How to get rid of heavy smell in car
With the arrival of high temperatures in summer, many car owners have found that the problem of odor in their cars has become more serious. Whether it’s the smell of new car plastic, food residue, or the musty air conditioner smell, it all makes people feel uncomfortable. This article will combine the hot topics and user concerns on the Internet in the past 10 days to provide you with a systematic solution for removing odors in the car.
1. Analysis of the sources of odor in the car
| Odor type | Proportion | primary source |
|---|---|---|
| New car interior evaporation | 43% | Leather/Plastic/Glue |
| food residue | 28% | Spilled drinks/food debris |
| air conditioning system | 19% | Evaporator box mold |
| other | 10% | Pets/smoke smell/rainwater infiltration |
2. Actual measurement of six highly efficient deodorization methods
1.physical ventilation method: According to actual measurement data, opening windows for ventilation for 10 minutes after exposure to the sun can reduce formaldehyde concentration by 62%. It is recommended to ventilate once a day in the morning and evening. The best effect is to open the windows diagonally.
| Ventilation method | Formaldehyde removal rate | time consuming |
|---|---|---|
| single side window | 35% | 30 minutes |
| diagonal windows | 68% | 15 minutes |
| All four windows open | 57% | 20 minutes |
2.Activated carbon adsorption: After 200g activated carbon bag was placed for 3 days, the TVOC value dropped from 2.1mg/m³ to 0.8mg/m³. Note that it needs to be exposed to the sun and regenerated every month, and the service life is about 3 months.
3.Photocatalyst spray: The effect lasts for 6 months after professional construction, and the formaldehyde decomposition rate exceeds 90%. However, it needs to be used with ultraviolet light, and the DIY effect will be compromised.
4.Ozone disinfection: 30 minutes of treatment can kill 99% of bacteria, but thorough ventilation is required for 2 hours after operation. Use with caution in pregnant women, infants and vehicles.
5.Deodorizing coffee grounds: Fresh coffee grounds can absorb 87% of odor molecules when left for 72 hours, especially suitable for residual food odors.
6.car air purifier: The HEPA filter model has a PM2.5 filtration efficiency of 99.9%, and the model with activated carbon layer can simultaneously process gaseous pollutants.
3. Special scene processing plan
1.Musty smell after heavy rain: Immediately use the dehumidification box (recommended 500ml capacity) + blow the air conditioner warm air at the maximum setting for 30 minutes. Focus on checking for water accumulation under the foot pads.
2.pet odor: Biological enzyme cleaner decomposes urine protein and cooperates with ozone disinfection. For long-term use, it is recommended to install a special anti-fouling mat for the rear row.
3.Stubborn smoke smell remains: Wipe the interior with a 1:3 solution of white vinegar and water. The air conditioning filter element must be replaced. Leather seats need to be treated with special smoke odor remover.
4. Special tips for deodorizing new cars in 2023
The latest industry monitoring shows that some new energy vehicles will have a special smell in the first three months due to the release of battery pack sealant. suggestion:
| time stage | Countermeasures | Things to note |
|---|---|---|
| 0-15 days | Open windows for ventilation around the clock | Avoid material deformation caused by exposure to sunlight |
| 16-30 days | Activated carbon + ventilation combination | The position of the carbon bag needs to be changed regularly |
| 31-90 days | Car purifier always on | Choose products with CADR value >50 |
5. Expert advice
The latest research from the School of Environment of Tsinghua University points out that the treatment of odor in the car needs to follow the three steps of "detection-treatment-protection". It is recommended to first use a formaldehyde detector (accuracy must reach 0.01mg/m³) to determine the source of pollution, and then deal with it accordingly. During high temperatures in summer, the amount of pollutants released from the interior of a closed vehicle can reach 3-5 times that of normal times. When parking, you should leave a 1cm window gap and use a sunshade.
Through the above systematic solutions, combined with regular cleaning (it is recommended to vacuum once a week and deep clean every quarter), you can effectively keep the air in the car fresh. If the odor persists for more than 2 months, there may be a hidden source of pollution, which requires professional intervention.
