In some domestic glass waters, because alcohol is expensive, methanol is used to prevent freezing in the water. Methanol is a highly toxic fluid and is soluble in all organic solvents in all proportions. Even a small amount of methanol creates danger for living organisms and the environment. For example, when 10g of methanol is used pure, it can cause deadly danger to human.
Glass waters containing methanol evaporates during use and passes through the air ducts, causing harm especially to babies and pregnant women. With long-term use, it damages the health of the occupants over time. It may cause permanent damage and defects on the vehicle surface. These products, which are known as under-stairs manufacturing and have no standards, besides being harmful to health, harden the wiper blades and cause scratches on the glass. For an enjoyable and safe ride, we recommend that you avoid products containing Methanol. Instead of these products, use Wieberr Antifreeze Glass water with alcohol and glycerin content, fragrant, cleaner additives and a guarantee of non-freezing.
