How to make your windshield wipers look like new again


First, raise both windshield wipers into the upright position. Insert the key, turn it to power on the system (but don’t start the car), then turn the power off again and remove the key. Next, gently push down the wiper lever on the right side of the steering wheel. At this point, both wipers will start rotating and stop in the upright position. Now you can manually lift the wipers—effectively standing them upright. The two wipers are of different lengths, so be sure to remember their respective positions and make sure you don’t reverse them when reattaching them. Use your left thumb to press down on the square clip of the wiper blade, and with your right hand, pull firmly in the direction indicated to remove the wiper blade. You’ve now successfully removed both wiper blades. Next, get a piece of 2000-grit wet sandpaper. You can find wet sandpaper at paint stores—it’s very inexpensive, and one sheet should last you several years. Tear the wet sandpaper into small pieces; just one small piece is sufficient for each use. Soak both the wiper blades and the wet sandpaper thoroughly with clean water. As you work, keep the wiper blades moist and use the wet sandpaper to carefully grind the rubber strip of the wipers. Remember: the rubber strip of the wiper is like a kitchen knife—you need to sharpen not only its two sides but also the sharp edge on the front surface. This process doesn’t take long—about five minutes should do the trick. Now, reattach the wipers. Be careful not to mix up the positions of the short and long wipers. Once installed, turn the power back on and gently push down the wiper lever again—the wipers will return to their original positions.

Common Wiper Problems

Strip-shaped streaks: The optimal support point for the wiper blade was not found, resulting in the wiper blade failing to make full contact with the glass at every point. Improper arm pressure, damage to the upper structure, or even an improperly fitted wiper blade can all cause this phenomenon.
