaged, distorted, or ceased to clean well. In order to take out the blade, lift the arm assembly off the glass, pivot the wiper blade until it gets to its stop, then slide the blade off the arm. The opposite of removal is installation.
