What are the differences between coated windshield washer fluid and regular windshield washer fluid?
2 Answers
Here are the specific differences between coated windshield washer fluid and regular windshield washer fluid: 1. Coating effect: Coated windshield washer fluid has the ability to coat the glass, and long-term use can form a protective film on the surface of the car's glass. In rainy weather, it is less likely to retain water, providing the driver with a stable and clear field of vision, thereby improving driving safety to some extent; whereas regular windshield washer fluid does not have this function. Regular windshield washer fluid used in vehicles mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surface-active agents. It has practical functions such as cleaning, antifreeze, antistatic, and anti-corrosion. 2. Cleaning effect in rain and snow: Coated windshield washer fluid can provide better cleaning performance in rainy or snowy weather, maintaining good visibility; whereas regular windshield washer fluid is slightly inferior in this aspect.
When it comes to the difference between coated glass cleaner and regular glass cleaner, I feel there's quite a noticeable distinction in practical use. I remember the last time I used regular glass cleaner—during rainy days, I had to frequently spray and wipe the windshield, otherwise water droplets would cling to it, blurring my vision. After switching to coated glass cleaner, water droplets just roll right off after spraying, eliminating the need for multiple sprays. The key is that the coated version forms a thin film on the surface, making the glass more hydrophobic so rainwater slides off faster, significantly improving nighttime visibility. Regular glass cleaner is cheaper, but its cleaning effect is short-lived. It works fine for bird droppings or tree sap but tends to leave water stains. In winter, regular glass cleaner may freeze, requiring an antifreeze variant, while the coated version usually comes with built-in antifreeze properties, making it more hassle-free. I've been using the coated type for almost a year now and noticed less wear on my wiper blades, though the cost is indeed more than double. For friends who don’t drive often, regular cleaner might suffice, but for those who frequently take long trips or live in rainy areas, I’d recommend trying the coated version—it offers a substantial safety upgrade.
