IIRC the haze if its on the inside of the windshield is caused by gasses leaching from the vinyl dash material. It happens on all vehicles with this material. On my vehicles I use Stoners glass cleaner with a microfiber cloth & it seems to work well.

Well, another rainy morning and I can still see the haze. On Sunday, I had used some Royal Purple Engine Cleaner/Degreaser on it, then took it to the carwash. Again, it seems incrementally better, but still there.

@Kenv47 - It's not on the inside. You can see where the wipers smear it around, but never seem to completely wipe it off.

Pretty pervasive stuff you got on there. The only thing I can think of is that it's some sort of silicone based lubricant that somehow got on the windshield. I searched for a little bit on how to remove silicone lubricants and oils and almost everyone says it's near impossible to completely clean it off.


Not saying that this is your case, but it's the only thing I can think of.

Try polishing it just like you would the paint, as long as this haze is on the outside, I do it as a part of my detailing maintenance. I clay the glass and use a medium to fine polish, keep in mind glass is way harder than clear coat. Wipe down with 70% alcohol to remove polish oils if that don't work may want to look at the possibility of a defective windshield. Also if you apply something like rainx or even wax or sealant it can haze pretty bad and be a bear to remove, there are glass coatings available.

While driving around last night in the rain (the haze was most noticeable in this scenario), I was thinking that it did seem much better, so I'm going to try another round or two of cleaning with the Royal Purple degreaser, or maybe some KrudKutter, and using some microfiber cloths this time around instead of regular paper towels. Hopefully another round or two of a strong cleaner will get the remainder of it off.

I had tried the Invisible Glass spot remover, which I thought would be a type of polish, but not a regular paint polish. I thought someone else mentioned they tried claying with no success, so I didn't go there. I generally don't use RainX, and have also been avoiding the option for any of the extra 'sealants' that the car wash offers to make sure that they weren't just making it worse.

Oh, I would (and will) absolutely try a regular paint polish! (I just haven't had a chance to try it yet.) I'm the guy who tried clay and thought it did great, but just as you've found, once it dried up and you drive it a bit, you notice there's still that film or whatever the hell it is stuck on there. I'll be putting the D/A buffer to work on it soon (I hope. Friggin' job and home life keep getting in my way!)

0000 steel wool. Is it overspray? It sounds like it is. Try the steel wool. If you use 0000 steel wool it will not scratch the glass
