Will exposing a new car to direct sunlight accelerate formaldehyde removal?

Exposing a car to direct sunlight does not remove formaldehyde. Not only is it ineffective, but it may also cause plastic decorations to release more formaldehyde and other harmful substances. Whether it's a new or old car, prolonged exposure to sunlight can damage the car's paint, interior, and plastic components. Effective methods for removing formaldehyde: 1. Open windows for ventilation: This is the most effective method, applicable both indoors and in vehicles. Due to the confined and small space inside a car, new vehicles should frequently have their windows opened for ventilation. 2. Remove packaging: New cars often come with plastic packaging that should be promptly removed. If not removed in time, it can hinder the release of harmful gases. Moreover, plastic itself is a harmful material that can emit toxins at certain temperatures. 3. Use activated charcoal: Activated charcoal, being a solid material, is small in size and can be placed anywhere. It also helps in odor removal and formaldehyde absorption, with decent effectiveness.
From the perspective of having driven for twenty years, I deeply understand that sun exposure can indeed accelerate the removal of formaldehyde in new cars, as high temperatures cause chemicals in interior materials to volatilize more intensely. However, relying solely on sun exposure isn't enough—you need to combine it with opening windows for ventilation. Otherwise, formaldehyde will just accumulate inside the car, making the air even more unbearable to breathe. When I first got my new car, I specifically tested this: after half a day of sun exposure, opening the windows for half an hour significantly reduced the pungent odor. Conversely, if the windows were closed during sun exposure, the temperature would soar to over 50 degrees Celsius, and the smell would become even more overpowering. I recommend parking in a spot where you can leave the windows slightly open and avoiding direct midday sunlight to prevent plastic interior aging or damage to electronic components. Formaldehyde release in new cars can last for several months, so remember to use activated charcoal bags for absorption and regularly clean the interior. This approach protects both your car and your health—a win-win situation.
As a meticulous car owner, I would like to remind you that although sun exposure can accelerate the removal of formaldehyde in new cars, it comes with risks: high temperatures may cause the interior to release more harmful gases or damage genuine leather seats. From personal experience, after a day of sun exposure, the odor inside the car worsened, and the color faded. A safer method is to park in the shade, leave the windows slightly open for natural ventilation, avoid strong midday sun exposure, combine with regular cleaning, and use eco-friendly products like bamboo charcoal bags. Be patient, as formaldehyde will dissipate slowly. The air quality while driving affects both mood and health, which should not be overlooked.
