So being so cold as it is. My car doesn't see the sunlight, and therefore there is condensation forming on the inside of the windshields. I could get most of the ice out by placing the heater direction towards it , but that still leaves the back windows that are almost untouched and ice formed.

Is there another way to remove ice from the inside if the sun doesn't shine on it?

    "Inside" means inside the car, or inside your garage? If the former, why is there ice inside your car? If the latter, then why not do as Zack recommended, and use an ice scraper?

  • Ice scrapers from inside don't work as the windows are concave Commented Jan 19, 2015 at 20:52

If you have excessive condensation inside the car you need to dehumidify your car interior... You can use those dehumidifying boxes with silica gel crystals or I have seen a suggestion of using kitty-litter gel crystals knotted inside an old sock and sticking it on your back shelf or dashboard.

I presume the dampness arises from wet passengers dripping water on the carpet/upholstery rather than a leak. You could try sticking the heater on full blast with the windows slightly open to dry it out on a long journey.

My car has an electrically heated rear window so its less of a problem for me. On previous cars I have used an ice scraper on the inside, but they work less well as the curvature is "wrong" - concave rather than convex.

  • Thanks for the reply. I did try the scraping of the windows from the inside. But you're right it didn't occur to me that car windows are usually concave. Commented Jan 14, 2015 at 19:21
  • Uncooked rice also works well at removing moisture, and can be filled in a sock as you suggested. Commented Jan 19, 2015 at 21:17
  • wouldn't uncooked rice go mouldy once it got damp?

It happens a lot here in Canada since we have long and cold winters. I tend to use a plastic card from my wallet. It can bend to the shape of the window which is concave inside. It's not very fast and it's pretty annoying but when you are in a hurry it's better than heating the car and waiting for it to melt.

I suggest using a card you don't use often instead of a credit or debit card because sometime the card can snap or bend and the magnet stripe might be damaged.


Take the largest container of the hottest water you can carry. If the water from your tap doesn't get very hot, consider turning up the max temperature on your hot water heater temporarily. Otherwise, boiling it on the stove might be your better option.

Take this container and slowly pour the water over your car window, being careful not to get any on yourself of course.

The heat from the water will transfer to the window, melting the ice that's formed on the inside.


Take a hand warmer, or a microwaved rag, and wipe the ice away with it. The heat will melt away the ice.

    A word of caution. I've seen the "hot water on frozen windscreen" trick lead to a broken windscreen due to thermal shock. Use a large amount of warm water rather than small amount of hot water.

  • My dad used to do this when we lived in Maryland. He stopped when he moved to Michigan because of the fear of hot water breaking the window.

  • For me, this water froze and lead me to have a nice layer of ice on the outside of the windshield that was nearly impossible to scrape off with my scraper. I was still trying to get that off long after the heaters had cleared the inside humidity. The best is to use the heaters and be patient, then leave the windows open a crack in the future so condensation can escape.

You may need to give the inside of your windows a good clean. Condensation tends to form around the small particles of dirt on the screen. If you are prone to wiping away condensation with a cloth/sleeve etc., you'll be making the problem worse and worse. In cold weather, this condensed water will freeze.

So prevention may be better than a cure. Give your windows a good clean and polish and hopefully this problem will occur less often.


I had this issue with my 2006 Tundra and its sunroof. The sunroof sealing system is designed with passive drainage and the weep holes can get plugged up, which allows water to overflow/seep inside the cab. Use an air hose to blow out weep/drain holes in corners when sunroof is in open position. Also, close heater vents to "recirculate" option when weather is both sunny (warm) and rainy/cold, which can cause a condensation situation. The recirculate setting shuts down the outside airflow into the cab.


If you have frozen water built up on the inside of your car windows, while keeping your heat on, you can run your air conditioner with the setting that lets fresh air come in. The AC will help dry out the air on the inside of the vehicle and prevent it from fogging up and freezing.


With my precious golf3 I had the same problem, the moist was creeping in and staying there; even though it got away for day or two after driving for hours with AC set on hot (not too pleasant btw.) it kept getting moist all over again.

Doing something against this may mean replacing the rubber sealings of your doors or similar, but maybe it is just a one time thing for you, in this case one of the things I tried was:

Put some bricks into the oven, set to highest temperature, and leave it there for quite a while. Then quickly put them into some container that withstands the temperature (steel bucket in my case) and put it into the trunk of the car. Removing anything that blocks the air flow (hat shelf, flip over the rear seats if you can). Start car, set AC to really hot, and do not completely close the trunk (just so much that you could stick a scredriver through the gap).

If you get the amount of bricks right, it will quickly heat up the back of the car, causing most moist to evaporate. Hot dehumidified air from the AC will enter at the front and leave at the back, drying out the car pretty well.

The number of bricks depend on your ovens temperature and your cars size. Do not use too many or you might seriously damage something (a lot of stuff in a car doesn't like anything more than 50°C)

  • Thanks. Although a good idea. I don't have a industrial strength oven, or even bricks. Commented Jan 19, 2015 at 20:54
  • @JeffJaffery: Doesn't need to be industrial strength. Most consumer grade ovens can do 250-280°C and some have a self-clean overheat mode for far over 300°C (which can be used in another life hack to do great pizza)

I was thinking of using a hairdryer (like the handheld electrical ones) to just warm up and blow the water away. However, the water might drip into the car.
