Hello, I have a 2005 Dodge Neon. The windshield looks like the windshield wipers have had a very fine grit sandpaper attached to them all these years.
The scratches are hardly noticeable - until night time. My vision gets very blurry. I'm assuming that these scratches are from a fine dust of some sort and are not gouges. So my question is, is there any product out there that can treat these types of scratches?
Some of the "glass wax" type products can minimize the scratches a little bit ... depends upon the severity of the surface. It's not very practical to polish the windshield out with abrasives to an optically smooth surface again.
But it's not that expensive to replace this windshield with a new one which eliminates the problem completely. If it's the original windshield, you've done well to have it last this long. Should be well under $200, installed ....
I had a thread up on this a couple weeks ago. From my research it looks like Diamondite is one of the better products available to do this. I have seen pictures on a few forums where people had successfully removed micro scratches and watermarks using this product. From what I saw through the pictures, the glass looked new. The most important part of the process is the buffing technique; you have go through a series of product application and alternating spin speeds, all the while ensuring that you don’t overheat the glass. If it gets too hot you will alter the structure of the windshield and distort the optics… people commonly associate the distortion to that of a “fun house” mirror.
As a temporary measure, I have applied car wax to the windshield. Works great. Not only did it mitigate the scratches but it also serves as a water repellent. Your results will vary depending on the wax. Again it is temporary... to truly renew the glass you have to planarize the surface and remove mineral deposits.

I've tried several things over the years on several vehicles and have found the most effective solution is to replace the windshield... given the time, effort, and materials I've tried it is probably the cheapest as well.

Depends on the scratches, but you can use clay bar, or jewellers' rouge.
You can also use cutting polish, in the UK we call it "T-cut", but I don't know what it would be called in the US.
You can use car polish on a windshield, but it's not really recommended as it can make the wipers smear and obscure view.
I have also heard of people using toothpaste, but I've never tried that one..
Essentially, anything which is very slightly abrasive.
