Here’s a surprisingly simple trick. No special equipment or expensive products are needed. You only need two very common ingredients: water and rubbing alcohol. Mix one part water with two parts alcohol in a spray bottle, then leave it in your car.
In the morning, a few sprays are all it takes: the frost disappears almost instantly. No need to scrape for ages or leave the engine running for several minutes. It’s quick, convenient, and particularly effective for defrosting your windshield effortlessly.
How this solution actually works
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.
