This product is perfect for those who are struggling with wiper blade streaking! It's a wiper sharpener. When your wiper blades deteriorate and cause poor water removal, you can easily repair them. Simply run the sharpener along the wiper blade, and the original water removal performance will be restored. It can be used many times, making it economical. You don't need to replace your wiper blades. The main body can be washed with water after use, so you can keep it clean at all times.
