What Is Windshield Washer Fluid Made With?

Knowing what windshield washer fluid is made with helps vehicle owners know what steps they need to take to secure the chemicals, which can be harmful to children and pets. It also lets people know what they are putting into the environment when they use their cars.

Methanol

According to Medlineplus.gov, the main ingredient in windshield washer fluid is methanol. This material is toxic to humans and animals but has the ability to break though bug tar, which is why it is still used.

Blue Dye

The most common dye used in windshield washer fluid is powdered blue dye, according to Keystone Dyes.

Water

According to Patentstorm.us, U.S. Patent 5932529 states that 52 to 81 percent of a gallon of wiper fluid is water. This means it is combustible at high temperatures.

De-Icer

The chemical used for de-icing in windshield washer fluid is ethylene glycol, also a common chemical in automotive antifreeze.

Alternatives

Manufacturers that offer chemical-free alternatives have started making wiper fluid from plants and vegetables. These won't harm the air or soil.
