  • The leather-care system for clean & protected vehicle leather from THE FINISHER × Koch-Chemie

    THE FINISHER × Koch-Chemie gives you a perfectly matched two-step system of leather cleaning and leather care – for deep-clean, supple and long-term protected leather surfaces in your car.


    Leather in a car is demanding: it reacts badly to the wrong cleaners, loses moisture over time, goes dull or brittle and picks up wear marks fast. That's exactly where AUTOMOTIVE — THE FINISHER × Koch-Chemie Leather steps in. The system cuts down on mistakes, works with the material rather than against it and walks you through two clear steps: clean – care. LeatherTexClean and LeatherLock work as a logical duo that keeps leather surfaces clean, supple and hard-wearing, without ever leaving them greasy or over-conditioned.

    • System logic for leather: clean first, then care – clean, safe, efficient.
    • Gentle, effective cleaning: deep into the pores, colour-stable, kind to the material.
    • Natural care: a supple surface, UV protection, no glossy residue.

    LeatherTexClean – deep-pore, colour-stable cleaning for every type of leather

    LeatherTexClean is the base of any good leather-care routine. The formula pairs mild surfactants with real cleaning power to pull sweat, skin oils, light dirt and wear marks out of the pores without drying the leather out. It really shows its strength on modern automotive leathers – pigmented, grained or part-synthetic: a controllable action, a matt, natural look and a fresh feel to the material. Even mixed leather-and-textile areas come up evenly clean, with no colour differences. Afterwards the leather is neutral, grippy and perfectly prepped for the care step with LeatherLock.

    LeatherLock – a nourishing protective film for supple, UV-stable leather

    Once it's clean, you lock the surface in with LeatherLock. This care step blends gentle conditioners with UV protection and lays down as a thin, completely invisible protective film over the leather. No greasy shine, no oily edges – instead a natural, slightly deepened feel that keeps the original grain of the material. LeatherLock slows down how fast dirt settles back in, improves grip and heads off the usual signs of ageing like dryness and lightening around the seams. Ideal for seat surfaces, the steering wheel, the gear boot or door cards.

    The perfect combination – clean, supple and long-lasting leather care

    The full effect only shows when both products work together: LeatherTexClean pulls dirt out of the pores and grain, LeatherLock builds the care on top. The result is leather that looks clean, feels good under your hand and stays stable for longer. On daily drivers, lease returns, light-coloured leather or heavily used seats, the FINISHER leather approach pays off day-to-day.
