Windshield cleaning

[boostedmoose003]

For some reason on my car the windshield seems to have some sort of film that doesn't really go away with glass cleaners. I've tried a few different brands and it looks clean in sunlight then all of a sudden there is a weird streak/haze in it. This is the only car that does this when I clean the windows. Should I try a mild clay or fine polish to see if this fixes it?

I tried using Meg's Glass cleaner, Stoner's, and Optimum. I spray and clean with a waffle weave glass towel. This is the same thing I do on my other vehicles with no problems.

Well when you drop those names, something is definitely awry but a picture is worth a thousand words. Maybe the towel used has residues from a detergent?

Did your car come from the factory with a "fog eliminator" option for the front windshield?

I don't know too much about them but I do remember that someone else had problems with the surface coating (it is electrically conductive) making the inner surface difficult to clean.
And once damaged the windshield had to be replaced.

I could never figure out why anyone would want something like that since I have always been satisfied with the defroster. Then I read a report about why it was created in the first place. Instant defrosting, way before the engine would produce enough heat to warm the defrost air.

Alcohol and a magic eraser.

You can try a polish like has been suggested or any Cerium Oxide polish (CarPro Ceriglass for example). I've never used it, but I've seen people talk about Duragloss Nu-Glass positively as well.

I thought it my be the towel at first because I used one I have been using for a bit and changed it to a new one and still the same. It's only on the exterior as well on my s2000. I usually never have a problem with windows but this has me baffled. I'll see if I can get a picture tomorrow if a fine polish doesn't do anything. Should I try a mild clay before going to a polish?

Do you drive it on the freeway much? Idle on the freeway in heavy traffic? If so, try not to drive behind city buses, semi-truck's, etc. They spew raw diesel out the exhaust when under load (heavy acceleration). The diesel gets on your windshield and makes it smeary and difficult to clean.
