Does exposing a new car to direct sunlight accelerate formaldehyde removal?
2 Answers
Exposing a new car to direct sunlight does not accelerate formaldehyde removal. Here are effective methods for removing formaldehyde from a new car: 1. Ventilation: Opening windows is the most effective method, applicable to both indoor and vehicle spaces. Due to the confined and enclosed nature of a car's interior, it's essential to frequently open windows or doors for ventilation whenever possible. 2. Promptly remove plastic packaging: New cars often come with plastic packaging that should be removed immediately. Delayed removal can hinder the dissipation of harmful gases, as plastics themselves contain harmful substances that may emit toxins at certain temperatures. 3. Use activated carbon or bamboo charcoal bags: These solid materials are compact and can be placed anywhere in the car. They effectively absorb odors and formaldehyde. Products like Qingyi Activated Carbon are highly recommended as they can be reused multiple times.
Exposing a new car to direct sunlight can indeed accelerate the removal of formaldehyde. High temperatures promote the faster release of formaldehyde from materials like plastic and leather inside the car, much like how wet clothes dry quickly under the sun. I tried this when I bought a new car—parking it under the scorching summer sun for two or three hours made the interior smell noticeably lighter when I opened the door. However, relying solely on sun exposure isn’t comprehensive enough; it’s more effective when combined with ventilation. I recommend cracking open the windows or sunroof while parked to allow airflow, while also avoiding prolonged exposure that could damage the paint and interior. If materials degrade, they might release even more harmful substances, which would be counterproductive. Regular ventilation during daily use, especially running the car for a bit before driving when it’s cold, ensures safety and peace of mind. If you’re in a hurry, placing activated charcoal bags inside to absorb odors can also be quite effective.
