What are the advantages of expensive windshield washer fluid over cheaper ones?
2 Answers
Ordinary windshield washer fluid has a minimum operating temperature of -15 degrees Celsius, while more expensive options can function at temperatures as low as -25 degrees Celsius. Below are the specific functions of premium windshield washer fluid: 1. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically possess wetting, penetrating, and solubilizing properties, enabling effective cleaning and stain removal. 2. Antifreeze performance: It significantly lowers the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost. 3. Anti-fog performance: Forms a monomolecular protective layer on the glass surface. This protective film prevents the formation of fog droplets, ensuring clear and transparent windshields with unobstructed visibility. 4. Lubrication performance: Its higher viscosity provides lubrication, reducing friction between wipers and glass to prevent scratches.
I've been driving for over 20 years and tried all kinds of windshield washer fluids. The expensive ones are indeed more reliable. In winter, they have good antifreeze properties, containing alcohol or special solvents that prevent freezing and nozzle blockage even at sub-zero temperatures, while cheap ones often freeze up, making it impossible to spray a single drop of water, which is very dangerous when you can't see clearly on the road. They also have strong cleaning power, quickly dissolving insect stains and grease, unlike cheap products that leave white powder streaks, affecting visibility. Long-term use can also protect the rubber layer of wiper blades, reducing friction and wear, thus extending their lifespan. When driving, clear visibility is key. Spending a few extra bucks brings much more peace of mind, avoiding problems on the road. They work just as well in summer, evaporating quickly in high temperatures without leaving dirt marks. So I suggest car owners not skimp on this—safety comes first.
