How to Deal with Frost on Car Windows in Winter?

1. Built-in Defroster: You can use the car's built-in defroster by first turning on the AC button inside the car, then switching the air circulation mode to the external circulation mode. However, this method will increase the car's fuel consumption and is not suitable for long drives. 2. Opening Windows: While opening the windows to remove frost is quite effective, it compromises comfort during winter. The biggest advantage of this method is that it saves time and does not increase fuel consumption. 3. Turning on the Heater: Turn on the car's heater and adjust the airflow direction to blow directly onto the windows. The warm air will effectively dry the air inside the car, which helps the frost disappear. However, this method has its drawbacks as well. When the car has just started, the water temperature hasn't reached the normal level, making it difficult to quickly remove the frost on the windows.
I usually use a hard card to scrape off frost. On my way to work, if I find the car windows frosted, I just grab a bank card to scrape. First, start the car and turn on the heater to blow warm air at the windshield, then use the card to scrape slowly from top to bottom without applying too much force to avoid scratching the glass. If the frost is too thick, pour some room-temperature water on a towel and wipe it—never use hot water as it can crack the glass. Later, I got smarter: before parking at night, I lower the window slightly before closing it to leave a gap, or cover the windshield with an old bedsheet, so the next morning I can just pull it off with no frost at all. Keeping a de-icing spray in the car also helps—it costs just a few dozen bucks and lasts the whole winter.
