Does a newly painted car contain formaldehyde?
2 Answers
Yes. Here are the relevant details: In fact, all types of paint contain formaldehyde, the difference lies only in the amount. Solution: It is generally recommended to ventilate a newly painted car for 24 hours before use. If you notice an unusually strong odor from the interior after the car has been painted, it is advisable not to use it immediately. When driving, it's best to open the windows and avoid using the internal air circulation for extended periods. If concerned, you can purchase formaldehyde test strips online to check if formaldehyde levels exceed the standard. If levels are too high, it is recommended to seek professional treatment at a specialized auto shop to remove formaldehyde. The hazards of formaldehyde include: irritation to the skin, respiratory mucosa, and eyes, leading to allergic dermatitis, skin itching, and triggering bronchial asthma, causing symptoms such as sore throat, cough, shortness of breath, difficulty breathing, itchy eyes, and tearing. It can also irritate the digestive tract, causing nausea, vomiting, diarrhea, bloating, and reduced appetite. Long-term exposure to formaldehyde carries risks of carcinogenesis, such as blood diseases, nasopharyngeal cancer, neonatal chromosomal abnormalities, colon cancer, and chronic poisoning leading to dizziness, headaches, fatigue, weakened immunity, neurasthenia, depression, and other neuropsychiatric symptoms. Cardiovascular symptoms may include chest tightness, palpitations, and shortness of breath.
A freshly painted car may indeed contain formaldehyde, as paints often contain various solvents, and formaldehyde is one type of volatile organic compound. When I bought my car, I did similar research—newly applied paint releases some chemicals during the curing process. Inhaling too much of these substances can cause dizziness or allergies, especially for children or elderly individuals who are more sensitive. The solution is simple: after getting the car, open the windows frequently for ventilation, and avoid tightly closing the doors and windows when parked to allow air circulation. If possible, park the car in an open area for a few days before taking long trips. You can also place activated charcoal bags inside the car to absorb odors. Higher temperatures accelerate the release of these chemicals, so extra caution is needed in summer—minimize staying in a closed car for extended periods.
