How To Stop My Car Windows From Keep Always Fogging Up Inside
79With the weather getting colder and wetter the hinderence of getting in our cars first thing in the morning with frozen fogged up windows is apon us. This isn't great when your late for work. So what can you do to stop your car windows from fogging up? The frost on the outside can be cured with de-icer. Its best to buy de-icer in liquid form than to buy it in aerosol. You'll get alot more for your money in liquid form. So your windscreen is de-iced but inside is fogged up. Most people if they are up very early in the morning will leave their car running on the drive whilst they get ready. This is a big no no. Theives now prey on people that do this, as they have the keys and car already running, all they have to do is open the door and drive off. Your insurance doesn't cover you either if this was to happen. There are fancy alarm add on's you can buy that will start your car from your alarm fob but still keeping your car locked and secure ( these are not good if your the type of person who leaves their car in gear all the time. ) its called auto start.
If your car steams up no matter what you do then here a few things you should do to prevent excess moisture building up and to maybe eliminate some factors. If you are always in a hurry and wipe the windscreen on the inside with a mit or tissue this could one of your problems. Doing this makes the windscreen extremely dirty and oily making it easier for the moisture to build up, so no sooner have you wiped it it steam up again. Try to avoid wiping your windscreen. Get some good window cleaner like 5 star rated Invisible Glass Cleaner. Rain-x do a windscreen repelent for the outside which I can not rate enough this stuff is excellent, it dramatically increases visibility on those journeys when your windows wiper can't keep up. They also do a window cleaner and repellant, this stuff is excellent also. By cleaning your windows you should dramatically reduce the moisture build up.
If your heaters inside your car never get hot then your problem may be that your cars thermostat has gone. The job of the thermostat is to stop water circulating around the engine until it reaches a certain temprature, thus making the engine warm up quicker. This is not just a benefactor for your heaters but is so that your cars oil reaches its operating temprature quickly. So if your heaters just never get hot then yur car needs a new thermostat. These are very cheap to buy and pretty simply to change any mobile mechanic should be to change your thermostat in under and hour easily.
Also feel your carpets for water or dampness if you suffer from your cars windows fogging up on rainy days even more than usual cold damp days, Check your footwell carpets. If they are excessivly wet then you may have a problem with your windscreen or crack/poor seal or your heater matrix is leaking. You can tell if your heater matrix is leaking as you will lose water in the header tank. A crack windscreen can be changed on your insurance if you are full comp.
The best thing to do is clean your windscreen with a good quality auto window cleaner like Invisible glassceaner and see if this reduces moisture build up. You will always get fogged up windows, older cars will suffer with it more due to them having less of everything. If your having problems with heat then you need to look more on the mechanical side of things and if your have water in the car then you'll never get rid of the fogging until you have cured the culprit. You can also buy 12 volt heater that plug straight in to your cars cigerette lighter socket and give instant heat.
Rain-x have a specific product in their range Rain-X AF21212 Anti-Fog which tackles the problem of fogging windows.
7 Things to remove/reduce your from fogging up:
- Clean all your windows properly internally
- Remove frost from your Windscreen quickly with a liquid de-ice
- Do not use a sponge or cloth to wipe it off
- Give yourself plenty of time to warm your engine up so your heaters can remove the condesation.
- Open your windows slightly if your clothes are wet to let the moisture escape. Put wet coats in the back or in the boot if possible to put the moisture at the back of the car.
- Check your footwells for puddles
- Replace a cracked or chipped windscreen

Being the owner of a V reg Citroen Saxo, I completely understand just how bad fogged up windows can get! With it starting to get colder here up north I'm even waking up to find ice on the inside of the windscreen! - Quite irritating if you haven't given yourself enough time to de-ice the car!
I wasn't aware that a water-repellent window cleaner (such as Rain-x that you mention in the post) could actually help, but i guess its certainly worth a try! Thanks for the information!
Hi JP993 thanks for the info, i have a old Subaru Brat Pick Up truck and its for ever fogged up. It is getting some what annoying but i'll try you rain-x suggestion and hopefully problem solved. Just joined Hub Pages. Already enjoying it and only joined an hour ago.
Your right the truck is old first registered in 1993. I checked it last night after reading you hub and the seal around the drivers door is not good, as far as the floor goes its plastic lined so doesn't hold damp. Going to sort the seal out to day and i think it might just sort it out. Thanks for the advise!!
Hi I own 3 cars ranging from 1962 (Chrysler) to 2004 - the best ways to reduce the moisture is to make sure the heating setting is on fresh and NOT recirculate. This will reduce the amount of condensation that builds up in the car as your driving and stays in a vapour form and then comes out again on the windows once the inside of the car cools down. It will also prevent/get rid off the fogged up window effect as you drive.
opening up windows slightly has helped me
Guys just set the heating system on fresh - not recirc it works - I live in one of the wettest dampest climates on the planet and my windows are dry and see through nearly all the time - once the heater warms up wooosh no moisture - it works as does cleaning with vinegar and water to keep that film off the inside - for the outside use a good commercial product to keep the road grease to a minimum - have not used this one but sounds good and by the posts it gets a good support too
I'm going to try this today!
This annoys me more than anything on earth, I hate the experience of driving with fogged windows!!

Hi there, the problem you write about is universal and not confined to Blighty. Here in Spain we also have this annoying situation and so do many thousands of others. Nevertheless a useful and informative hub and I for one thank you for it.
