Most vehicle models have one long and one short wiper, with the driver's side being longer and the passenger side shorter. This design ensures absolute clarity of the driver's vision, protecting the safety of passengers during rainy weather. Of course, there are also models where the driver and passenger side wipers are of equal length, primarily because these vehicles have windshields with larger curvatures. Using wipers of unequal lengths on such windshields may result in missed spots. It is recommended to replace wipers with the original size specified for the vehicle and not to increase or decrease the size arbitrarily. Methods to extend the lifespan of windshield wipers: 1. Avoid dry wiping; always spray windshield washer fluid before activating the wipers to prevent damage to the rubber blades and motor. Regularly check the level of the washer fluid. Typically, the washer fluid filler cap only indicates the "MAX" maximum level and not the minimum, so drivers should keep an eye on the fluid level and top it up when necessary. 2. If the windshield is very dirty, with sand or dust, clean off the debris before using the wipers. Do not rely solely on the wipers to clean everything, as this not only wears out the wipers but may also scratch the windshield with the dirt. 3. Using specialized wiper fluid or windshield washer fluid can better protect the wipers and improve the cleaning effect on the windshield. During winter, it is essential to choose antifreeze windshield washer fluid. 4. In cold weather, always check if the wiper blades are frozen to the windshield before use. If the wipers are stuck to the windshield due to snow or frost, never rinse them with hot water directly, as the sudden temperature change can cause the windshield to crack or the wipers to deform.
