Highly dilutable great for interior detailed or exterior pre wash for maintenance lid can leak but not end of the world

Good stuff, produces good foam

Got it love this product good for almost everything for detailing a vehiclePre wash , insect remover, interior apc , engine bay… 10 out of 10

It’s a really good product to use if you like washing your own car like me. It works amazing as a pre wash for a car would definitely recommend

I didn’t know to much about Koch Chemie products but i did search about it I watched some youtube videos, everybody is talking good stuff about it so I bought and I Love it!I dilute 10:1 (10 parts water and 1 part product) and i can clean everything, any surface, Inside, outside, the engine, even as a Pre Wash! I LOVE IT .I tried other brands and products before, Koch Chemie is not expensive at all, and it is a great productI recommend this APC !!

Green Star without a doubt is the best alkaline APC on the market.For exterior, I use it 1:10 in a foam cannon (can be used stronger if needed). 1:10 in a spray bottle for pre treating specific areas or bugs (not the best bug remover, but it works). 1:20 for interior (use wisely, don’t spray on sensitive areas) leather, plastic panels, mats, pedals.It foams fairly well for being an apc, but don’t expect crazy snow foam. It is also a stronger chemical smell, so I would advise using a mask when you can. Also this will leave bad streaking on paint if left to dry, so work diligently.

Great prewash for every car I detail, prevents swirling and marring

This stuff just works
