A cracked windshield may cause glares that can adversely affect your driving. Windshield cracks not only make your vehicle look bad, but they can spread and lead to larger cracks and eventually complete windshield replacement. You can easily repair your cracked windshield at home with a few supplies.
Pour 1/4 cup of water to the mixing bowl. Then add a 1/2 teaspoon each of salt, bug repellent and rubbing alcohol. Stir the contents of the bowl until the salt is dissolved.
Dip the rag in the solution and rub it into the crack. Keep dipping the rag in the solution and rubbing it into the crack until all the solution is gone.
Allow the windshield to dry for several hours. The rubbing alcohol and bug spray chemically react together to soften the plastic cover originally manufactured over the glass windshield. The salt then acts as a filler in the rubbing alcohol and bug spray mix. Once it drys it looks like there was never a crack in the window.
