What is the reason for the odor inside the car? How to deal with it. The following introduces the relevant reasons and treatment methods.
1. Reasons for the odor inside the car
(I) Interior materials related
Volatilization of plastics, rubber and other materials: A large amount of plastics, rubber and other materials are used inside the car, and these materials contain organic solvents, additives and other ingredients. During the use of the car, especially when it is hot in summer, these substances will evaporate into the air due to temperature changes, causing odor in the car. This situation is more obvious in new cars because the chemicals in the interior materials are not completely volatilized. The source of this odor is caused by the characteristics of the interior materials themselves.
(II) Personal habit factors
Food residues in the car: If you eat in the car, food residues may be left in the car. Over time, these residues will deteriorate, resulting in unpleasant odors.
The impact of smoking: When smoking in the car, various substances in the smoke will adhere to various parts in the car, and the smoke itself is difficult to dissipate. Long-term accumulation will make the car full of odors.
(III) Air conditioning system problems
The air conditioning filter is dirty: The air conditioning filter is responsible for filtering the air entering the car and preventing dust and other pollutants from entering the car. When it is not replaced for a long time, dust and dirt will accumulate, leading to bacterial growth. When the bacteria decompose and mold, it will produce a sour smell.
Evaporator mold: The evaporator is a key component in the air conditioning system, responsible for separating condensed water from the air. If the evaporator is moldy, it will release odor. Even if the air conditioning filter is replaced, if the evaporator is moldy, the odor will still exist.
II. How to deal with odor inside the car
(I) Ventilation and ventilation
Window ventilation
Diagonal window convection ventilation: Opening the windows diagonally can make the air in the car convect, thereby removing the odor in the car faster and more effectively. This method is simple and easy, and does not require additional costs.
Ventilation when parking: When parking and the weather is good, you can open all the windows to allow fresh air to flow fully in the car to reduce odor. Ventilation for about 15 minutes to half an hour each time will have a good effect. This is one of the most basic and effective ways to remove odors in the car.
Air conditioning hot air drying: Using the heating function of the air conditioner, the evaporator is cleaned and dried through the circulating airflow. Without disassembly, the odor caused by the air conditioning system can be eliminated, making the air in the car rejuvenated.
(II) Adsorption
Activated carbon (bamboo charcoal) adsorption: Activated carbon (bamboo charcoal) has a strong adsorption capacity and can remove formaldehyde and other odors. Placing it in the car can continuously purify the air for a long time. It should be noted that the newly purchased bamboo charcoal bag should be unpacked and used as soon as possible.
Place natural adsorbents
Grapefruit peel, orange peel: These peels have a strong ability to absorb odors and can also emit a fresh fragrance, which helps to improve the air quality in the car. It can not only absorb odors in the car, but also make people feel happy.
Leaf and soil deodorizing bag: This deodorizing bag can continuously absorb odors and will not be saturated. It can be used as a long-term odor absorption solution.
(III) Cleaning
Replace the air conditioning filter: If there is an odor when the air conditioning is turned on in the car, it may be caused by the decomposition and mold of the air conditioning filter. At this time, the air conditioning filter should be replaced in time to prevent dust and dirt from accumulating and bacteria from growing.
Cleaning the evaporator and air conditioning duct: When it is determined that the odor is caused by the mold of the evaporator, it is necessary to clean the evaporator and the air conditioning duct to completely remove the source of the odor.
In-car cleaning: Keep the car clean and tidy, clean up debris and cigarette butts in time, and avoid food from being exposed to the high temperature environment in the car for a long time, which can reduce the generation of odor from the source.
(IV) Other methods
Use car air conditioning deodorizer: If there is an odor when the car air conditioning is turned on, you can use the air conditioning deodorizer to clean the air conditioning duct to remove the moldy odor caused by long-term use of the air conditioning. At the same time, you can also use the deodorizer in the car to achieve a good deodorizing effect.
Deodorizing with edible vinegar: Edible vinegar can not only remove stains, but also neutralize harmful substances such as formaldehyde, thereby removing odors in the car. When the vehicle is not in use, you can mix vinegar and water and spray it on the seats and doors, then wipe it clean with a rag.
Place fruit to deodorize: Place fresh fruits such as lemons, grapes, pineapples, etc. in the car. Their natural fragrance can effectively neutralize the odor in the car and create a natural and fresh atmosphere. The deodorizing effect of cut fruits is better.
Ozone disinfection method: Use a special disinfection machine to send high-concentration ozone into the car through air conditioning circulation, quickly sterilize and disinfect, provide safety protection for the car environment, and thus eliminate the source of odor.
Use a negative ion purifier: Purchase a negative ion air purifier, which can not only remove odors, but also provide fresh air and improve the driving experience
