The Koch-Chemie Product System Explained: Colour Codes, the Polish System & Where to Start
Koch-Chemie is a German manufacturer that sells its chemicals as a coordinated system rather than loose bottles: the polish line is coded (H = heavy cut, M = micro/medium, P = polish/finish), the Star line covers strong cleaners, and pH runs from 1 (Finish Spray) to 12.5 (Green Star). For a first kit, start with NanoMagic Shampoo (pH 5, 1:200), Gentle Snow Foam (pH 7.5, coating-safe) and Green Star (alkaline APC).

Where to start
- NanoMagic Shampoo — pH 5, 1:200; a mild, high-sheeting weekly wash that is easy on wax and coatings.
- Gentle Snow Foam — pH 7.5, 1:50; a neutral, coating-safe pre-wash foam for loosening grime before contact.
- Green Star — pH 12.5, 1:5–1:30; the workhorse alkaline APC for heavy pre-wash, fabric and trim degreasing.
- Magic Wheel Cleaner — pH 5 acidic wheel cleaner with a colour-change reaction for brake-dust and fallout.
- One Cut & Finish P6.02 — the single-step "P" polish that cuts defects and finishes down in one pass.
- Finish Spray Exterior — pH 1 low-pH quick detailer for a streak-free, water-spot-resistant show finish.
How to choose
Read the code, not the marketing: the polish line's letter (H heavy → M micro → P polish/finish) tells you how aggressive it is, so match the letter to your defect severity and always test the least aggressive first. On the chemical side, let pH decide safety — neutral Gentle Snow Foam (7.5) and mild NanoMagic (5) are the coating-safe defaults for regular use, while Green Star (12.5) is a dilute-and-rinse heavy cleaner reserved for grime you cannot wash off. Use the calculator on each product page to convert a ratio like 1:200 into a real bottle mix.
FAQ
What do the Koch-Chemie polish codes mean?
The letter is the cut class: H is heavy cut for deep defects, M is micro/medium cut, and P is a polish or one-step cut-and-finish. Start with the least aggressive that clears your defects.
Is Koch-Chemie Green Star safe on every surface?
Green Star is an alkaline APC (pH 12.5). Dilute it per the label (1:5–1:30), work cool, shaded panels, never let it dry, and rinse fully — undiluted or dried alkaline cleaner can stain trim and strip wax or sealant.
What is the difference between Gentle Snow Foam and Green Star?
Gentle Snow Foam is a neutral (pH 7.5) coating-safe maintenance foam for weekly pre-wash. Green Star is a strong alkaline (pH 12.5) pre-wash/APC for heavy grime — more cutting power, but it must be diluted and rinsed carefully.
