KOCH CHEMIE: The German reference in detailing chemistry

KOCH CHEMIE is a German brand that appeared relatively recently in the detailing world, yet has existed since 1968 in the large-scale automotive washing sector.

It is one of the few brands that centralizes research and development, manufacturing, and product distribution all in one place.

What makes this brand stand out is its impressive product range. Highly technical and Pro-oriented products, with a quantity/efficacy/price ratio that is often very competitive.

Range Overview:

The first thing that catches your eye when looking at the KOCH CHEMIE product range is the very "structured" labeling: color coding, acronyms to identify products, information on the pH of products, the Cut/Gloss level of polishes, etc.
In short, you can feel the professional and highly technical side of the brand.

Identification:

As mentioned, at KOCH CHEMIE, everything is very well organized, coded, and each color, index, or superscript has its own importance and meaning.

Each product category has its own color. Green, for example, is reserved for car preparation products, yellow for chemical washing products such as pre-wash foams and shampoos, and black for polishes and other paint/varnish treatments.

You will always find the product's own initials along with a few key pieces of information.

So if we take the previous polish H8.02 as an example (since replaced by the H9.01), we get: Heavy Cut (polish with strong cutting power), cut level 8, 2nd update, with an exact cut of 8.5 and a finish level of 5.0.

Also, regarding the excellent Green Star, we have the pH indication of the pure product (here 12.5, meaning a highly alkaline product).

KOCH CHEMIE is therefore a brand that allows you to identify and decode a product very quickly, which is a real advantage especially for enthusiasts.

Indeed, it should be noted that KOCH CHEMIE offers many highly technical products more suited for professionals or in very large volume packaging (5L, 11kg...). A real financial advantage for heavy users, it is above all interesting that the majority of products are pure concentrates to be diluted. You can therefore easily vary the product's efficacy through dilution.

What are the best products in the KOCH CHEMIE range?
In reality, there is no bad reference in this brand. The only real criticism would be that the range is so extensive that it can be difficult to choose the right product for your needs.

That said, there are some must-have references within the range. For example Gs (Green Star), the APC with an almost unbeatable efficacy/price ratio. Po (PolStar) for cleaning fabrics, leather, and alcantara at a neutral pH. Also worth mentioning is the excellent and highly effective Eulex (Eu) for tar and sticky residues, or As (AutoShampoo), a universal body shampoo at a neutral pH.

Are KOCH CHEMIE polishes any good?

You cannot talk about KOCH CHEMIE without mentioning their polish range, which is excellent and even a benchmark in the detailing world. The brand offers various abrasives, ranging from Hard Compounds to high-finish polishes and even All-In-One products. The quality of the polishes comes through in their smooth working consistency, minimal dust generation, their very strong cut, and their impeccable finish for compounds (H9.02). The finishing polishes (M3.02) deliver a stunning result in terms of gloss and a complete absence of residual defects. The intermediate (F6.01) is an ultra-versatile polish that allows "single stage" corrections without having to go through all the steps.

The cut and finish indicators on the labels are clear and allow the detailer to find their way quickly and easily.

The pads paired with the polishes are also excellent and feature an identical color-coding system to once again make identification easier.

Is KOCH CHEMIE only for professionals?

No, all users, enthusiasts or professionals alike, can work with the KOCH CHEMIE product range.
However, the variety of highly technical products and the very large packaging sizes (5L, 11kg, 22kg and even 225kg) mean it will be the go-to brand for detailing and even valeting professionals.
Those with high product consumption will find their financial interest in it, but enthusiasts will appreciate the efficacy of the products.

Does KOCH CHEMIE limit itself solely to chemical products and polishes?

The brand offers a good number of accessories, such as polishing pads as mentioned earlier, brushes of excellent quality and once again perfectly color-coded to indicate which surface to treat, as well as various brushes and bottles. Buckets, microfibers, gloves, etc. are further references easily found in their range.

Conclusion:

KOCH CHEMIE has become an essential brand in the global detailing landscape. The brand's seriousness, product range, large volumes for professionals, and the efficacy and technicality of the products speak for themselves. Anyone who tries a product can only adopt it. The often pure-concentrate products are also appreciated for substantial savings.
You cannot go wrong choosing a KOCH CHEMIE product. Another advantage is that the German company designs its formulas, manufactures them, and distributes them, which is quite rare among other detailing brands.

Accessories such as pads, gloves, and brushes may be more debatable, although they are also very good, but chemistry remains their undisputed strong point.
