Can Alcohol Be Sprayed on Cars for Disinfection?

[AaliyahDella]

Alcohol can be sprayed on cars for disinfection. Alcohol has disinfecting and sterilizing properties, but using it for wiping instead of direct spraying is preferable. Before disinfecting with 75% alcohol, the car should be turned off and kept in a non-operational state while ensuring proper ventilation. Avoid contact with open flames to prevent explosions. Here are some relevant details: 1. To achieve disinfecting and sterilizing effects, 75% medical-grade alcohol should be used. Lower concentrations may not be effective. 2. Alcohol molecules have strong permeability, allowing them to penetrate bacterial membranes, enter the bacteria's interior, coagulate the proteins essential for bacterial life, and kill the bacteria. When alcohol concentration exceeds 70%, its evaporation increases the flammable gas content in the car's air. Even a small spark could trigger an explosion. 3. Additionally, since car interiors often feature leather and plastic materials, high-concentration alcohol may corrode these surfaces. Therefore, after disinfecting with alcohol, ensure frequent ventilation and wait for it to evaporate before starting the car.
