How to Deal with Water Marks After Using New Wiper Blades?
2 Answers
New wiper blades leaving water marks can be addressed by cleaning the windshield with glass cleaner, as it might be due to an oil film on the glass. This oil film has strong water adhesion and is difficult to remove even with the wiper blades' action. The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. The wiper uses a DC permanent magnet motor, typically integrated with the worm gear mechanism when installed on the windshield. The worm gear mechanism serves to reduce speed and increase torque, with its output shaft driving a four-bar linkage that converts continuous rotational motion into a left-right oscillating motion.
I just replaced my new wipers and encountered the issue of water streaks left after wiping, but I managed to solve it myself after some time. Initially, I thought the wipers were faulty, but upon closer inspection, I found a layer of oil film and dust on the windshield, especially thick along the edges. I took out a dedicated automotive glass cleaner and thoroughly wiped the glass from top to bottom with a soft towel, then rinsed away the debris in the gaps with clean water. After testing, the water streaks were significantly reduced. I also adjusted the wiper arm position to ensure better contact with the glass surface, which improved the performance further. Usually, I make it a habit to clean the glass during regular car washes to avoid blurred vision during rainy drives, which could compromise safety. New wipers sometimes require a break-in period; wiping a few more times can help improve performance. If water streaks persist, it might be due to poor-quality wiper blades, and switching to a reputable brand could offer better durability. Safe driving should never be taken lightly—poor visibility increases the risk of accidents. Remember not to operate the wipers on a dry windshield to avoid damaging them.
