Will sunscreen spray explode if placed in the car in summer? These things should never be placed in the car in summer.

As soon as summer comes, I believe everyone will start preparing for their own sun protection. Nowadays, there are many sun protection methods and products for us to choose from, and the most popular one is definitely sunscreen spray. But will sunscreen spray explode if left in the car in summer?

Will sunscreen spray explode if left in the car in summer?

Might explode. If you leave it in the car for a short period of time and it doesn't come into contact with open flames, it may be fine. But it is very dangerous if left for a long time. The reason why canned sprays such as sunscreen spray, hairspray, shaving foam, insecticide, etc. can spray the liquid in the can is because the pressure in the can is very high, and the items in the spray are themselves flammable. If it is exposed to the sun in the car, it may explode.

These things should never be left in the car in summer

1. Canned carbonated drinks. Carbonated drinks are very likely to explode when exposed to high temperatures and collisions, so never leave sealed canned drinks in a car exposed to the sun. If you are not careful, the seats, door and window handles of your car will be covered with sticky liquid, which may take you an entire afternoon to clean.

3. Lighter. The main ingredient of ordinary lighters is liquid butane, which is flammable and explosive. High concentration of butane will explode at room temperature, 20 degrees Celsius. Once the ambient temperature of the lighter exceeds 55 degrees Celsius, its volume will expand. The outdoor temperature is above 30 degrees Celsius, and after being exposed to the sun, the temperature inside the car can reach 60 or 70 degrees Celsius at any time. This is very dangerous in summer. It will explode if you are not careful, with disastrous consequences.

4. Various spray cans. In summer, many people like to use sprays to relieve the heat, such as hydrating spray, cooling spray, sunscreen and so on. But these sprays, like carbonated beverage cans, are very prone to explosion at high temperatures. If it is exposed to the sun inside the car, its power will be very strong. If you smoke in the car at this time, the gas will meet the open flame and further cause the fire.

5. Glasses. Many times, we just leave our glasses in the car, but under direct sunlight and exposure, the plastic frames of the glasses are very likely to twist and deform. It may not be visible in the short term, but it will cause problems in the long run. What’s more important to note is that if your glasses have metal frames and have just been exposed to the sun, you must not put them on immediately, as you are likely to get burned! In addition, reading glasses are convex lenses, which tend to gather light together. If they are exposed to direct sunlight and the light is concentrated for a long time, the temperature of the focal point can easily rise rapidly.

6. Sunscreen. One of the must-have products for going out in summer is sunscreen, but do you know? In a high temperature environment, the sunscreen ingredients in sunscreen will also deteriorate, resulting in a significant decrease in the sun protection effect. In addition, sunscreen may explode if the environment around it is too hot.

7. Perfume. To keep the air fresh, many people put liquid perfume in their cars. However, when perfume evaporates, it will produce flammable gas, and its critical explosion point is 49 degrees Celsius. If exposed to the summer sun for just 15 minutes, the temperature inside the car will rise to 65 degrees, which can easily cause an explosion.

8. Mobile power supply and battery. Nowadays, when going out, everyone will bring some mobile power supplies, such as power banks. These items are marked in the instruction manual as not to be used in high temperatures and are very likely to explode if exposed to the sun in a car. Furthermore, there are many substandard mobile power supplies (also known as "power banks") in the domestic market. Some unscrupulous merchants use fake or refurbished batteries, which are more likely to cause explosions. If the acid in the battery leaks, it will cause irritation to the skin, respiratory system and eyes.

How to cool your car in summer

1. Cold air inhalation method. First, we need to roll down the passenger window, and then open and close the driver's door several times. This is to quickly push the hot air out of the car and draw in the cool air outside the car. After a few cycles, the temperature inside the car will naturally drop.

2. Make your own cooling spray. As we all know, alcohol is easy to evaporate and takes away a lot of heat when evaporating. All we need is a spray bottle, a bottle of medical alcohol, and a bottle of purified water. Pour alcohol and water into a spray bottle in a ratio of 1:9 to get a cheap and effective cooling spray!

3. Use skylights. If your car happens to have a sunroof, you can open it and then turn on the air conditioner. At this time, an air convection channel will be formed in the car, which can quickly expel the heat in the car.

4. Sun visor. The sun visor is a great way to protect your car from the sun, so every time you get out of the car, even for a short while, remember to put up the sun visor!

5. Instrument panel cover insulation pad. The area in front of the dashboard is most vulnerable to direct sunlight, but covering them with an insulating pad can effectively prevent the temperature inside the car from rising and protect this part of the leather from cracking or fading.

6. Cover the steering wheel with a towel. Cover the steering wheel with a towel or something else so you don’t have to worry about burning your hands while driving!

7. Try to park indoors or in a cool place. Try to park your car in a sheltered place, such as next to a wall or under a tree, so that it won't be hot when you get back in. Of course, it would be great if you can find indoor parking.

8. Spread the blanket flat on the seat. If the seats in your car are made of materials like leather, then high temperatures will definitely damage them. At this time, you just need to cover the seat with a blanket to successfully isolate the sunlight. Especially for baby seats, you don’t have to worry about your child getting prickly heat after covering them!

9. Solar fan. The fan can speed up the ventilation circulation and make the air in the car slightly cooler. At the same time, it can be charged by solar energy, so there is no need to buy batteries!
