I was storing my windshields from cars with other my bricks. Now they are scratched, nearly not transparent just translucent. Is there a way to sanitize transparent parts from scratches?

Haven't tried this with Lego, but here are the first two things that come to mind.
Novus plastic cleaners (they make 3 solutions for various scratch depths, with Lego I would probably buy the one for the finest scratches) work well on my pinball machine plastics.
About the transparency, I would try the standard headlight cleaning solutions for a car.
You've got three different approaches: 1) products that fill the scratch 2) products that essentially dissolve the plastic material so that it re-hardens smooth 3) products that help you polish the scratch away
1) a silicon-based lens cleaner can do this and works for small scratches or some "cloudiness", but it won't be perfect for example http://www.northernsafety.com/Product/4190/Bausch-Lomb-Sight-Savers-Large-Disposable-Lens-Cleaning-Station-with-Silicone-Spray or a furniture polish with wax http://www.ehow.com/video_4791118_remove-scratches-plastic.html
2) it is likely that the Novus and similar products fall into this category, but they rely on polishing for the finish... similar to CD or DVD repair
3) here is a step by step method using household toothpaste http://www.ehow.com/how_5013183_remove-scratches-polycarbonate-lenses.html
