Why does my windshield keep fogging up?
Windshield fogging up outside because of condensation when the temperature outside the car is much different than the temperature inside your car. Try to match the temperature inside your car to the outside temperature as closely as possible to reduce or eliminate fog or condensation.
If you live in a cold climate, you’re likely to use your car’s heater to stay warm, which can cause fog to build upon the inside of your windows. However, it’s possible to have the opposite problem in warm, humid climates when you turn on the air conditioning.
How to Defog My Car Windshield in Winter?
If you don’t want the inside of your car to turn into a scene from the Titanic, it’s important to follow these steps in order to defog your windows successfully:
The fog in the winter will usually form on the inside of the car and windows. Here I would recommend switching on your heating to the highest setting.
Turn the AC on as well. The hot air in the car holds moisture, and the air con can pull that moisture from the air and pass it over the evaporating coils.
Once again, I’ll advise you to turn the recirculation button off, and this will allow for dry air to enter inside the cabin.
If you want to aid cold airflow inside the cabin so you can exchange humid air for dry air, the quickest way to do that is to open a couple of windows slightly. You only have to do this for a few minutes.
Another way of doing this if you don’t want to open up the windows is using the defroster feature (if your car has one). Turn it on and wait for the hot air to evaporate the moisture from your window. Once again, the recirculation needs to be switched off! If you leave this function switched on, the heat inside your car or the air con will reuse the air on the inside instead of pulling dry air from the outside.
How to Defog Car Windows
During the winter season or perhaps when you are driving in icy rain, you'll notice fog the windows. Often in bigger cars, say a Chevy Suburban, this happens at the front of the vehicle where the passengers are sitting, and smaller vehicles like hatchbacks often fog up quicker all around. The best way to clear these foggy car windows is with a steady supply of dry, hot air. Activate your car's air conditioning and turn up the heat, once the temperature from the AC has increased, select the windscreen vents, and watch the magic happen. Cold, fresh air will actually have the same effect, so if you don't have a working AC, crack a window and set your vents to circulate air from the outside instead of recirculating cabin air, this will diminish the humidity within the cabin and clear up the windows.
Wiping the windows down with a dry cloth or your sleeve isn't very effective as you'll likely just gather the moisture that's there and spread it around. Plus, because the temperature in the car wouldn't have changed, the condensation will just reoccur. Your breathing will also simply counter the efforts.
Defog car windows spray
Alcohol is another great way in which you can defog your car window. Make this DIY care defogging solution by:
- Mixing 1 part water to 2 parts ethanol or rubbing alcohol.
- Shake together.
- Place this solution into a spray bottle and spray it on to the windshield and/or car windows.
This is definitely the quickest way to defog your car windshield and, because alcohol is so low in temperature, it will not freeze if you leave it in the car like some other products might.
The Science of Why Car Windows Fog Up
Ever wondered why your car windows fog up? The reasons are more numerous than you might assume, but this much is certain: Most drivers don’t enjoy trying to navigate roads and highways with a foggy windshield or windows. Fog impairs your vision, making it hard to see when driving in the daytime and at night. And, of course, virtually nothing is more dangerous than being unable to detect what’s in front of you.
Reasons for foggy windows include:
- Temperature: A temperature difference between the inside and outside of your car can lead to moisture build-up, increasing the potential for fog.
- Air quality: Cars manufactured after the year 2000 feature cabin filters that regulate air quality. Older cars or vehicles with faulty cabin filters may struggle with window fog.
- Passengers: The more passengers in your vehicle, the more likely your car windows will fog up. This fogging happens because of passengers’ breath and body heat.
- Dirty windshield: Dirt and debris attract water particles. So if your windshield is not clean, it’s more likely to fog up.
Do you use hot or cold air to defog a car windshield?
You should only use hot air to help evaporate the moisture from near your windshield, but this is a temporary fix. To prevent fog, use cool air to lower the temperature on the inside of the car glass.
There you go! Now you learned how to defog your windshield. Now what you will read the rest of the information is often asked by people who seek the main subject as you do. Keep reading!
How Do I Stop My Windows From Fogging When It Is Rains?
Fog on the window as well as the car windshield is because during a cold and wet weather, as it is when it rains, the car on the inside is highly humid.
This causes condensation on the glass surface, both laminated and tempered glass of the windshield and car windows, and this is the fogginess that causes impaired vision through either the windshields and the car windows.
One way to get rid of the fogginess is to turn your AC system on and set your car temperature to be as cold as it is out there.
This will ensure that the level of humidity in the cabin is controlled thus there is little condensation forming on the glass that impairs vision through them.
You can then use a clean and dry cloth to wipe off the fogginess that forms on the car windshield.
Turning on the AC will ensure that no more fog forms on the glasses.
Why Is My Windshield Fogging Up On The Inside?
During a cold weather, and maybe a damp weather, most car windshield will be fogged.
This is because on the inside of these cars is highly humid and this condenses on reaching the surface of the windshields.
This is because the windshield is cooled and causes condensation when the moisture reaches the surface of the windshield. This is what forms the fogginess as seen in some windshields.
How Do I Keep My Car Windows From Fogging Up In The Summer?
- Open the car windows and let the warm air from the outside into your car. This creates a sense of balance in the temperature of air both inside and outside your car.
- Another effective option would be using quality windshield wipers to clean the fog that forms on the outside of your car windshield. Wipers, the quality type, are designed to clean the car windshield on the outside effectively and hence leave them free from annoying fog that impairs vision through the car windshield.
- Getting a quality and top performing defrost would be another great solution to get rid of the frost that forms on either side of the car windshield. This would work effectively and you should be comfortable if you are not affected with the heat that utilizes in offering the end results.
- Other great solution ideas are setting the AC system to match almost the temperature on the outside or even drive with your windows down. The former would work well if you do not want to open your windows because of dust getting into your car and other factors. Having your windows down would be a great idea if you are in for a relaxing session.
Why Is My Windshield Fogging Up In The Summer?
During the summer, the outside temperatures are quite hot and it tends to be quite humid.
If you leave your car windows close for long this would lead to condensation on the car windshields because they have a lower temperature level.
How Do I Keep My Windshield From Fogging Up In The Winter?
The thing with the winter season, is that during the night a lot of fogging happens on the windshield and we wake up to a windshield that is not safe to drive in.
- One way to avoid this is leaving your car windows open for some time and let the cold air in. This gets rid of humidity in the car that would have otherwise led to the fogging of the car windshield. You should also take out bottles or open containers that might contain some moisture as they would increase the fogging extent on the car windshield. Defogging your car windshield during winter will need you to prevent the air inside your car from being too humid. This can be accomplished by first opening the car windows. It might get too cold, but you are probably dressed heavily for the cold weather.
- Secondly, turning on the AC system and setting it to a temperature almost similar to the outside would be effective in preventing the moisture from condensing on the inside of the windshield and causing the fogging. Preventive measures that would keep your car windshield from being fogged during the winter smearing the surface with shaving cream. This should be done on the inner surface and would prevent the condensation on the inside of windshield that makes the windshields less clear.
- Another simple and effective idea is to have a stocking or sock filled with kitty litter and leave it in the car overnight during cold nights. This would absorb the moisture that might have ended up forming on the windshield as fog.
Should I Use Hot Or Cold Water To Defog Windows?
Hot water would be effective in defogging the window as it has been seen to be highly effective in getting this done.
This would work for either sides of the windshield, provided you know what you are doing you will get the defogging completed in no time and the car windshield will be safe to use.
Does Shaving Cream Keep Windows From Fogging?
Yes, shaving cream is effecting in preventing your car window, as well as windshield from being affected by fogging.
Washing your car windows, windshields and even glasses with shaving foam is a simple yet effective way of keeping them free from fogging which makes it difficult for you to see through them.
What happens is that the shaving cream creates a protective film that covers the glass and keeps it from fogging.
Any soap would do the trick, but shaving cream is easier to apply. The protective film begins to wear away with time, but it will be effective for most parts of the day.
This solution would work if you realize that the car windshield is affected by the fogging and are not in a position to access defroster or any other solution.

Rating: Greg 28/11/2018 I read a tip for keeping your windshield from fogging up. Fill a sock with kitty litter and keep it in the car The litter soaks up the moisture that condenses on your windshield. I am trying it out tonight to see how well it works. OneHowTo Editor 28/11/2018 Hi Greg, Thank you so much for sharing. Kitty litter does work as a dehumidifier, but we have not specifically heard about it being used for this reason. Let us know how you get on so we can know if it works!
