Can You Wash a Car After It's Been Exposed to the Sun?
1 Answers
It is not advisable to wash a car after it has been exposed to the sun. During summer, when a vehicle is driven outside and subjected to high temperatures, the surface temperature of the car body becomes very high. Washing the car with cold water at this time can cause significant damage to the paint surface, potentially leading to cracking or bubbling of the paint. Additionally, the sudden temperature difference can affect the internal machinery of the car, possibly causing cracks in metal components, which may impair the vehicle's normal operation. Here are some precautions for car washing: 1. Avoid washing the car under direct sunlight: Do not wash the car in the sun or leave it in the sun after washing. Water droplets left on the car act like convex lenses, focusing sunlight onto the paint and causing damage. Moreover, uneven evaporation of water can lead to uneven heating of the car body, with localized areas becoming excessively hot. Over time, this can damage the paint, resulting in a dull appearance. 2. Do not wash the car too frequently: Excessive washing is harmful to the car's paint. For cars that have been waxed or coated, frequent washing can wear away the protective layer, accelerating paint aging without protection. It is recommended to wash the car once every ten days or half a month, as washing too often is not only harmful but also a waste of money.
