Are you annoyed by scraping ice on your car? A simple home remedy can help and make your winter life easier.
Kassel – According to meteorologists, it could get as cold as minus 20 degrees Celsius. Winter is hitting Germany with full force. For motorists in the south over the past few days, this has meant one thing above all: to plan plenty of time to clear the vehicle of up to 50 centimetres of fresh snow per day.
The masses of snow are one thing. But at the end of the day, the ice has to be cleared from the windows. Many use a classic ice scraper for this. But what if it's not at hand, or the ice layer is too thick?

Under no circumstances should you then pour warm water on the slice. There is a risk of cracks, in the worst case windows could even burst, warns the ADAC. For a window that is iced from the inside, a very simple trick is often enough.
Fortunately, there are also various tricks for the outer windows that make ice scraping easier and faster. A certain home remedy can be particularly helpful in this regard. And best of all, it also works without an ice scraper. The miracle cure for frost is a homemade de-icer brew.
Defrost a car window without an ice scraper – with home remedy vinegar it works in seconds
It's very easy to make. Mix vinegar and water in a three-to-one ratio (three parts vinegar, one part water) and pour the solution into a spray bottle. Simply spray the mixture on the icy areas and the frost will disappear within a few seconds.
The vinegar-water solution can also be used preventively when scraping ice on the vehicle. If you spray the home remedy on the car windows before the night, the windows will remain ice-free.
How come? Vinegar water freezes at lower temperatures than water. Although acetic acid already freezes at 17 degrees Celsius, the mixture does not. This is due to a phenomenon known as freezing point lowering. In the vinegar-water mixture, not only the water molecules must crystallize during freezing, but also the bonds to the vinegar molecules must be broken. This process consumes energy, which in this case means that it needs more cold.

However, the method with vinegar and water is effective only at moderate sub-zero temperatures. If the temperatures drop well below freezing, you can resort to high-proof alcohol (for example, washing alcohol or spirits, alcohol such as vodka is not recommended). Another alternative to scraping ice on car windows is a salt-water mixture. However, it is important to make sure that the salt is completely dissolved in the water before applying it to the disc.
More and more electric cars are being registered in Germany. Especially in winter, however, drivers with electric vehicles have to pay attention to a few things. YouTuber Bjørn Nyland also had to go through this painful experience.
