Koch Chemie Multi Star N is a highly concentrated, phosphate- and NTA-free, alkaline, high-foaming pre-cleaner designed for car and truck prewashing. Its advanced formula combines high-quality complexing agents and special surfactants to rapidly dissolve stubborn contaminants such as insects, bird droppings, environmental grime, and rim dirt. This makes it ideal for heavily frequented car washes and non-contact high-pressure washing. Special corrosion inhibitors ensure compatibility with sensitive materials like anodized aluminum. Additionally, Multi Star N is suitable for copolymer dewaxing and works well in biological service water treatment plants. It is quick-separating in accordance with ÖNORM 5106 and conforms to VDA standards for classes A and B.
