1. Simple ventilation and deodorization:
Test results: feasible! Buy a new car in six months.
When the Audi A3 window is closed, the narrow empty room makes the smell saturated, and the ventilation of the window makes the air circulate, which is simple and effective. When the car is opened in winter or exposed in summer, the unpleasant smell inside the car becomes more obvious. Because the release of formaldehyde and benzene will increase when the temperature is higher than 30℃, ventilation is indeed a feasible method.
Within one month of buying a new car, some measures should be taken to eliminate the odor inside the car. If it is summer, when the temperature inside the car is high, open the doors and windows regularly to exhaust the gas inside the car. If it is lower than 30 degrees, use the hot air in the car to heat the car. Remember to open the window every once in a while to get rid of the peculiar smell. However, excessive exposure will make the interior parts of the car aging and play a negative role. Open hot air several times in scattered spare time, and let this method circulate several times, which can speed up the discharge of odor in the car.
When parking, don't completely close the window, leaving a gap to discharge the odor. The new car you just bought can't avoid no smell, so try to avoid closing the window and circulating for a long time when driving. It is the best way to open the window frequently for ventilation. If you stay for a long time, it is best to leave a small gap in the window to let the smell out as soon as possible.
2. Photocatalyst deodorization:
Results: It is feasible, but it is best to operate in a professional institution.
Photocatalyst is titanium dioxide, which is a kind of photocatalyst developed by nanotechnology, but it is corrosive to the dashboard material of Audi A3 car seat and is specially used to control indoor air pollution. Various harmful substances are decomposed into water and carbon dioxide through surface oxidation reaction. The most effective way is to spray titanium dioxide first, then lock the doors and windows of the car, expose it to the sun for 2-3 hours, and then open the doors and windows for ventilation until the heat in the car disappears.
3. Essential oil aromatherapy and deodorization:
Results: it is feasible, but the effect is not great.
Aromatherapy with plant essential oil can quickly remove odor, and it only takes 15 minutes to feel that the smell inside Audi A3 is not pungent. But this method is not only suitable for new cars, but also for vehicles that want to temporarily improve the air quality inside the car. It should also be noted that there are two kinds of adulterated essential oils. The first one is soybean oil or lard, which is relatively poor. This essential oil is generally used for beauty adulteration, which will not harm the skin, but it has no effect. If used for aromatherapy, some will add essence. If the essence contains harmful substances, inhalation after volatilization will cause certain harm. If you add vegetable oil or animal oil, it will not harm your health!
4. Deodorization of fruits and plants:
Results: It was feasible, but the fixation was inconvenient and the effect was not good.
Plant deodorization is mostly used for indoor in addition to formaldehyde and other harmful gases. Because the empty room in the car is narrow, it is difficult to fix plants with pots, so this method is not recommended. Unless you can use a vehicle that has not been driven for a long time. Plants that can improve air quality are: chlorophytum, Eupatorium adenophorum and aloe. In addition, grapefruit, pineapple, oranges and other fruits not only have strong adsorption capacity, but also emit pleasant fruit fragrance, which can improve the air inside the car while removing odor. Many car owners need to pay attention to the fact that when putting these peels into the car, they need to be replaced regularly and in time to prevent fruits and vegetables from deteriorating in the long-term closed environment in the car. Some car owners should try to avoid putting the whole fruit directly on the center console or next to the windshield when putting it in the car, so as to avoid potential injury during driving.
5. Ozone disinfection:
Results: It is feasible. Sterilization is more thorough, but pay attention to the harm.
Ozone disinfection is relatively simple to operate. Put the rubber hose connected with Audi A3 special sterilizer into the carriage, turn on the special sterilizer and the air switch in the car, and use the air circulation of the air switch to send the high-concentration ozone generated by the special sterilizer to every corner of the car in just a few minutes. The fly in the ointment is that there will be a little ozone smell in the compartment after disinfection, but as long as the window is opened for a while, the ozone will automatically decompose into colorless and odorless gas and evaporate. If the owner often uses the vehicle, disinfect it once a month. The price of ozone generator ranges from 2000 yuan to 10000 yuan, and many automobile beauty service shops provide ozone disinfection services, with charges ranging from tens to hundreds of yuan. Because ozone has some fishy smell, it has certain irritation and strong oxidation. Although it can be sterilized, it will lead to premature aging of interior decoration materials. Reminder: this is effective for eliminating odor, but it is ineffective for eliminating formaldehyde.
6. Tea deodorization:
Results: it is feasible, but the effect is not great.
Tea stems are used as deodorants. The new Audi A3 always smells bad. Tea stems can be used to remove odors. Put the tea stems in a cloth bag and put them in the corner of the car. Change it in a few days. In a few days, you will feel that the car tastes much better, natural, environmentally friendly and healthy. In addition, add some petals of jasmine and lily.
7, activated carbon deodorization:
Results: It is feasible, with low cost, but the effect is average.
Automobile deodorizing activated carbon bag is a product specially designed for automobile deodorization, aiming at many health hazards caused by air pollution in automobile garages on the market. Because the structure of activated carbon is characterized by many pores and strong adsorption, it can not only adsorb formaldehyde, but also adsorb other polluting gases, and will not cause secondary pollution. Activated carbon should be replaced after it is saturated, about once every three months. The price of pollen filter and activated carbon adsorber ranges from ten yuan to tens of yuan.
Reminder: This is also one of the best methods. The cost is not big, but the effect is really good. After the activated carbon is used in the car for a period of time, it can be taken out and reused, and then exposed to the sun for reuse.
8, perfume deodorization:
Results: it is not feasible and easy to have negative effects.
Perfume, perfume, sachet or air freshener can remove odor, but can only cover it up, but not eliminate it. Some inferior products can also cause allergies, dizziness, nausea and other symptoms. These methods will only make people more numb and harmful.
Summary: There are many ways to deodorize new cars. When you buy a new car, you must open the window less. This habit should be maintained for at least half a year. Don't expect perfume, activated carbon, etc. Although the smell feels much better, the actual adsorption effect is very limited. If the owner doesn't know how to deodorize the new car, he can give it to a professional in a 4S shop.
