My car's windows get fogged up ALL the time. The defroster works for the most part, but I just don't want to deal with it several times a day. Any products or methods you guys suggest? How about using Rain-X? Let me know~ Thanks.

1. Hold breath
2. Use defroster all the time
3. Wear a jacket and turn on the a/c with defroster full blast and open ventilation system
4. Use the heater full blast with defroster and open ventilation system (takes longer)

i hear a tint helps with the defrosting

either that or drive around with all the windows down

Hmm... I guess you are either trying to be funny or you missed that I want a solution that lets me NOT use my defroster as often or at all.

Also, I should add... at first I thought it was me and/ or my passengers. However, today, after leaving my car in the parking lot for a few hours, I come back to see my car's windows all fogged up. It was a sunny day! Actually, I think it rained for about half an hour then got sunny again. Isn't that strange? It's like people were having sex in it before I got there! Haha excuse my inappropriate thinking...

rain-x anti fog stuff works

[kangta26]

Nothing wrong with using the defroster.. ?? Okay I'll try to be a little more helpful so i did a search..
From reading below.. maybe design of car, but simple reason it gets foggy.. I've used some anti-condensation products.. but the ones i've used seem to have their limits.. and need to be reapplied frequently.. I would think a waste..

ANSWER:
The windows in my car get foggy too, sometimes. It depends a lot on the weather and also the people inside and whether the air conditioning/heater is running.

Car windows fog up when water condenses on them. This can happen both on the inside of the window and on the outside. You can check to see in your mom's car where the condensation is because it will be wet to the touch.

It sounds like outside humidity might be a problem (especially on the East coast). It is here in Illinois, particularly on hot, stormy days in the summer. Water will condense on a surface if the temperature of the surface is below the dew point of the air next to that surface. So you need warm, humid air next to a cooler surface to fog up.

If it is very humid outside and you're running the air conditioner inside the car, water can condense on the outside of the windows. Using the windshield wipers and the rear defroster can get rid of condensation there by wiping it off or making it evaporate.

Often, the air in the car will be warmer than the air outside the car (this happens in winter here). Moisture will condense on the inside of the windows if the outside air is cooler than the dew point inside the car. This happened to me a lot when driving through a thunderstorm caused by an incoming cold front. In this case, running both the air conditioner, the heater, and the vents for defrosting the front window worked very effectively. The air conditioner dehumidifies air because water condenses inside it when the air goes past the cold tubes with the refrigerant inside. Heating it up way past its dew point makes it feel dry, and it is dry -- it'll help evaporate any condensation that's on the windshield -- and even more quickly the hotter it is because heat is needed to cause the liquid water to change phase to a gas.

*ps.. drive with a towel in the car.. that'll help wipey wipey..

rain-x anti fog stuff works

+2

[peachgirl]

Thanks, I'll try the suggestions.

[enteryourusername]

1. Clean your window thoroughly with Windex without ammonia. This actually helps a lot.
2. Apply some Rain-x anti fog (THis is in black bottle, not the outside yellow ones)

[taoh]

If you use Rain-X anti-fog make sure your windows really are clean and keep them clean as often as you can.

Also keep fingers/hands/dirt off the glass (Don't even think about wiping that fog with your hands).

[panda]

windex.

[Teh_Clique_Mob]

Keep a window open.

No tint really doesn't help. Maybe because its tinted you can see through it in the daytime better, but thats it.

Also, I should add... at first I thought it was me and/ or my passengers. However, today, after leaving my car in the parking lot for a few hours, I come back to see my car's windows all fogged up.

How come you don't want to use the defroster peachgirl? I mean thats what its made for. Is it broken?

Well anyway, fog will happen no matter what unless you use the Rain-X fog like the guys suggested. I think its called Fog-X.

If you have a defroster grid, check these:
breaks in the defroster grid
defroster fuse/all fuses
connections to the defroster grid
defroster switch

Find another environment to practice being "fit."
Anyways, there is a product on racingshields.com that has an anti-fog product. There are many anti-fog products. Just search on google.
Personally, I think the car's defroster is the best choice
