Can You Wash a Car When It's Very Hot from the Sun?
1 Answers
You should not wash a car when it's very hot from the sun. Here are the relevant explanations: 1. High temperature: The reason why it is not recommended to wash the car immediately after exposure to the sun is that the temperature of the front windshield is high at this time. Once it comes into contact with cold water, it is easy to crack due to thermal expansion and contraction. In addition, the car paint should not be directly rinsed with cold water after exposure to the sun. The reason is still the principle of thermal expansion and contraction. If the car paint is directly rinsed with cold water after exposure to the sun, it is easy to cause phenomena such as paint cracking. 2. Aging of the paint protective layer: After the car has been exposed to the sun, it can also be moved to a shady place for about half an hour to allow the temperature inside the car to drop. You can also touch the body or glass with your hand to feel the temperature, with a temperature close to body temperature being the best. Do not wash the car too frequently. Washing the car too frequently will cause the protective layer on the surface of the paint to be lost. Without the protective layer, the aging of the paint will be accelerated.
