What should be avoided when removing stickers from a car window?

When removing stickers from a car window, avoiding using blades or sharp tools that may scratch the glass is important. Tools such as knives or razor blades can cause scratches. It is also crucial not to use excessively hot heat sources, like an open flame or a very powerful hairdryer, to prevent thermal damage to the glass. Additionally, caution should be exercised when using chemical agents that may be harmful to the surface of the glass or the car’s paintwork.
