How to Deal with Frost on the Windshield in Winter Mornings?

Frost on the windshield can be removed using the defogging function of the car's air conditioning. The methods are as follows: 1. After the engine warms up, turn on the warm air from the air conditioning, activate the car's defogging switch, and direct the airflow toward the windshield surface to quickly disperse the frost. It is best not to use the recirculation mode at this time, and try to minimize the temperature difference between the inside and outside of the car to prevent fog from forming again. 2. Adjust the interior temperature to match the outside temperature as closely as possible, eliminating interior fog and allowing the frost to melt quickly. 3. Apply a thin layer of glycerin or alcohol to the windshield to prevent frost formation for a short period. Alternatively, mix dishwashing liquid with water in a 1:10 ratio, pour it into a spray bottle, and apply a thin layer to the inside of the windows. Once dry, this will effectively prevent fogging for a while. Finally, if frost forms on the windshield, stop the car to deal with it and wipe it clean with a dry towel. Avoid driving while attempting to remove frost or wiping it while driving to ensure road safety.
As an early-rising veteran driver, I've found the most reliable method when facing frosted windows is to first gently scrape off the surface frost with a hard plastic card or specialized scraper, avoiding excessive force that could damage the glass. Then start the engine, switch to the warm air setting and select defrost mode to direct hot air toward the windshield for faster melting. I always keep a spray bottle filled with warm water and alcohol solution handy - spraying this makes it easy to wipe away residual ice particles. For prevention, I cover the glass with an old blanket or professional cover every night to block moisture contact; during severe weather, spraying some antifreeze provides extra protection. Safety is paramount - never drive before completely clearing the windshield, as obscured vision can cause accidents. I also regularly check if wipers are frozen to ensure they're operational in emergencies.
