How to quickly deodorize a new car? Analysis of hot topics on the Internet in 10 days
Buying a new car is exciting, but the smell inside your new car can be a headache. Formaldehyde, benzene and other harmful substances may be lurking in it, affecting health. Recently, the discussion on "new car deodorization" has soared across the Internet. This article will combine hot topics and data in the past 10 days to provide you with scientific and effective solutions.
1. Sources and hazards of new car odor
New car odors mainly come from volatile organic compounds (VOCs) released from interior materials, adhesives, plastic parts, etc. The following are common hazardous substances and their hazards:
| Hazardous substances | primary source | health hazards |
|---|---|---|
| Formaldehyde | Seats, carpets, glue | Irritates the respiratory tract and may cause cancer |
| Benzene series | Plastic parts, paint | Damage the nervous system and cause dizziness |
| TVOC | Mixed release of multiple materials | Long-term exposure leads to reduced immunity |
2. Ranking of the most popular deodorizing methods on the Internet
Based on the discussion on social platforms (Weibo, Xiaohongshu, Zhihu, etc.) in the past 10 days, the following most popular deodorizing methods have been sorted out:
| method | support rate | Advantages and Disadvantages |
|---|---|---|
| Exposure + ventilation | 85% | Low cost but time consuming |
| Activated carbon adsorption | 72% | Needs to be replaced regularly, the effect is mild |
| car air purifier | 68% | Efficient but more expensive |
| Photocatalyst spray | 55% | Professional operation is required to decompose formaldehyde |
| Fruit peel (grapefruit, pineapple) | 30% | Masks odors instead of actually removing them |
3. Scientific and efficient deodorization steps
Based on expert advice and actual user testing, the following phased operations are recommended:
1. Early stage (1-3 days):-High temperature exposure:Choose a sunny day, park your car in the sun, and open the windows/sunroof to speed up evaporation. -Ventilation and convection:Open the external circulation when driving and leave gaps for ventilation when parking.
2. Mid-term (3-7 days):-Physical adsorption:Place activated carbon packs (1 pack per 50km²) and reuse after 48 hours of exposure. -Chemical breakdown:Use formaldehyde remover to spray seats, dashboards, etc.
3. Long-term maintenance:-Regular cleaning:Wipe the interior with a damp cloth to reduce dust and odors. -Air testing:One month after purchasing the car, a detector can be used to confirm the formaldehyde concentration (≤0.08mg/m³ is considered safe).
4. Guide to avoiding pitfalls: These methods are not recommended!
According to the experimental data of the quality inspection agency, the following methods have limited effectiveness or risks:
| method | question |
|---|---|
| Perfume/Aromatherapy | Masking the smell may cause secondary pollution |
| Vinegar fumigation | Corrodes the interior, the effect lasts only a few hours |
| Ozone disinfection | Overuse can damage the respiratory tract |
5. Actual test cases of car owners
Xiaohongshu user @爱车者Zhi shared: “After 3 days of exposure to the sun + activated carbon, the formaldehyde value dropped from 0.15 to 0.05, but remember to replace the carbon pack every two weeks!”
Summary:New car deodorization requires a combination of physical adsorption and chemical decomposition, and significant improvement can be achieved after 2-4 weeks. If the odor persists for more than 1 month, it is recommended to contact the 4S store to check the quality of the interior materials.
