Koch Chemie AWH Alkali Wheel Cleaner:

Koch-Chemie Alkali Wheel Cleaner is a powerful alkaline wheel cleaner that will quickly and thoroughly clean rims and wheels. The combination of special dirt carriers and an alkaline solution work together to dissolve and disperse brake dust/iron particles, similarly to acidic wheel cleaners. This formula generates minimal foam for excellent moistening and minimal fogging, allowing for its quick and convenient removal properties.

Product should not be used on hot surfaces or left to dry on the surface. Do not use on surfaces sensitive to alkalis, such as aluminium or chrome.

5 litre container.
