This mixture's effectiveness is no accident. Alcohol has a much lower freezing point than water. This weakens the ice layer, making it easier to remove from the glass. This process naturally speeds up defrosting and also limits frost reformation for a short time, which is especially helpful on very cold mornings.
Are the expensive alternatives really worth it?

There are many de-icing sprays available commercially. While effective, they are often expensive and quickly consumed. This homemade solution offers comparable results at a negligible cost. In a context where one is trying to be budget-conscious, this alternative proves particularly appealing.
Prevent frost rather than having to deal with it every morning
Going further also means trying to prevent frost from forming. If you don't have a garage, a simple trick can reduce humidity inside your vehicle. Fill a sock with cat litter and place it on the dashboard. It will absorb ambient moisture and limit fogging and frost when you wake up.
This method may seem surprising, but it is recognized for its effectiveness, especially during very cold nights.
The little things that make a difference in winter

Remember to raise your windshield wipers before driving at night, check the condition of the seals, and ventilate the car for a few minutes after each trip. These simple actions, repeated daily, improve driving comfort and facilitate rapid defrosting of the car throughout the winter.
Because a good winter morning is often one where you hit the road without stress, ready to face the day with a smile.
