Are you a car enthusiast who enjoys washing your vehicle in the summer heat? If so, you need to be cautious. In hot areas, car glass can crack or even explode during the washing process. This article will explore the reasons behind this phenomenon and provide tips to prevent it.

Under high temperatures, car bodies and glass can become extremely hot. If you wash them with cold water immediately, the overheated glass will undergo rapid expansion and contraction, leading to cracks. Nowadays, most car windows are covered with film. When exposed to cold water at high temperatures, the shrinkage ratio of the film differs from that of the glass, which can also cause glass cracks.

Moreover, if the glass has small cracks or pits due to impact, exposure to cold water at high temperatures can enlarge these cracks from the weak points. After investigation, the key factor is the combination of high temperatures and exposure to cold water. Additionally, when the temperature of car paint, rubber parts, and brake pads is high, sudden exposure to cold water can accelerate their aging.

To avoid these issues, it’s best to choose manual drying or a fully automatic car wash machine with a blow-drying function when washing your car in hot weather.

Here are some tips for washing your car in summer:

– Avoid washing your car at noon if it has been driven long distances during the day. Instead, park it in a cool and shady place to cool down naturally before washing.

– It’s best to wash your car in the morning and evening during hot summer days, and avoid washing under the scorching sun at noon.

– Set up a shading shed or net at the entrance of the fully automatic car wash machine. This allows vehicles waiting for cleaning to enter a cooling mode in advance, reducing the temperature difference between the car body and the cleaning water.

– Before entering the car wash machine, wet the car glass with water. The water used to spray the car glass can be water stored in a tank exposed to the sun. This way, the water temperature can be around 10-25 degrees Celsius, softening and pre-cooling the glass, and reducing the impact of temperature differences on the car glass.

Additionally, when washing your car in hot weather, it’s best to choose manual drying or a fully automatic car wash machine with a blow-drying function to remove water droplets from the car’s surface. Residual water droplets can act as convex lenses under strong light, causing local overheating and uneven paint color.

By following these tips, you can protect your car’s glass and paint from damage during summer washing.
