How to Remove Window Paint from Car Body

Test the denatured alcohol in an inconspicuous area. Denatured alcohol can damage some types of paint, so it’s important to test it in an inconspicuous area first.
Apply denatured alcohol to a soft cloth. Do not apply the alcohol directly to the car’s paint.
Gently rub the cloth over the window paint. Use a circular motion and apply light pressure.
Rinse the area with clean water. Use a clean, soft cloth to rinse away the alcohol and any remaining window paint.
Dry the area with a clean cloth.
Apply automotive wax to the area. This will help to protect the car’s paint from future damage.

If the window paint is stubborn, you may need to use a stronger solvent, such as acetone. However, acetone can damage car paint, so it’s important to use it only as a last resort.
Be careful not to rub too hard when removing the window paint. This could damage the car’s paint.
Always rinse the area thoroughly with clean water after using any type of solvent.
To prevent window paint from getting on your car in the future, park your car in a shaded area or cover the windows with a tarp.
