Glass water, commonly known as windshield washer fluid for automobiles, is a consumable item in car maintenance. It possesses properties that are not found in regular water.

Many car owners may overlook the importance of windshield washer fluid and resort to using tap water as a substitute when it's unavailable, which is not advisable.

Automotive windshield washer fluid serves the purpose of cleaning but also aids in improving the driver's visibility, thereby avoiding potential hazards due to unclear vision during driving.

1. Ethanol forms a thin film on the car's glass surface, removing dirt without leaving residue.

2. Polysulfone and polyvinyl alcohol cause water droplets to condense on the glass surface, reducing humidity and minimizing fogging, thus enhancing visibility and driving comfort.

3. Automotive windshield washer fluid also exhibits specific antioxidant properties, preventing rust spots on the glass surface, thereby prolonging its lifespan. It also provides some resistance to UV radiation, shielding against solar radiation and preventing the interior temperature from rising.

How much windshield washer fluid should be added for optimal performance?

Generally, adding windshield washer fluid should be done with precise measurements and correct procedures to ensure the best driving experience and driver safety. Therefore, it's essential to know the appropriate amount to add.

The quantity depends on the size of the vehicle, the size of windows, and the number of windows. Adding 1/4 to 1/2 bottle of windshield washer fluid is generally sufficient. It's crucial to apply it evenly, with specific areas possibly requiring slightly more but not exceeding half a bottle.

Moreover, when cleaning windows, avoid using cloths, tissues, or towels soaked in windshield washer fluid to prevent altering the fluid's proportions. Overuse of windshield washer fluid can cause windows to become damp, leading to issues like streaking and reduced visibility.

Four steps to help you choose the right windshield washer fluid:

The composition typically includes cleansers, halogens, anti-caking agents, bacteriostats, thickeners, etc. Pay attention to choosing a cleanser with strong degreasing capabilities that is gentle and non-irritating to the eyes.

2. Choose products that are easy to use:

Opt for windshield washer fluids less prone to spillage to minimize waste and ensure convenient operation.

3. Consider special circumstances:

If driving often occurs in rainy or snowy conditions, choose windshield washer fluid with anti-icing and anti-crystallization properties to prevent ice buildup on the glass and ensure safety.

4. Select products with good protective functions:

Windshield washer fluid may contain ingredients that protect the glass, making it more resistant to UV rays and acid rain corrosion, thus extending its lifespan.

In conclusion, selecting the appropriate windshield washer fluid is essential for maintaining clear visibility, ensuring driving safety, and prolonging the lifespan of automotive glass.
