Default Inside windshield issue, un-removable residue?

Hi all,

My GF recently got a new car and the windshield has something on it, it looks like it may have come up through the VENTS.. like maybe the heater core went??

Whatever it is, it won't come off with solvent's.. It's looks vapor like, almost like a glass shower door that never comes completely clean.

You can REALLY see it at night, it distorts the light..

Any thoughts??

I think i know what your talking about. My car as well as my gf's car has the same problem... the only thing that i found that helps is just to get a dry micro fiber towel, or any towel and scrub hard w/ no cleaners... when i did it, it removed most of that junk.

Also, it might help to do it on a cold morning, when there's a little condensation on the inside glass.

....off-gassing of the plastics/materials in the interior. My new Challenger is one of the worst I have encountered as far as the rear glass is concerned. The residue is quite stubborn and I'm still wrestling with it to be quite honest. .....it doesn't help that the angle and location makes it difficult to clean regardless. Some cars are simply worse than others IME. As for the other windows, it simply takes quite a bit of scrubbing/effort with a towel as mentioned. The initial residue may need something else though to cut through. In most cases an APC or solvents have worked for me. Unfortunately, you're somewhat limited as to what you can try since it's on the interior of the glass. ....and the last thing you want to do is make a mess. If I run across something in my quest for a solution to my rear window woes, I will definitely let you know.

Use a damp chamois. That is the only thing I've found effective for removing the "haze" without streaking.

if the above doesn't work, and any cleaning you do doesn't work, the glass may have a defect, I've read a thread about a windshield that had defects that have..."stuff" in the glass so it doesn't look crystal clear which the OP eventually got the windshield changed

I have the same thing...even when you hit it with Stoners Invisible Glass the stuff comes back a week or two later. I just keep cleaning it hoping it'll diminish with time.

use this. it is a chore trust me. my car has some sort of hard water stains i couldnt even get off with a razor blade on the inside. this metal polish states on the back that it polishes glass too. you have to put some ass in to it and it will leave a horrific oily stain. let it dry for about 15min or so and thus begins the 3 to 4 attempts of cleaning the glass with invisible glass (or the kick ass glass cleaner that subaru makes that i steal from work, it is also a chrome polish!)

Tell me about it. The residue that haunts. Personally, I think Stoner's is part of the problem, however. I know the stuff is equivalent to walking on water in this community, but I never remember this problem on any of my old cars using Windex. Curses to tint!

....I highly doubt that's it. It is far more likely that it's the plasticizers in the materials/components of the car that is causing it as I mentioned before. IME, sometimes the initial film/residue can be a little more resilient and difficult to remove (always leaving streaks, blotches, etc. no mater how hard you clean). Once you get the surface of the glass clean though, I have found that it is easier to maintain and the off-gassing eventually diminishes to the point where it is no longer such an issue.

I hope the metal polish works for you. I would suggest throwing a towel over the dashboard though when working on the windscreen. ....you don't want the polish or applicator to accidentally contact it and possibly stain the surface/finish.

I had to clean mine several times the first few months, but it came off without too much trouble for me. I also figured it was plastics, and it eventually went away.

I've read that a dealer will clean it for you, if you dare.

Careful about vinyl shine/etc, the sun will cause it to coat the inside of your windshield. Used to happen to me all the time when I used armor all (I know...) - now I just clean the vinyl and use a very light coat of vinyl protection.

vinegar and even the fumes will eat away the tints adhesive. i would not use that same with ammonia.

I was about to suggest using one of those Mr. Clean Magic Erasers, but I'm not sure how safe that is on glass. I'm gonna try a spot test this week just to find out.

Use a vinegar solution, maybe 1 part vinegar, 2 parts water. I used it occassionally for this problem. Obviously wipe everything down as much as you can afterwards and make sure its dry. Follow with a cleaner of your choice. I never had a problem with it eating my tint with this method.

Also, you may want to try an old clay bar those things work wonders for several issues.

I have this problem too. Ill try a couple of these solutions to see if they help. I would not try the magic eraser though. It works by creating microabrasions not good for glass.

i found that out lol. used it on my headlights! but the cleanup guy at work did a quick polish and wax and now they look even better than before! so definatly dont use a magic eraser on paint! it may be ok on glass since its so hard, try a tiny spot first.

Im taking delivery on-new WRX and was wondering if this interior window haze is something i should expect or a "10%" thing..?

Any thoughts on things I could maybe do to keep it from happening..? Ill be parking nightly in my garage -- maybe keep the windows rolled down to let any possible vapors let off by the new plastics roll out of the car rather than get bottled up 8-10 hours a night..?

Thoughts..? Expectation setting..?

YMMV, but IME this has been an issue with every new car I have purchased in recent years. Yes, you can try leaving the window(s) rolled down to see if that might help but expect that you will begin to notice the haze likely every 1-3 weeks (depending on your tolerance level). As time goes by however, the degree of haze diminishes as does the need to clean it off. In most cases I have noticed a fairly dramatic drop-off in the fist 3 or so months and then a slow regression until it finally becomes almost a non-issue. Either way, you’re going to have this problem in almost any new car you buy these days (to some degree or another).

Hey guys, reviving the dead... again.

I've just had a new windscreen installed, which may be a coincidence, as I also live in the tropics and we've just had our first rains of the summer, but I have the dreaded film.

I've not had a go at it yet, aside from using windex and some special windscreen wipes (see: not that special), but I was just wondering what people have used to remove the film from "off-gassing" or "vinyl fog"?

This is not a new car, although I am pretty liberal with the protectants and whatnot (love my car).

I recently bought a new diving mask for snorkelling and the guy who I bought it from recommended using white toothpaste, the gritty type, specifically NOT the gel...
And scrubbing the hell out of the glass on the mask with it.
I thought that was rather obscure, but several divers have since confirmed it, with some even recommending using n actual toothbrush to scrub it in with.

Perhaps this could work on my windscreen? Food for thought, anyway.

Other suggestions I've heard include acetone and even steel wool in a very fine grade.

This one seems to cause the biggest arguments, despite glass being physically harder than steel. I've spoken to a few detailers who say throw a towel over the dash and use acetone and 0000 steel wool and then windex or something to clean it...

Sounds like a bit of a mission, what are people's experiences?

What works best / easiest?
