Do wiper blades need cleaning?

Windshield wiper blades do require regular cleaning to maintain their optimal performance. It is best to use a foam cleaner or mild detergent with a soft cloth to gently wipe the surface of the rubber strip, avoiding the use of hard objects or dry wiping which can cause rubber abrasion. When cleaning, lift the wiper arm to a 90-degree angle and rinse stubborn stains along the direction of the rubber strip, while also paying attention to cleaning the rear window wiper. In daily maintenance, avoid prolonged exposure to sunlight to prevent rubber aging; try to park in shaded areas or use a sunshade when parking. It is generally advisable to replace them every 6 to 12 months. Additionally, cleaning the windshield is equally important. Before use, ensure there are no hard objects such as sand or gravel on the glass surface, and use windshield washer fluid for lubrication to reduce friction. These measures can extend the service life of the wipers and ensure clear visibility and safety when driving in rainy conditions.
