As soon as the temperatures fall below freezing, you can hear the familiar and unloved scratching on the car windows in the morning. The humidity of the night has turned into an almost impenetrable shell that covers the entire car. The consequences are the same every year: In order to be on time at work, not only has to get up rather, no, now you stand in the morning again shivering in the cold and scratch the windows free. In our guide, we show you how to defrost the discs in just a few seconds.

If you deceive just a little peep, you get in trouble! Because that is not allowed in traffic. You must defrost the discs in such a way that you are free both the windscreen and the side windows. But once on your heart, there are no alternatives "> Prevention is better than scratching!

The simplest and safest method is prevention. Protect your vehicle from the freezing wetness by providing it with a tarp or a blanket. Place these on the windscreen and clamp the ends on the left and right with the help of the car doors. The windshield wipers either lay on the ceiling or let them stand out.

It does not necessarily have to be a windscreen cover. An old rug or even a big piece of cardboard also serves its purpose.

Or you use a so-called semi-garage. These are available for little money in the trade. By the way, that's an advantage when snow announces itself. By removing the semi-garage you also save the laborious sweeping new snow masses.

Alternative means

However, you can also prepare the windows if there is neither a front cover nor a semi-garage at hand. So the deicing iron in the morning becomes a lightness:

  1. Mix 0.5L of lukewarm water with about 2 tablespoons of salt.
  2. Now use a sponge to spread the solution on the windscreen.
  3. Let it dry, ready!


  1. Mix vinegar and water in a ratio of 3: 1 (3 parts vinegar, 1 part water) in a spray bottle.
  2. Spray the mixture evenly on the slices in the evening.


  1. Rub the slices in the evening with a sliced ​​onion.
  2. The slices do not use ice.
  3. Disadvantage: Streaks may form and the odor is suboptimal.

The car is not completely free of ice, but significantly less ice is formed on the windows, if you have previously prepared them with the means just mentioned.

Hint: These methods only work if it is not too cold at that time and there are not even minus degrees.

  • Check to prevent:
    • Place a windscreen cover or blanket on the windscreen
    • use a semi-garage
    • Apply salt solution to the discs
    • Spray vinegar solution
    • rub with onion (with reservation)

Dust with ice spray

A classic that you also know very well: the de-icer spray from the trade. Handy, fast and unfortunately not very effective. Especially with cheap products many reach the opposite. While the ice layer thaws, the spray freezes in a very thin layer on the windshield again and the frustration is inevitable.

Better you mix the spray yourself. This is easier than you think at first, and this mixture will clear the slices in no time. In addition, it is environmentally friendly and your wallet is also happy.

  1. In a spray bottle, mix antifreeze for the slices with water in a ratio of 2: 1 (2 parts antifreeze and 1 part water)
  2. Then spray the mixture onto the glass and peel off the ice with the rubber lip of an ice scraper.

Alternatively, you can also use cleaning alcohol, ie isopropyl alcohol, instead of the antifreeze. The mixture should be prepared in the same ratio 2: 1.

The trick with the self-mixed de-icer spray is the higher alcohol . Alcohol does not freeze as fast as water, which keeps the glass free after spraying.

Sheathing disks from the inside

It is not uncommon for the discs to freeze from the inside. Especially with older car models and poorly insulated vehicles, this is part of the annoying everyday routine. Of course, there are also ways to counteract this circumstance a little.

  1. Avoid wetness in the car:
  • Tap snow off your shoes as much as possible,
  • store wet gloves and caps better in the trunk,
  • remove wet doormats from the car and let them dry while warm
  1. Ventilate the vehicle well:

Switch on the heater in the car and briefly open the doors so that the heat can escape with the moisture.

  1. Direct the fan directly at the discs.
  1. Use dehumidifier for vehicles
    This is a natural tissue that absorbs moisture from the interior. This method does not only help against icy slices. These do not fog up then!

Dehumidify yourself

You can also make a dehumidifier yourself.

  1. Take an old pair of stockings.
  2. Fill in a stocking cat litter.
  3. Tie the stocking together.
  4. Pull the second stocking over the first stocking.
  5. Put the little bundle on the dashboard.
  6. Studded discs are a thing of the past!

Tip: Never use chemical de-icer spray inside a vehicle!

Deice slices with water

Time and again one reads that disks are easy to de-ice with water. But beware! If you choose this method, never use hot or even boiling water. The consequences would be fatal. Due to the severe temperature differences between the disc and the water, the windscreen could jump or even burst.

Therefore, use at most lukewarm water:

  1. Fill in the evening a plastic bottle (optimally 1, 5L) water.
  2. Put the bottle on the radiator.
  3. In the morning, the water has an optimal temperature.
  4. Slowly pour the water over the front glass.
  5. The ice thaws in seconds and you have a clear view!

Tip: Ideally suited for older vehicles that do not yet have any technology in the windscreen.


As so often in life, prevention is better than action. If you have the opportunity to cover your car then this is by far the best method. The fastest and most effective way to defrost a car window is to use lukewarm water. However, opinions sometimes go apart here and there. Especially modern vehicles, which are equipped with a windscreen heater or other sensors, could be sensitive. If in doubt, talk to a specialist or car dealer.
