Should You Open the Car Windows When the Car is Parked Under the Sun?

[McAsher]

You should open the car windows when the car is parked under the sun. Here are the specific details about parking a car under the sun: 1. Principle of Sun Exposure: First, close the windows and let the car be exposed to the sun to heat up the formaldehyde gas inside to a certain extent (accelerating the movement of formaldehyde molecules). Then, open the windows to allow fresh air to circulate, thereby expelling the harmful gases. As for the duration of keeping the windows closed during sun exposure, generally three hours is sufficient. However, this does not mean the car should be continuously exposed to the sun, as prolonged exposure can accelerate the aging of interior seats and even release more harmful gases, which would be counterproductive. 2. Precautions: Be aware that canned beverages like cola are filled with compressed carbon dioxide gas. Under prolonged exposure to sunlight, the gas expands and can easily cause an explosion. It is advisable to choose beverages in paper packaging or non-carbonated mineral water to ensure the safety of the car's interior.
