Is In-Car Cooling Spray Safe?
2 Answers
In-car cooling spray has a certain level of safety, but it also carries some potential hazards. Here is relevant information: 1. Glass breakage: It may cause glass to crack. After being exposed to intense sunlight, the surface temperature of glass becomes extremely high. When this rapid-cooling spray is applied to the surface, it can lead to varying degrees of breakage. 2. Risk of explosion: The main components of cooling spray are chemicals, which require protection. It should be kept away from direct sunlight and temperatures above 50°C to prevent explosions. 3. Overview: The main ingredients of car cooling spray include dry ice (solid carbon dioxide), some natural fragrances, and softening agents. The cooling spray works by vaporizing after application, absorbing heat through vaporization, and thereby removing heat from the surfaces of surrounding objects, providing a certain cooling effect. However, this effect is localized and cannot achieve a comprehensive cooling effect.
I've been driving for 20 years and have tried several cooling sprays. To be honest, they are convenient but require caution regarding safety. Last summer, I used a bottle to spray the car seats, and the interior temperature was so high that the spray mist nearly ignited the seat covers, which gave me a scare. After researching, I learned that the propellants in such sprays, like propane, have low ignition points, making them prone to catching fire when used in areas exposed to direct sunlight or on hot surfaces. Additionally, if the ingredients are chemical coolants, inhaling too much can be harmful to the respiratory system. For safety, it's best to buy reputable brands like 3M or Turtle Wax and check the product description for flame-retardant labels. When using, first open the windows for ventilation and avoid spraying directly at people or electronics. A better, longer-lasting, and safer approach is to turn the air conditioning to high or use a sunshade. Regularly check that the spray bottle isn't left in high-temperature areas like the dashboard.
