Clean Clear Windows

Hello all. So I recently got my windows tinted, and to clean off the windows I used this cleaning product called FW1. I used that for my old car and the windows turned out really clear and streakless. For some reason it was not the case for the forester. Now, the fall/winter is here so the temperature outside dipped, the last couple of weeks ranging from 40s - 60s degrees. I started noticing this thick layer of haze all over my windshield. Defogger did nothing to remove it. So I went out and bought Invisible Glass. Worked nicely for a day and the haze is slowly coming back. Both of these products have
failed me. I don't smoke, I haven't cleaned the dash so these are the only products I used in the car, and I rarely let the windows down. Does anyone have a solution and can remommend a window cleaning product that will give me spotless, streakless, CLEAR windows? This haze is driving me crazy, literally, I'm driving around constantly staring at this annoying haze that's keeps coming back. Please help...

I keep a specialized cloth for cleaning glass in the door pocket to dry clean the inside of the windshield when I see the haze on it.

Also confirm the haze is on the inside and not must forming on the outside.

I have no idea if this is a good idea but acetone comes to mind. it is a solvent so it will cut anything that is oil based and it dries very quickly, so I doubt it will leave streaks. Its probably find on bare glass but personally I wouldn't use it on tint out of fear that it might melt it. I have also used invidible glass and found that it works pretty well, although I think blue windex also works quite well, its more about the rag you use.

Invisible glass is a tougher solvent than windex so if that didn't work, I don't think windex will either. I have a microfiber towel in the car and I had to wipe the windshield every other day for the last week and a half. I'm sure the colder temperature is the culprit here...if any one else has any other suggestions please let me know.

Grab a roll of paper towels, micro fibre or other cloths can retain soap residue from washing and can cause smearing and haze as it just doesn't clean the glass enough. All I use is Invisible Glass and paper towels and have no issues. I use a quantity of paper towels, once saturated grab some fresh sheets.

When you rub the haze with your finger, does it feel a little slimy? Any smell of coolant? The haze sounds like you could have a small coolant leak which is evaporating into the cabin when you turn on the heater.

I doubt if this DIY formula will solve your problem, but it's great for regular glass cleaning:1 cup distilled water, 1 cup alcohol, 1 tablespoon white vinegar. Put in a spray bottle along with a label.

I have a haze issue too.

My theory is that it's the soap from the washer place that has a little wax in it. (it could just be road grime build up though) When the wax starts to wear off...haze. I removed it with a wax and grease remover but it was not an easy job.

is the haze on the tint or the window?

if its on the tint perhaps its defective?

other things to check. Recirculation.

try running in defrost mode.

Does the haze feel dry or moist.

Get a new terrycloth or glass microfiber.
rub the haze.. if it doesnt remove it dry it might not be "haze"

you dont list your location but in my area the recent weather has caused me to use defrost almost continuously for last 2 weeks.

infact it was so bad I would pull out of the garage and my windows and mirrors would instant fog. I've have to wait 2-3min for the car to warm up enough so the defroster would take it off.

Did you shine up your interior with anything? Armor all type stuff. It will evaporate and deposit on your windows.

In the first few months when my XT was new there seemed to be a similar material on the inside of the glass. No window cleaner seemed to touch it. Tried Windex, Simple Green, Method, vinegar/distilled water/ dish detergent, and it persisted. Whatever it was it caused the windows to fog up especially easily. But after many cleanings it finally got better, and now, a year later do not notice it. Assumed it was some product of outgasing of plasticizers from the interior, probably from the car sitting in the sun on the dealer's lot for some time. Seems to be gone now, maybe it outgased to somewhere else. Still having trouble keeping the inside of windshield clean enough for my OCD standards, even with a microfiber glass cloth, distilled water and vinegar with tiny amount of Dawn dish stuff there are always streaks. Part of the problem is that the inside of the windshield is so awkward to clean.

You used FW1 cleaning wax on your tint? That could be the issue. It states it can be used on glass or other non-porous surfaces (including NON-porous plastic). Tint, however, is porous. That's how the bubbles, haze and moisture dry out of it after application and how it can be removed so easily with an ammonia solution. You just let it soak in to loosen the adhesive.

i used the fw1 on the windshield, not the windows with tint. in fact, the tinted windows are not experiencing any of the haze issue. the windshield and the moonroof are the only ones affected by it. after using invisible glass once with a brand new microber towel, the haze did come back but it wasnt as bad.

recirculation is always off when trying to get rid of the problem.

i dont think anything is leaking (ex. coolant), this car is only 2 months old, so i definitely hope nothing is leaking...

i will continue to use invisible glass with paper towels instead microfiber towels to see if there is any difference. im hopeful that it will be better.

I always use Stoner's Invisible Glass. Tried RainX window cleaner, it works similarly. My method is to use a clean microfiber towel to clean the glass, then use another clean microfiber towel to wipe off almost immediately after application using the first towel.

If the towel used to clean the glass contains some sort of "quick detailer" solution, it will haze the glass eventually. My solution is to use a clean microfiber towel, and re-clean with Invisible Glass.

If cleaning at night, I try to turn on all available lights around the vehicle when cleaning the glass. If I don't I will surely miss a few spots and will see them the next morning.

yep thats exactly what i did. i have done it twice now, last time being only 2 days ago. the weather has warmed up a bit (60s-70s) and i havent seen any haze on the windshield. im certain the cold weather is directly related to it.

I've seen this on my 21 day old 2016 Premium. I find that I can just wipe off the haze with a dry microfiber towel. Occasional use of the defrosters, but the weather here in NJ hasn't been too cold so far this winter. (did I just jinx myself and all other residents of NJ??? :chair: )

I tried invisible glass for the first time this weekend, and I thought it did a good job. No haze issue, but it's only been one day so far!

I didn't really like the way the microfiber towels worked to clean the glass. I will try just plain old paper towels next. I did read that using newspaper worked great for glass, but I'm not brave enough to try that on my new car yet! Anyone try newspapers? Results?

Stan.

I attached two photos to showcase how bad the haze got. Left is cleaned, right is hazed up. The photo is only doing half its justice.

After using invisible glass with 2 microfiber towels (one to wipe after spray, and the other to wipe off any left over streaks/spots), the haze is gone. Had to do two sessions. The weather is still 60s - 70s here in Dallas, TX. I can see the haze appearing very slowly but it's still pretty clean. Invisible Glass works!

The haze on the winshields of a new car that keep forming is from the plasticizers in the new plastic parts of the car outgassing. One way to minimize it is leaving the windows cracked until its a few months old. My wifes crosstrek did the same thing and it slowed after a few months. The plasticizer is what also gives the cars that new car smell.

Looks like someone earlier mentioned the same thing. I learned a lot about this when i was at UMASS for a plastics training class for injection molding. Armorall and other protectants are plasticizers/ sealers and outgas also
