1. Plastic Water Bottles

Plastic drinking water bottles, you must check what type of plastic the bottle is and how much heat it can withstand. Most are PET, PETE, made from polyethylene terephthalate plastic. It is plastic number 1 out of 7 types of recycled plastics. The bottles are clear, strong, durable, lightweight, not easily broken, and prevent gas penetration well, so they are used to contain drinking water. They can withstand high temperatures up to 60-95°C. But if a plastic water bottle contains water, when exposed to sunlight, the water bottle acts like a lens, converting into heat energy, which can cause the car to catch fire. Besides plastic water bottles, glasses can also cause fires.

2. Valuables

Do not leave cash, brand-name bags, especially electronic devices such as laptops and mobile phones, as this will cause them to deteriorate faster than usual, leading to internal damage. It also helps prevent theft, such as smashed windows, ambushes at night, or when parking in isolated areas.

3. Power Banks

When parking a car in direct sunlight, the rising temperature and extreme heat can cause the battery to degrade, potentially leading to explosions and fires.

4. Medicines

The temperature inside a car can rise significantly on very hot days, especially in Thailand's climate. This can cause medicines or medical supplies to degrade, expire faster than they should, and potentially become ineffective for treatment.

5. Food

Most foods, especially fresh items, may not withstand hot weather and can spoil easily. This also includes eating food in the car, which can lead to food scraps falling inside the car and causing persistent bad odors that are difficult to eliminate. It may also attract various animals into the car, such as mice, snakes, and insects. If these are dangerous animals, they could pose a threat to ourselves and passengers.

The items listed here, if left in the car, may pose a risk of damage to your car and your property. They should not be kept in the car.
