Why is there a bad smell inside the car?

[NevaehLee]

The reasons for bad smell inside the car are: 1. New car odor: Chemical substances that have not yet dissipated exist in the interior plastic panels or rubber rings of the vehicle; 2. Air conditioning odor: Bacteria and dirt accumulate when the air conditioning filter is not cleaned for a long time. Precautions to avoid odors: 1. Avoid eating strongly scented food in the car; 2. Do not store odorous items in the car; 3. Use the external circulation mode when running the air conditioner; 4. Remove the plastic protective film inside the car promptly after purchasing a new car. If the smell inside the car is strong, you can use bamboo charcoal bags or grapefruit peels to absorb the odor, and open all the car windows to let the odor dissipate.
