The only home remedy for repairing a small windshield crack or chip is to use a windshield crack repair kit, which can be purchased at an auto parts store or any large discount store. If not repaired in a timely manner, the windshield crack will likely worsen.
Although a windshield crack may be small and not in the driver’s line of sight, it is likely to turn into a longer, thicker crack overtime, and eventually, a new windshield might be necessary. Before using a crack repair kit, the windshield must be clean and completely dry. The windshield should also be kept at close to room temperature.
