Koch-Chemie Green Star universal cleaner

Green Star is a highly concentrated, phosphate-and solvent-free, alkaline universal cleaner formulated by Koch-Chemie. Originally developed for the German automotive and industrial sectors, it is widely recognized for its high dirt and oil-carrying capacity, making it suitable for workshop floors, industrial cleaning, and both interior and exterior vehicle detailing.

In 2020, Koch-Chemie was acquired by the French family-owned company Arkema, specifically through its Bostik subsidiary. Despite this change in ultimate ownership, the brand maintains its historical identity as a premium German manufacturer, with its primary production and research facilities remaining in Unna, Germany. The product is frequently used in high-end detailing and industrial applications due to its material compatibility with sensitive components like anodized aluminum.
