Wind Shield Problems

[wetcat007]

My windshield has an issue where any wiper blades will REALLY drag along the surface and not work smoothly at all, it's not the blades I've tried different blades. I've tried rainx multiple times on it and it has not helped any, short of replacing the windshield is there anything I can do?

Is your windshield wet? or dry?

Scrub it with a good cleaner and one of those plastic dish scrubbers. It likely has some tough dirt or coating on it. It probably has sap on it. Sap is often hard to detect on the glass because it's almost clear and can be in very small droplets, and it will make even new blades perform poorly.

Polish it with a random orbit buffer and glass polish.

Is it badly pitted as well? If so, maybe you should cut your losses and replace it.
