Koch-Chemie Green Star is a highly concentrated alkaline all-purpose cleaner designed for exterior, interior, and industrial cleaning applications. This professional-grade APC removes heavy dirt, grease, oil, insect residue, and road film from automotive and commercial surfaces. The formula delivers strong cleaning performance while allowing controlled dilution for different use cases.

The advanced alkaline cleaning system breaks down stubborn organic and oily contamination through powerful emulsification. Green Star penetrates dirt layers and lifts contamination from surfaces for easy rinsing or wiping. The concentrate supports a wide range of dilution ratios, making it suitable for heavy-duty degreasing as well as lighter maintenance cleaning. This flexibility improves chemical efficiency and reduces the need for multiple specialty cleaners in professional environments.

Green Star is widely used for engine bay cleaning, wheel wells, exterior pre-cleaning, industrial equipment cleaning, and heavy interior soil removal. It is suitable for use on paint, plastics, rubber, metal, and durable interior materials when properly diluted. Professional detailers, fleet maintenance teams, automotive workshops, and industrial cleaning operations rely on it for high-strength cleaning performance. It is especially effective in removing road grime, grease buildup, and environmental contamination from high-contact surfaces.

Using Green Star improves cleaning workflows by reducing manual scrubbing time and increasing surface cleaning efficiency. It prepares vehicles for detailing steps such as washing, polishing, or protection application. When used correctly, it supports safe and consistent results across demanding cleaning environments. Regular use helps maintain cleaner engine bays, wheels, and exterior components in professional applications. Shop more professional cleaning solutions in our Exterior & Engine Cleaning category.
