scratching the windshield

The windshield of my vehicle is parallel to each other due to the wiper and there are about 100-150 scratches along the wiper line. No problem in normal weather, but it makes driving incredibly difficult in sunny weather. Anybody have this problem? I always used the original wiper in my car, I changed it every 8 months, but it's still incredible to have so many lines. Is there a way to fix this & nbsp ;? Because even if I bought new glass, I'm afraid the same & nbsp;

I have seen in the industry that the headlight and glass cleaning is done with a cake or a similar material, maybe this method may be a solution to your problem ....

I don't know if there is such a thing either ... & nbsp; http: //www.zaplat.com/video/nasil_yapilir/57482/Cam_Repair
