If ice is left on a car windshield, it can become hard to remove. It is best to prepare your windshield so that the ice does not stick to it in the first place. You can purchase a product such as Rain-X from a store or use products that are commonly found in most homes.
Pour vinegar all over your windshield the night before a frost or a snowstorm. The vinegar will keep the ice and snow from sticking to the windshield so that it can be easily removed.
Spray your windshield wipers with nonstick cooking spray. This will keep ice and snow from sticking to the wipers so that you can use them to easily remove the ice and snow from the windshield.
Pour rubbing alcohol on any patches of ice that have not easily come off the windshield. The alcohol will melt the ice and snow.
