Just buy it, its well worth the money. Super versatile. This product literally does it all. Obviously use on cool dry surfaces, 10:1 dilution is perfect for all applications. Put it in a foam cannon and it makes the best ore-wash. 10/10

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 product I recommend this APC !!

Highly dilute-able, use it for my detailing business, easy to use, Works amazingly when proper dilution, the value is very good for the money! You can get so much more out of the product, a go to for me daily cleaning!

best bang for buck. cleans almost anything. if you dilute it, it lasts a decade. Smells ok.

High quality product! I live in the Rocky Mountains, my truck and wife’s SUV are constantly getting covered in dirt, bugs, etc. I use this as a pre-wash and on the interior (different dilutions). Works great to get the stains out with a brush. Our kids leaves impressive and creative messes. It’s an excellent addition to the cleaning arsenal.

This product cleans extremely well, At first i had forgot to dilute it so please dont make that issue like I had. It foams really well and doesn't smell bad.

Odor is not strong, and can be used on almost anything from exterior to interior. Saves lots of time and money

Really good product versatile. Can go a really long way with diluted ratios. Powerful cleaning products use carefully.
