How to Make Windshield Washer Fluid?

[Sally]

It is not recommended to make your own windshield washer fluid. DIY windshield washer fluid lacks safety guarantees, especially if the production process is not rigorous enough. The ingredients used may be too simple to achieve the effectiveness of high-quality washer fluid. Homemade washer fluid cannot guarantee performance in terms of cleaning effect and antifreeze properties, and it can easily cause scratches or other damage to the car windshield. Here are some methods to identify quality windshield washer fluid: 1. Check the foam: Shake the washer fluid before purchasing. The amount of foam can indicate its performance—generally, more foam means more activators in the fluid. If the foam is fine and dense, it suggests that the surfactants in the washer fluid are more environmentally friendly. 2. Check the viscosity: The viscosity of windshield washer fluid is also an indicator of quality. The more viscous the fluid, the more ingredients it contains. Turn the bottle upside down and observe the speed at which bubbles rise—slower bubble movement indicates higher viscosity. 3. Check for impurities: High-quality washer fluid is clear and free of any impurities or sediment. After purchasing, turn the bottle upside down to inspect for any impurities.
