Can Tap Water Be Used as Windshield Washer Fluid for Cars?
1 Answers
Car windshield washer fluid cannot be replaced with tap water. Lubrication: If you have ever used tap water as "windshield washer fluid," you will notice that the wipers produce loud friction noises when wiping the glass. This is because tap water lacks lubricating properties. Using tap water instead of proper washer fluid not only fails to clean effectively but also severely damages the wipers and windshield, leading to the need for frequent wiper replacements. Tap water lacks antifreeze properties: When the external temperature drops below freezing (0°C), tap water will freeze. Therefore, during cold winters, "windshield washer fluid" made from tap water becomes completely ineffective for cleaning. This obstructs the driver's view and poses a significant safety hazard. Moreover, frozen tap water can expand and crack the fluid reservoir, necessitating a replacement—a situation you would regret. In contrast, proper windshield washer fluid contains antifreeze agents, allowing it to function normally even in freezing winter conditions. Windshield washer fluid also offers anti-fog and anti-static properties: Winter often brings fog, which can cling to the windshield and severely impair visibility, making timely removal essential. Additionally, static electricity is common in winter, and proper washer fluid can easily address these issues.
