A scratch on the window of a vehicle can be a driving hazard. It is possible to remedy with a few household items.
Rinse the scratched area with warm water to remove all accumulated debris, dirt and dust from the window.
Mix the toothpaste and baking soda in a bowl until it becomes a thick, pasty substance.
Apply the paste directly on the scratch, and allow it to sit for several minutes. Using a nonabrasive hand towel, run the paste compound into the crevices of the scratch. Because this paste solution is abrasive, it helps smooth out the scratches.
Rinse off the paste debris from the scratched area with warm water. The scratch should no longer be visible.
If the scratch on your car's window is deep, you should consult an automotive professional, as this method is to be used for superficial scratches only.
