Why Doesn't the Car Wiper Clean Properly?
2 Answers
When a car wiper doesn't clean properly, it could be due to issues with the wiper arm angle or hardening of the wiper blade and aging of the rubber strip. Below are the relevant details: Issues with the wiper arm angle: If the wiper blade is in good condition but still doesn't clean properly, the problem might lie with the wiper arm angle. Adjusting the wiper arm can resolve this issue. If the spring is too tight, you can loosen the distance between the springs. Hardening of the wiper blade and aging of the rubber strip: Long-term exposure to sunlight, wind, and rain can cause the rubber strip of the wiper blade to harden and age. When the wiper doesn't clean properly, the primary reason is often the aging of the rubber strip. In such cases, you may need to replace the rubber strip depending on the situation. Additionally, there might be dirt on the wiper blade. Check and clean any dirt if present.
I often ponder over these things while driving, and I've found that most cases of ineffective wiper blades are due to the aging of the rubber strips. Over time, exposure to wind and sun hardens and cracks the rubber, leaving streaks when wiping water. Another issue is oil stains on the windshield, accumulated from road exhaust or improper car washing, making the view blurry. Cleaning the windshield with vinegar water or a dedicated cleaner can help; don't hesitate to replace the wiper blades—I usually change them every six months, and silicone ones are more resistant to high and low temperatures. In summer, covering the windshield with a sunshade can reduce rubber aging, and in winter, using antifreeze wiper fluid prevents freezing. Make it a habit to regularly check the condition of your wipers; clear visibility during rain is paramount for safety, as neglecting minor issues can lead to major problems.
