Streaky windshield, new wipers not helping...
....Ok, this sounds like a dumb question, but I have a problem I cannot solve.
My windshield is always "streaky". I thought it was just bad wipers, so I replaced them. It was better, but still not perfect. Within two weeks, they were streaking just as badly as before. I have not used cheap blades, they were rather expensive.
My only conclusion is that there must be some type of oil, or chemical on the windshield. My truck is always clean, and I always wipe down the glas when I wash. Regular car wash soap is not removing the problem.
Do any of you have an idea of what this might be? If so, anybody have an idea on how to solve it?
Is it possilble there is some sort of "windshield polish" out there that I may purchase? Should I just use some paint polish with my porter cable 7424?
I will appreciate all replies.
