A windshield related problem.

I washed my car for the first time today (took delivery two weeks ago) and after the wash, I noticed a one inch long scratch (I hope it's not a crack) on my windshield. It's hairline thin but I can feel it with my finger nails.

I don't think it's caused by a flying stone or windshield wipper (never used the wipper because it hasn't rained). Nobody has touched the windshield either. A friend suggested it could be a scratch at the factory. Anyone else having this sort of scratches on their windshields? I am a bit puzzled as the car is otherwise well assembed. Except the steering wheel is not quite straight, I haven't found other issues with the car.

The scratch is small but now that I realized it's there, it bothers me. Any quick fix to make it go away?

Thanks.
