Can Windshield Wipers Use Tap Water?

[OSimon]

Windshield wipers should not use tap water. Most tap water has hard water quality or contains impurities, which results in poor cleaning performance, reduces glass transparency, and can form deposits over long-term use. It may also clog the pipes and damage the wipers. In cold winter weather, tap water can easily freeze, failing to provide protection for the car's windshield. Windshield washer fluid is a super-concentrated automotive glass cleaner with unique properties such as non-stickiness, anti-static, anti-corrosion, dustproof, antifreeze, acid rain resistance, and UV protection. It helps maintain the gloss and lubrication of rubber and plastic materials, preventing hardening and cracking. The windshield wiper is a blade structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly.
