Does your wiper leaves mark on windshield?

It was raining hard lately in Cali and I have been using the wiper a lot. But today when I wash my car, I notice there are 2 marks on my windshield. It only comes up when the windshield is wet. If you dry it out you can't see it.
I tried to clean it really hard but it's not coming off at all. If I wet it with some water it would appear again. The marks appear where the two wipers stop and go back down.

I think everyone have this same problem, but we probably don't even notice it. If you don't believe me, next time when you try to clean the windshield, you will see these marks when it's wet. I don't have any camera with me right now or I would of take some pics.

I'm worrying that the wiper blades might of scratches the windshield or something. I also notice it makes a lot of noise now when using them. I might get a new blades because these unremovable marks tell me that's there is something wrong about the wiper blades.

 

Try using a microfiber cloth, dampened with washer fluid. Wipe the blade a few times, turn the cloth, and then do the other blade.

There's probably dirt/grime build-up on the blades thats causing the marks on the windshield.
