Can Exposing a Car to Direct Sunlight Remove Formaldehyde?

[OBarrett]

Exposing a car to direct sunlight can help remove formaldehyde, but prolonged exposure may cause damage to the vehicle. Below are some methods for removing formaldehyde: Method 1: The most common way to remove formaldehyde from a car is by opening the windows for ventilation, which is almost cost-free. Try to keep the windows open for extended periods, and you can also use an electric fan to accelerate air exchange between the interior and exterior. However, ventilation alone cannot completely eliminate formaldehyde; it only serves as a supplementary measure. Method 2: Using activated carbon is one of the most widely adopted methods for formaldehyde removal in daily life, and it is relatively low-cost. However, activated carbon tends to reach adsorption saturation quickly. Once saturated, it needs to be replaced or sun-dried. Additionally, if the amount of activated carbon is insufficient, it won't be very effective in removing formaldehyde.
