This is such a great cleaner and very versatile. Totally worth the money since this is a concentrate, and can be diluted for multiple uses. Strong enough to clean a variety of surfaces, but not too strong so it doesn't damage them. Used on carpet with an extractor, and worked better than my carpet shampoo. This bottle will last a very long time!

Overall, Koch-Chemie Green Star is an indispensable tool for any detailer or car enthusiast seeking a product that delivers exceptional cleaning performance.

I love this product, its highly concentrated which makes it very cost efficient, you can dilute it in many ways depending on the use. I dilute 1:20 for interiors, 1:5 for carpets and 1:3 as a pre-wash on a foam cannon. Cleans very well and doesn't leave any residue behind.

You can clean everything with it

High quality and you can dilute this quite a lot. Its actually quite mandatory to dilute at least to a 1:20 or more if you plan to clean your car interior. Make sure to apply protection right after the use of this product to avoid any damage to the interior. Also if you plan to use on leather, you can, its basically the same as PolStar but with higher PH (more alkaline) so I would say to test a dilution of 1:30 or more depending on how dirty the leather is.

Works great as an APC. Super dilutable, and will last you ages

I’m surprised it took me so long to find this. Great multi-purpose concentrate. For someone who details his car as a hobby, it feels like a lot of money at $25 for 1L, but considering you can use it as a general purpose cleaning solution for situations beyond your car, I find it pretty worth it. No silly, exaggerated scents either unlike so many other brands either.
