Methanol – 99

This mixture consists of 99.92% methanol and 0.08% acetone. The reason why this combination works well for windshield washer fluid is because both of these chemicals are commonly used in that specific product. Methanol is a type of alcohol that is known for its solvent properties and ability to dissolve grease, dirt, and grime. Acetone, on the other hand, is a fast-evaporating solvent that is effective in removing paint, varnish, and other coatings. Together, methanol and acetone provide a powerful cleaning solution that effectively removes grime and dirt from windshields, leaving them sparkling clean. Additionally, the addition of these chemicals to windshield washer fluid helps to prevent freezing, ensuring that the solution remains usable even in cold weather conditions.
