Can alcohol disinfectant be sprayed inside the car?
3 Answers
Alcohol disinfectant can be used inside the car. Alcohol has disinfecting and sterilizing properties, but it is recommended to use a wiping method instead of direct spraying. Before using 75% alcohol for disinfection, the car should be turned off and kept in a non-operational state. Ensure proper ventilation in the car and avoid contact with open flames to prevent explosions. Precautions for using alcohol to disinfect the car include: 1. Alcohol is a flammable and explosive product, so any sprayed areas should be wiped dry immediately after disinfection; 2. Keep the car in a well-ventilated area with windows open, and try to spray only on object surfaces, avoiding hidden or hard-to-reach areas inside the car; 3. After disinfecting the car, avoid smoking inside or closing the windows, as rising temperatures could reach the ignition point of alcohol, leading to explosions or fires.
I think it's best not to directly spray alcohol disinfectant in the car. Although it can disinfect, it's quite dangerous. Alcohol is highly flammable, especially in summer when the car gets hot enough to fry an egg—it could easily catch fire. Moreover, the confined space inside the car causes alcohol to evaporate quickly, potentially forming an explosive mixture. If you light a flame or start the car at this point, a spark could lead to disaster. Additionally, it's not friendly to car interiors—spraying it on leather seats can cause them to harden and crack, plastic parts may fade, and if it gets on the infotainment screen, it could short-circuit. If you really need to disinfect, it's better to use alcohol wipes to clean specific areas like door handles or the steering wheel. Avoid using spray-type disinfectants in the car. Safety first—keeping a bottle of hand sanitizer in the car is a more reliable option.
If you cherish your car like your life, never spray alcohol on the interior. I’m someone who treasures possessions dearly, and I’ve seen the tragic sight of a friend’s dashboard ruined by alcohol sprays. Leather seats sprayed with alcohol can dry out and crack like old tree bark, while synthetic leather may even bubble up. As for the fabric on the ceiling, alcohol can leave permanent white stains, ugly and hard to fix. Plastic parts are even more fragile—especially those faux carbon fiber trim panels, which can fade and turn white after just a few sprays. Why take the risk for disinfection? Use a neutral, car-specific cleaner sprayed onto a soft cloth for gentle wiping; it removes dirt and kills germs. Regularly opening windows for ventilation works far better than spraying alcohol, keeping your car clean and extending its lifespan.
