Why does a car still have odors after more than two years?

[Alex]

There are several reasons why a car may still have odors after more than two years: 1. Leather odor: If the leather treatment is not done properly, it can produce a pungent smell. 2. Floor mat odor: You can purchase two charcoal bags and place them under the front seats and near the air intake of the blower to help reduce the odor. Methods to eliminate odors: 1. Simple ventilation: Keep the windows open while driving, and avoid completely closing the windows when parked—leave a small gap to allow odors to dissipate. Therefore, try to avoid keeping the windows tightly closed and the air conditioning in recirculation mode for extended periods while driving. 2. Photocatalytic odor removal: Photocatalysts, such as titanium dioxide developed using nanotechnology, can help remove odors but may corrode materials like car seats and dashboards. They are specifically designed for indoor air pollution control. 3. Essential oil diffusers: Using plant-based essential oil diffusers can quickly eliminate odors, with noticeable improvements in just 15 minutes. This method is not only suitable for new cars but also ideal for vehicles that have been in use for some time and need air quality improvement.
