What are the methods to remove formaldehyde in a car?

Methods to remove formaldehyde in a car: 1. Open windows frequently for ventilation and use the car's external air circulation; 2. Place bamboo charcoal bags to absorb formaldehyde; 3. Clean leather seat covers, floor mats, etc. inside the car; 4. When the car is not in use, place a small bucket of water with some vinegar in the car - water can absorb formaldehyde while vinegar helps stabilize it; 5. Visit an automotive care center for negative ion deodorization service. Formaldehyde is an organic chemical compound, a colorless gas with a pungent odor that irritates human eyes, nose, etc. It can be easily reduced to methanol with metal or metal oxide catalysts, and oxidized to formic acid or carbon dioxide and water.
Last year I bought a new car, and the strong smell inside was really bothersome, especially with the excessive formaldehyde levels. To tackle this issue, I spend a few minutes every day ventilating the car by opening the windows before driving, especially after it's been parked for a long time, to allow air circulation. I also placed several bamboo charcoal bags in the seat crevices and trunk to absorb formaldehyde molecules. I find that sun exposure works quite well—on weekends, I park the car in an open area with the windows open for a few hours, as the heat accelerates formaldehyde release. Occasionally, I spray lemon juice or a diluted white vinegar solution on the interior surfaces, avoiding harsh chemical cleaners. The key is consistency; don’t expect immediate results. After several weeks of these efforts, the odor noticeably diminished, and I feel much healthier. While driving, I ensure proper ventilation by avoiding closed windows with the AC on, which helps reduce formaldehyde buildup.
As an environmentally conscious person, I prioritize natural methods for removing formaldehyde in my car to avoid chemical pollution. Ventilation is the simplest and most effective approach—I've developed a habit of opening the windows for a few minutes every time I enter or exit the car to promote air circulation. I place formaldehyde-absorbing plants like spider plants or pothos in car corners, as they naturally purify harmful substances. I've also tried using coffee grounds or orange peels as odor absorbers, which are low-cost and eco-friendly. Sun exposure accelerates formaldehyde volatilization, but care must be taken to prevent interior aging. Homemade solutions like diluted vinegar for regular interior wiping help break down residual formaldehyde. The key is consistency—intensify these practices during the first few months of owning a new car to genuinely purify the cabin environment, protecting both myself and the planet.
