Cleaning car windows can be frustrating, especially if you’ve never done it before. Due to the stubborn nature of the grime buildup on car windshields, people who have been doing it for years still use a towel when they’re finished with most of the glass. Cleaning the windows is often overlooked during a car wash, getting bare minimum attention to remove bugs.

Car owners want to know how car windows get so dirty in the first place? How do you clean it? How dirty can they get before you need to have them professionally cleaned? How much does that cost, and is it worth it? We’ll answer all of these questions in this article.

How Do Car Windows Become So Dirty?

How to clean inside car windows

There are many reasons why car windows become so dirty.

  • Exposure to elements: One of the main reasons is that car windows are constantly exposed to the elements such as wind, rain, and snow. These elements can cause the dirt and debris on the roads to stick to the windows, making them very dirty.
  • Ventilation System: Another reason why car windows get so dirty is because of the car’s ventilation system. When the car’s ventilation system is turned on, it causes the air to flow over the windows. This air can pick up dirt and debris from the roads and deposit it on the windows.
  • Through Peoples: Another reason car windows get dirty is the people inside the car. People can transfer dirt and debris to the windows simply by touching them. Furthermore, when people breathe, they can expel saliva and other particles that stick to the windows.
  • Sun UV rays: Finally, car windows can become dirty over time simply from normal wear and tear. The sun’s UV rays can cause the windows to fade and crack, which can then lead to the accumulation of dirt and debris.
