car windshield scratches and white marks?

Posted: 29 Dec 2013 05:06 AM PST

Hi, please see a link to a picture of my windshield. I bought a car, it was a cloudy day and i didn't notice the state the windshield was in. But as soon as the sun came out I saw loads of small white spots of various sizes. Does anyone know what they are and how to get rid of them? https://dl.dropboxusercontent.com/u/995582/car/2013-12-28%2011.39.56.jpg thank you.
