Some commercial products repel water from your windshield while driving in the rain. This helps greatly with visibility, and also makes it easier to remove the ice that forms on the windshield. While not expensive, if you want to make a homemade windshield water repellent, you can do it with a handful of ingredients. You can make a simple solution with water and alcohol, or a repellent that comes closer to the ingredients of a windshield water repellent purchased in a store.
