What are the methods to remove odors from cars?

[VanDavid]

Methods to remove odors from cars are as follows: 1. Open windows for ventilation. If the car is newly tinted and windows cannot be opened for the first few days, odors will accumulate inside. Prolonged driving under such conditions may cause dizziness and headaches. Therefore, unless it's smoggy weather, slightly opening some windows for natural ventilation works very well. 2. Place activated charcoal in the car. Put several large bags of activated charcoal both in the front and back to effectively absorb odors. However, every once in a while, the bamboo charcoal bags should be placed under direct sunlight for more than 2-3 hours to restore them to like-new condition. 3. Purchase an air purifier. Keep an air purifier in the car. During smoggy or dusty weather, turn on the internal circulation and the air purifier to block some external pollution. 4. Use the air conditioning to remove odors. If window ventilation is not possible, use the air conditioning's external circulation to maintain smooth airflow inside the car. The air conditioning should be cleaned regularly, as it can also accumulate harmful gases.
