What is windshield washer fluid?

Windshield washer fluid is a liquid solution that is used to clean a vehicle’s windshield. It is typically made of a combination of water, detergents, and sometimes alcohol or antifreeze. The fluid is sprayed onto the windshield from the vehicle’s wiper jets, which are located at the base of the windshield.

There are various types of windshield washer fluids available in the market, including summer and winter formulas. The former typically has a lower concentration of antifreeze, while the latter contains a higher concentration to prevent the fluid from freezing when it is used in cold temperatures. Some windshield washer fluids also contain additives such as bug and tar remover, rain repellent, or de-icer to improve their effectiveness.

The harmful effects of traditional windshield washer fluids

Traditional windshield washer fluids are incredibly harmful to the environment and can contaminate both ground and surface water sources. The main ingredients in these fluids are methanol, ethylene glycol, and ammonia, all of which are toxic and can negatively impact aquatic life.
