BMW 61612349870 Front Windscreen Wiper Blades Set

Common woes concerning windshield wipers streak and sheet, as well as water beads after wiping and blade chatter. When wiper blades become coated with road film or vehicle wash wax, streaking can occur. These can be cleaned off the blades with soapy water. If it doesn't help, then the problem lies elsewhere; at that point, you should replace the wipers. It is a good idea to replace them twice a year, once before the cold period and once after. Moreover, check the tension spring that acts on the wiper to force it against the glass. Also, replace the wiper if spring tension weak. The presence of water drops after wiping is often indicative of either oily deposits or road film or diesel exhaust on the windscreen, which can be cleaned with an alcohol or ammonia solution or a nonabrasive cleanser. Wiper blade chatter occurs due to dirty blades, a dirty windshield, and bent or twisted wiper arms. To fix this, clean the blades and the windshield, adjust the wiper arm so even pressure is placed along the length of the blade and the blade is perpendicular to the windshield at rest. Light oil must also be used to lubricate the wiper linkage on the driver's side under the hood. If problems continue, the blades may be too old or used and should be replaced.
