What to Do When There is Frost on the Car Window?
4 Answers
Solutions for frost on the car window: 1. If you find frost on the windshield, start the car first; 2. Warm up the car sufficiently to allow the engine coolant temperature to rise; 3. Once the engine coolant temperature has risen, turn on the heater and set it to blow upward toward the windshield mode, which can speed up the warming of the front windshield; 4. When the heater melts the frost on the outside of the glass, you can gently wipe the frost with a car cleaning cloth to accelerate the melting process; 5. After all the frost on the outside of the glass has melted, use the windshield wipers to clean the water stains on the glass surface.
As someone who often rushes to work, I find frost on car windows really troublesome. Before heading out in the morning, I start the engine in advance and turn on the heater to blow warm air at the windshield. After a few minutes, most of the frost melts. Meanwhile, I use a rigid frost scraper to carefully remove residual frost from inside the car, being gentle to avoid scratching the glass. If the frost feels too thick, I spray some commercial de-icer to speed up the process. Importantly, never pour hot water or use a blade to scrape, as extreme temperature differences can easily crack the glass. For prevention, I try to park in a garage or cover the windshield with a protector, especially in winter to avoid outdoor parking. This daily routine takes only 5 minutes, ensuring a safe, worry-free, and unhurried drive.
After years of driving, I believe preventing frost is more efficient than dealing with it afterward. I make it a habit to check parking spots beforehand, preferring garages or shaded areas to minimize exposure. If parking outdoors, I use a sturdy windshield cover, which almost eliminates frost by morning. On rare occasions when frost appears, I avoid rushing to use tools—instead, I start the car and let the defroster gradually melt it away. I also wipe interior surfaces with a soft cloth to prevent moisture recurrence. Regular maintenance of the heating system ensures its efficiency. These small actions collectively reduce morning hassles significantly, making driving more comfortable and safer—especially for long distances with clear visibility.
In the morning when I find frost on the car windows, I immediately start the engine and turn on the defroster mode with medium fan speed to avoid excessive heating of the glass. Then, I use the plastic frost scraper kept in the car to gently remove the frost layer. If I'm in a hurry, spraying some de-icer spray will speed up the melting process. At the same time, I make sure to clean the inside of the windows to prevent fogging. This process usually takes about 3-5 minutes, during which I use the time efficiently by doing other preparations like checking the tires. The key is not to drive during this period to avoid accidents caused by obscured vision. Safety always comes first, and developing this habit makes driving much more reassuring.
