Why does a five or six-year-old car still have odors?

[DakotaMarie]

A five or six-year-old car may still have odors due to various smells such as glue, leather, plastic, or smoke, which can compromise the air quality inside the vehicle and make it substandard. Below are the reasons for odors in the car and their solutions: Specific causes of odors in the car: It could be due to residues from eating or smoking in the car; or smells emitted by the interior in humid climates; it might also be caused by a long-uncleaned air filter that has become moldy and bacterial, producing odors. Simple ventilation to eliminate odors: Open the windows while driving to ventilate, and when parked, do not completely seal the windows—leave a small gap to let odors out. Newly purchased cars will inevitably have some odor, so avoid keeping windows tightly closed and the air conditioning on recirculation mode for extended periods while driving. Frequently opening the windows for air exchange is the best method. If parked for a long time, it's advisable to leave a small gap in the windows to allow odors to dissipate quickly. Precautions: When placing fruit peels in the car, replace them regularly to prevent them from rotting in the enclosed environment. Some car owners should avoid placing whole fruits directly on the dashboard or near the windshield to prevent potential hazards while driving.
