Hiding a crack in a windshield

A windshield cracked can produce glare that can affect your driving. The cracks in the windshield not only make your vehicle look bad, but can be extended and lead to large cracks and eventually to a complete windshield replacement. You can easily repair your cracked windshield in your home with some instruments.


  1. Pour 1/4 cup water into the mixing bowl, then add 1/2 teaspoon salt, 1/2 and 1/2 insect repellent isopropyl alcohol. Stir the contents of the bowl until the salt has dissolved.
  2. Dip the cloth in the solution and rub it against the crack. Still wetting the cloth in the solution and rubbing it against the crack until the solution runs out.
  3. Allow the windscreen to dry for several hours. Isopropyl alcohol and insect repellent react together and soften the plastic cover that is above the windshield glass. Then the salt acts as filler in the mixture of isopropyl alcohol, and insect repellent. Once dry, it is as if there had never been a crack in the glass.
