Distilled Water
Distilled water is the purest form of water available. It has undergone a process called distillation, which involves boiling water and then condensing the steam back into liquid form. This process removes all impurities, including minerals, salts, and organic matter. Distilled water is the best choice for windshield washer fluid because it will not leave any residue on your windshield or damage your washer fluid system. However, distilled water can be expensive, so it is not always the most practical choice.
Deionized Water
Deionized water is another good choice for windshield washer fluid. It has been treated with a chemical process that removes all ions, including minerals, salts, and organic matter. Deionized water is not as pure as distilled water, but it is still a good choice for windshield washer fluid because it will not leave any residue on your windshield or damage your washer fluid system. Deionized water is also less expensive than distilled water, so it is a more practical choice for many people.
Tap Water
Tap water is the most convenient and least expensive option for windshield washer fluid. However, it is also the least pure type of water. Tap water contains a variety of impurities, including minerals, salts, and organic matter. These impurities can leave residue on your windshield and damage your washer fluid system over time. If you are using tap water for windshield washer fluid, it is important to use a water filter to remove as many impurities as possible.
