Product Info

Koch Chemie GS Greenstar is a highly concentrated, phosphate- and solvent-free, alkaline universal cleaner. Universally usable for the areas of workshop floor and industrial cleaning, interior and exterior cleaning of cars and trucks and engine cleaning
thanks to its enormous dirt and oil carrying capacity.

Special corrosion inhibitors ensure high material compatibility with regard to sensitive components such as eg, anodised aluminium. For use in spray extraction and other carpet cleaning devices we recommend the addition of Kocentschäumer foam inhibitor. Optimally suited as well for biological service water treatment plants. Quick-separating and tested in accordance with ÖNORM 5105 (test concentration 10% solution). VDA conform to class A: reaction time max. 5 min, max. application concentration 1:3

Areas of use
Cars, recreational and commercial vehicles, workshop and industrial floors, machinery, etc.

Recommendations for use
Depending on the dirt accumulation: cleaning vehicle exteriors and engines use a 1:5 to 1:30 solution. Apply over the whole surface, allow to react for a short time, and use a high-pressure cleaner to rinse off thoroughly.
Cleaning vehicle interiors and textiles use a 1:10 to 1:20 solution. Remove product resides with a damp cloth or a wet/dry vacuum cleaner. Workshop and industrial floors use a 1:40 to 1:120 solution. VDA conform to
class A: reaction time max. 5 min, max. application concentration 1:3

Do not use on hot surfaces. Do not let dry. Before using, check suitability and compatibility.

  1. GM Details

    Greenstar is an incredible product delivering superb cleaning power for very little money.
    Fantastic for anything from interior fabrics to engine bay plastics.
    I use it at 20-1 for interior use and a couple of sprays and agitating with a detailing brush foams up nicely and wipes away very cleanly with a damp microfibre and dries to a lovely OEM look.
    Up to 3-1 for engine bays and wheel arches breaks down grime with ease and leaves no residue behind, I love it.
