Koch-Chemie Green Star

• Description

  Koch-Chemie Green Star 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 bay cleaning thanks to its enormous dirt and oil carrying capacity. Special corrosion inhibitors ensure high material compatibility with regard to sensitive components such as anodized aluminum. For use in spray extraction and other carpet cleaning devices we recommend our Detail King Extractor Defoamer.

  What’s in the bottle:

  • Alkaline universal cleaner concentrate
  • 1L and 5L sizes available
  • Phosphate-free and solvent-free formula
  • Safe on anodized aluminum thanks to built-in corrosion inhibitors
  • 1:5 to 1:120 dilution range (heavy degreasing to floor maintenance)
  • Lifts dirt, road film, oil, brake dust, engine bay grime, and shop floor build-up

  Use cases: engine bay degreasing, wheel barrel cleaning, tire dressing prep, exterior plastic trim cleaning before dressing, bug and road film removal, shop floor scrub-down. Alkaline chemistry is the right tool for those jobs and the wrong tool for finished leather, Alcantara, or factory waterproofing, where it strips the protective finish. A 1L bottle yields 6 to 121 liters of working solution depending on the ratio. For leather and Alcantara interiors, reach for the neutral Koch-Chemie Pol Star; for gum, ink, or asphalt stains, reach for the Koch-Chemie Eulex solvent.

  Who this is for

  • Detail shops running engine bay packages and full exterior decon as part of the service menu
  • Mobile detailers wanting one APC concentrate that covers wheels, tires, trim, and engine bay
  • Body shops and reconditioning crews dealing with heavy grease, road tar, and oily contamination on used inventory
  • Shop owners who also need a workshop floor and bay cleaner so a single drum covers detail-side and facility-side cleaning

  Dilution Guide

  Use Case	Dilution	Notes
  Engine bay degreasing	1:5 to 1:10	Cover sensitive electronics; rinse with low-pressure water
  Wheel barrels (light brake dust)	1:10	Pre-rinse first; agitate with a wheel brush
  Tire dressing prep	1:10 to 1:20	Strips old dressing and road film so new dressing bonds
  Exterior plastic trim cleaning	1:20	Always dress after; never leave Green Star on trim dry
  Bug and road film on paint	1:20 to 1:30	Use as a pre-soak before contact wash
  Vehicle interiors and textiles (carpet, mats)	1:10 to 1:20	Damp cloth or wet/dry vacuum wipe-up; avoid leather and Alcantara
  Workshop floors and industrial	1:40 to 1:120	Mop, scrub, or auto-scrubber depending on soil load

  General rule: start dilute and go more concentrated only if the job needs it. Always rinse or wipe Green Star off the surface; never let an alkaline cleaner dry on paint, trim, or aluminum. Test on an inconspicuous area when you’re unsure of the substrate.

• For Best Results

  Dilute to the job, give it a short dwell, and rinse or wipe clean:

  • Exteriors and engines (1:5 to 1:30): coat the whole surface, let it work briefly, then rinse thoroughly with a high-pressure cleaner.
  • Interiors and textiles (1:10 to 1:20): lift product residue with a damp cloth or a wet/dry vacuum.
  • Workshop and industrial floors (1:40 to 1:120).
