What is the best method to remove formaldehyde from a car?

Car formaldehyde removal methods include opening windows for ventilation and using vinegar to eliminate odors. Below are the relevant details: Opening windows for ventilation: To accelerate the dissipation of harmful gases, the most effective method is ventilation, though this process is time-consuming. Due to the car's narrow and enclosed space, new cars should frequently have their windows opened for air exchange. If possible, doors should also be opened. Using vinegar to eliminate odors: Vinegar can adsorb formaldehyde and also stabilize it. Placing some vinegar in the car not only provides excellent adsorption effects but is also cost-effective and easy to use.
The most effective method to remove formaldehyde from a new car is ventilation combined with high-temperature treatment. After picking up the car, I parked it in a sunny spot with all windows fully open for at least 3 hours every day for a consecutive week, as high temperatures accelerate formaldehyde release. I placed six 200g activated charcoal packs under the seats, replacing them weekly—activated charcoal is highly effective against free formaldehyde. I also purchased an in-car air purifier online, specifically a model with formaldehyde detection to monitor concentration levels in real time. However, the most crucial step is to minimize using air conditioning with windows closed during the first three months. One test showed that formaldehyde concentration increased by over 50% after just two hours in a sealed environment.
To deal with formaldehyde in new cars, I mainly rely on a combination of physical methods. First and foremost, it's essential to open the windows frequently. Keeping the windows open during commutes is more effective than using an air purifier. Secondly, I stuff coconut shell activated charcoal bags into the seat crevices, focusing on the dashboard and trunk areas. Every week, I wipe the interior surfaces with a white vinegar solution, as the acidic environment helps break down formaldehyde. Recently, I've also tried photocatalytic sprays, but it's important to choose products with official test reports. The most surprising discovery is that sun exposure is particularly effective—two hours of midday summer sun can achieve results equivalent to three days of ventilation.
