Alcohol can be sprayed inside the car for disinfection. However, the following points should be noted: 1. Wipe dry immediately: Alcohol is a flammable and explosive product. If alcohol is sprayed for disinfection, it should be wiped dry immediately. Keep the car windows open in a well-ventilated environment, and try to spray on the surface of objects, avoiding hidden or hard-to-reach areas inside the car. 2. Ventilation: After disinfecting the car interior, do not smoke inside the car or close the windows, as the rising temperature can reach the ignition point of alcohol, which may easily lead to explosions or fires.

Using alcohol to disinfect the car is indeed a common method, as it effectively kills bacteria and viruses—70% ethanol concentration can do the job. However, many materials in the car can't withstand alcohol. Plastic panels may become brittle and crack, leather seats could fade or age, and even the dashboard screen might get scratched. It's recommended not to use high-concentration pure alcohol; instead, dilute it with water to around 70%, lightly wipe surfaces with a damp cloth, and avoid forcing it into gaps. Ventilation is crucial—open windows to air out the smell. For regular disinfection, prioritize commercial car-specific sprays with gentler ingredients. Remember, alcohol is flammable, so smoking or using lighters in the car poses significant risks—safety always comes first.

I've seen many car owners spraying alcohol inside their cars for convenience, but this simple method hides significant risks. Car interiors, like fabric seats, can absorb alcohol and leave stains, turning yellow over time; plastic parts may age faster, causing items like door handles or steering wheel covers to crack. I once tried wiping the dashboard with 70% isopropyl alcohol and found white marks a few days later—nearly cried my eyes out. Later, I switched to disinfectant wipes from the supermarket, which are much more convenient. Don't do it too often; once or twice a month is enough, focusing on frequently touched areas like door handles and seatbelt buckles. Ventilate for half an hour before turning on the AC to avoid health risks from residue.

Alcohol disinfection for car interiors has both pros and cons. The advantages are its affordability and accessibility, effectively killing most germs. The downside is its potential harm to interiors: alcohol's strong corrosive nature may cause leather seats to deform or crack, plastic trims to become brittle and age, and window glass to fog up. There are many alternatives, such as specialized disinfectants from car detailing shops, or diluted household white vinegar mixed with baking soda, which are equally effective and eco-friendly. Always wear gloves when applying, avoid direct spraying, and gently wipe with a damp cloth instead.

As a seasoned road-tripper, I often use alcohol to disinfect my car, especially after long drives to kill bacteria. But I learned a hard lesson: once I sprayed too much alcohol, and the plastic around the AC vents turned white—I regretted it deeply. Later, I got smarter: using 70% alcohol in small sprays, wiping thoroughly with a damp cloth, and avoiding leather and sensitive screen areas. Ventilation is key—open the windows to air out the smell. Commercial disinfectant sprays are even better, with gentle formulas that protect the interior. Control the frequency; don’t overdo it daily. After disinfecting, check if surfaces are dry to avoid leaving marks.
