How to Remove Heavy Plastic Smell in Cars?

Activated charcoal bags have adsorption capabilities and can effectively remove odors and formaldehyde with noticeable results. The advantage of this method is its convenience and speed. Sun exposure and ventilation make molecules more active and move faster, helping to expel unpleasant odors from the car while allowing fresh air from outside to enter.

I also encountered a strong plastic smell when I first bought my car, and tried several effective methods. Ventilation is the top priority: park in a safe place during the day with all windows open for air circulation, and driving for two hours on weekends can help a lot. Don't rush to use air fresheners to mask the smell—it can make it worse. I recommend placing activated charcoal bags under the rear seats or floor mats for strong absorption, and airing or replacing them regularly. Cleaning the seats and carpets is also crucial—a thorough vacuuming can reduce odor from dust buildup. If the sun is strong, exposing the car to sunlight for a few hours accelerates the volatilization, but remember not to leave valuables inside. Persist for a week or two, and the smell will fade—the key is patience, not rushing. The car is a place we often sit in, so health is no small matter.
