Safety hazards: As temperatures gradually rise, this may pose a fire hazard. The dashboard of a car can reach temperatures as high as 80 to 90°C under the scorching sun. If an alcohol bottle deforms and alcohol leaks out, forming vapor, it can create an extreme fire risk, potentially leading to spontaneous combustion or even explosion in severe cases. Other items that should not be left in the car: Mineral water bottles should not be left: At noon, the temperature inside a closed car can reach nearly 70°C. Sunlight entering through the windows can focus through the edges of the water bottle, raising the temperature to 120°C, which can easily ignite items like anti-slip mats inside the car. Electronic devices should not be left: High summer temperatures and the lack of ventilation in the car cabin can cause power banks, batteries, and other electronic devices left in the car for extended periods to swell or even explode. Lighters: Ordinary lighters mainly contain liquid butane, which is flammable and explosive. High concentrations of butane can explode at just 20°C under normal conditions. Once the ambient temperature exceeds 55°C, the lighter's volume will expand. Carbonated drinks: During summer, car interiors can become extremely hot, especially when the car is not moving. Sunlight refracted through the windshield rapidly increases the cabin temperature. Carbonated drinks already contain gas, and even slight shaking can cause the bottle to expand. Combined with thermal expansion, this makes them more prone to bursting.

I've been driving for over 20 years, and keeping alcohol in the car during summer does pose safety hazards. When parked outdoors, temperatures often soar to 50-60°C, causing alcohol bottles to expand from heat or even burst. Leaked liquid evaporates into gas, which can ignite upon encountering any spark like from a lighter or static electricity. I recall a similar accident reported last year where a car was completely burned, resulting in significant losses. Additionally, poorly sealed bottles allow alcohol to evaporate quickly, degrading air quality inside the car with a pungent smell that may cause dizziness. It's advisable not to store alcohol long-term. If necessary, choose a shaded spot and wrap it in double plastic bags, avoiding direct sunlight on the dashboard. Carrying alcohol wipes as an alternative is more convenient and safer for daily use.

As a health-conscious office worker, I believe we should be careful about keeping alcohol in the car during summer. When the car temperature rises, alcohol evaporates rapidly, and prolonged exposure to the resulting fumes in the enclosed space of a car with closed windows may affect the respiratory system. High concentrations can easily cause coughing or dizziness, posing greater risks if there are children or pets in the car. Additionally, if alcohol liquid leaks, it can corrode seats or electronic devices, making cleanup difficult and costly. I've found that using alcohol-soaked paper towels for one-time use is more reliable, or purchasing non-volatile disinfectant sprays can be both convenient and avoid potential hazards. Remember to park in a shaded area to prevent accelerated evaporation from direct sunlight.

As a car enthusiast with extensive experience in vehicle modification, I can tell you that keeping alcohol in your car may damage the interior. In the high temperatures of summer, alcohol evaporates quickly and can corrode plastic and leather surfaces, causing the car to age and discolor. Worse yet, if it seeps into wires or switches, it may cause short circuits and affect the car's functionality. It's advisable to avoid storing such liquids long-term. If you must keep it, use a sealed container to ensure no spills and regularly check that the cap isn't loose. For actual disinfection needs, carry a small portable bottle for temporary use.
