Two problems:

1. I am in FL (near Orlando) where the temperature varies between 70 and 100 degrees while the humidity is always more than 70%. When I drive at night or during very early morning (the temp is about 70-75) and have the AC on inside the car, the water vapor seems to condense on the outside of my windshield and gradually makes it foggy. The only way out of this, that I could figure out, is to turn on the heat on the windshield which gradually gets rid of the accummulated water vapor. But if I turn off the heat and turn on the AC, the problem comes back. This problem becomes all the more intense if it is raining which happens a lot too in FL. If I have to keep the heat on for quite some time, it becomes very uncomfortable for the passengers inside the car. Is there any other way to get rid of the condensation on the windshield?

2. I have never cleaned the inside of my windshield since I bought my car less than two months back. I find that the inside of the windshield has gotten a bit foggy which is clearly noticeable when I am driving in the dark, like at night. It is not noticeable when driving in the sun. This is different from the previous problem and I could not get rid of it by turning the heat on. Did you guys ever have this in your cars? Any idea how to get rid of it?

 

i have the same problem but what ive notice is just keep the windows down while u finish gettin ready or turn ur car w/ the ac on while u finish getting ready, it usually goes away in a min or so after i start driving. that is what i usually do and it help donest completely take it off but its somehting..its a pain... also when you wash ur car clean the inside of the windshield. i always clean the inside and outside when i was my car.

 

Last night I was driving with all my windows and moonroof open. But the fog on the inner side of the windshield was sooooo visible that it was difficult to see through. But today morning, in the sun, it is as good as gone. But if I try to see closely, it is still there but just not noticeable. Why does this happen in the dark?

Do you use any special kind of cleaner for cleaning the windshield? I heard there are cleaners that have fog removers.

 

move out of florida... that should help :-D

 

That will certainly help avoiding the problem, not solving it.

 

I will give you the best advice I have.

DO NOT under any circumstances use Rain-X Anti-fog treatment.

I too was tired of having fog issues so I applied it to the inside of my windshield. My windshield now looks like a smeared piece of really bad artwork. I have tried to buff it off to no avail. I have tried to take it off with windex multiple times. The stuff is like glue. If you are driving into the sun, your windshield is the most annoying thing in the world.

I say again, do not use Rain-X Anti-Fog treatment.

Wow! That really helped. I have been reading good things about Rain-X in the different forums and was almost thinking of trying it. Good that you posted this. I assume you used the Rain-X as directed.

The other thing that many people praise is men's shaving lather. Do you have any experience using it?

 

My opinion of the anti fog was the same BB, I can't recommend it either. You know I'm in Fl and have the same issue you have all the time.

On one window, I used my divers antifog solution. Jury is still out on that. I ALWAYS keep a microfiber cloth in my car just for this. It's worked well. I've done the similar trick for 11 years now, before with small, terry cloth washrag. BTW, if you do that, make sure you wash it using NO fabric softener, etc. Plain soap and water, air dry. My gf did my microfiber cloth with softener in the regular laundry, etc and that makes a much bigger mess than even the antifog stuff!!!!!!!!

 

Oh yea, philoforlife, stop by a photography store and pick up a small bottle of ROR. It'll fix you right up. Spray it ONLY on a cloth and wipe, do not spray it on the window. It will do very bad things to your dash, plastics, etc if you overspray.

 

I know that it works on mirrors not to sure about the wind shields

 

We get some really humid days and nights here in the the good ol' midwest and the fogging sometimes becomes an issue. What I have found is that you have to strike a balance between the a/c temp and the temperature outside. If it is 90 degrees and high humidty outside you can't have your a/c at 68 b/c the temperature difference and relative humidity difference is too great and then it gives you the condensation on the windshield. In my example, you would have to keep the a/c on auto and keep the inside temp at @ 77 or 78 and that should solve your problem and it will still feel cool and comfortable in the car. The a/c may switch between different exhaust vents and fan speed depending on the conditions it senses in the cabin. Also, make sure you are not recirculating the inside air but bringing in outside air through the a/c.

My 2 cents and I hope it helps.

 

Thank you!

One question...what is ROR?

Hah!

It will remove this crap from my windshield? I'm at wit's end!

Joshua

 

I have no experience with the lather.

The Rain-X called for spraying JUST A LITTLE on a cloth and wiping it on in a swirling pattern, followed by removing any excess by using a dry cloth or a cloth with some water on it. This was to no avail. Perhaps by a "little" they really meant .0001 microliters, because this stuff got everywhere and I only dabbed it on the cloth. If you look through my windshield into the sun you'll feel like your concluding a long and drawn out acid trip.

all the chemicals will continue to release from all the materials (aka new car smell) resulting in the annoying "fog" or film. best thing i found is use a lot stoners invisible glass and microfiber towels. then a month later repeat haha

and to prevent temp. fogging, always run the HVAC with the AC ON year round. keeps moisture out of the air. when "fresh air" comes in (windows open or AC off) that moisture sticks to the chemicals on the glass.

(thx 4 reminding me, mine is getting bad again)

hahahah ROFL htat is one funny pic... u r the king of sweet pics

 

Ok, here's my thoughts. THe Rain-X for the fog inside was a no no to begin with, sorry. Note the title of the product, "Rain-X", not fog-x. It's meant for the outside of your windshield to repel water and such, not the inside. Your inside "fog" problem is in fact normal and is just haze that forms normally. Windex or any window cleaner should do the trick, however I prefer the Invisble glass and mircofiber towel as well. Feel it works the best, however the newspaper trick works quit well too, just a bit more messy IMHO. Good luck getting the rain-x off, will come of over time don't worry.

 

Where do I get the Stoners invisible glass?

edit: Available at WalMart

 

If you would have read the post you would have seen that Rain-X is the brand which makes an anti-fog treatment for the INSIDE of the winshield. Called, oh gosh, Anti-Fog treatment. Google it.

ROR that's the name on the bottle. Residual oil remover. It's a compound for cleaning expensive photo lens'. Good, but nasty stuff.

I found stoners invisible glass at walmart. Tho we've only used it inside the house.
Link to ROR so you know what it is.

Anyone tried Stoners invisible glass with newspapers (instead of microfiber towels)? That seems to be a popular option to many http://www.contour.org/ceg-vb/archiv...php/t-753.html

 

Newspaper? What's that? lol, I get all my news on the net. I use a fine microfiber that I use to clean LCD screens and it works great. Gonna try it on my car windows tomorrow in the daylight.

Works great around the house too. TV screens, windows, mirrors. Better than windex.

 

Let us know how it works on your car windshield.

 

Josh, that's my mistake, I missed that minor detail. I take back the slam then, not that I meant anything by it anyway, but apologize none the less.

 

wow...ok this may sound crazy but if the condensation is on the outside of the window, why not try using the windshield wipers....

and if its really bad, windshield fluid could be used in a last resort case

 

You are right. The wipers do get rid of the outside condensation. However, this condensation mainly accummulates at the base of the windshield while a large portion of the upper windshield is completely dry. If I am running the wipers, they will go through the dry areas too, thereby wasting the wipers. I do that when the situation gets worse. But I was thinking there might be a more sophisticated way of handling this problem somehow using the climate control, etc. but it seems there isn't.
