This will be a very short and straightforward post. Simply put, Avoid washing your car when it’s been sitting in the sun and is hot, YOUR GLASS CAN BREAK when it comes in contact with the water. This is also possible to occur if the car is frosted and you pour hot water to the glass.
We all love that fresh, clean look of a freshly washed car, but there’s more to consider when choosing the right time and place to wash your vehicle. If your car is sitting in the sun and exposed to high temperatures, it’s not just the paintwork and surface that can suffer—your glass can be at risk, too. Here’s why you should avoid washing your car when it’s sitting in the sun and heat.
Glass Can Crack or Shatter When it Comes in Touch With Opposite Temperature Water
One of the most serious risks of washing your car when it’s sitting in the sun is the potential for your glass to crack or shatter. When the sun heats up your car’s windows, it can cause them to expand. If you apply cold water or a cool cleaning solution to a hot surface, or hot water to a frosted glass, the sudden temperature change can cause the glass to contract rapidly. This can lead to stress fractures, and in extreme cases, the glass could even crack or shatter. This is especially dangerous for your windshield, as a crack could obstruct your view while driving and require costly repairs or replacement.
