The composition of the anti-freeze for cars and the requirements for it

Legal manufacturers under popular brands produce high-quality and safe washer. It remains to choose and buy an anti-freeze solution for the current weather.

Windshield washer fluid is used to improve visibility in the car. For winter, this is an anti-freeze for cars, which includes components that reduce the crystallization temperature. A high-quality windshield washer does not contain substances hazardous to humans.

What do you pay attention to when studying the composition

In summer, plain water can also serve as a washer, but in winter, liquids that do not harden are used. The composition of the antifreeze includes components that clean the windshield or headlights at low temperatures. Such a product should not be toxic and leave stains.

Substances in the anti-freeze for car windows:

1. Alcohols that lower the freezing point.
2. Detergents are surface-active components that remove dirt and stains on glass well.
3. Stabilizers that retain the characteristics of the liquid for a long time.
4. Denatured alcohol with a repulsive taste and smell and flavors are pleasant fragrances.
5. Dyes indicating the alcohol content of the composition.

The composition of the anti-freeze for the car

When buying a glass cleaner, you need to pay attention to the labeling for smell and freezing threshold.

Alcohol used

In winter, components that reduce the crystallization temperature are added to the anti-freeze for a car. The basis of such a liquid is a non-toxic solution of monohydric alcohols in water.

Ethanol has a high price due to excise duty. In addition, manufacturers rarely choose this substance for windshield washer due to the strong alcohol smell. Methanol is prohibited to exclude poisoning in cases where non-freeze enters the human body. More often, isopropyl alcohol is used in the washer, which is distinguished by an unpleasant amber.

The presence of a strong odor

Windshield washer fluid contains substances that irritate the mucous membranes and respiratory organs. Some anti-freeze components can cause poisoning. The most dangerous alcohol, methanol, has a faint odor.

Glass washer fluid

Isopropyl, which is usually used as part of a glass washer produced in accordance with GOST, has a sharp amber, which fragrances hardly interrupt. However, good quality anti-freeze evaporates quickly, so the smell does not penetrate into the car interior.

• the composition should not freeze at low temperatures;
• be safe for humans and inert to plastic and car paintwork.

Frost resistance is provided by the anti-freeze base - alcohol. The higher the concentration, the lower the application temperature of the product. The inertness of the anti-freeze to the automotive surface is provided by stabilizing components, and safety for humans is ensured by non-toxic additives.

The windshield washer of the official manufacturer must be marked, instructions for use and a certificate of conformity. The TOP-rating of non-freezing in Moscow is headed by the brands LIQUI MOLY, Hi-Gear, Gleid Nord Stream.
