  • COLOURLOCK × Koch-Chemie DE: Premium leather care & repair — since 1995

    COLOURLOCK is a German premium brand for professional leather care, cleaning and repair at OEM quality. Developed by Lederzentrum GmbH and made in Germany, the brand is built around going easy on the material, staying simple to use and delivering professional, manufacturer-grade results — for leather in the car, at home or in a pro setting.

    COLOURLOCK was founded in 1995 by the German Lederzentrum and has been part of the Koch-Chemie group since 2023. Every product is developed, tested and made in Germany. The focus is on maximum effect with the lightest possible touch on the material — which means the leather stays natural, supple and long-lived.

    COLOURLOCK covers the whole job, from gentle cleaning through conditioning to a colour refresh or repair. The range includes the leather cleaner (Mild and Strong), the leather protector, the leather sealant and liquid leather, plus the repair-and-colour sets sold as ‘Leder Fresh’. Everything is built to be easy to work with, whether you’re a professional detailer or a keen enthusiast doing it yourself.

    One thing that really sets the brand apart is its research into protecting the material: COLOURLOCK blends skin-friendly surfactants, quality waxes and UV stabilisers that don’t weigh the leather down but keep its natural structure intact. That knocks back the usual damage — drying out, fading or fine cracking — by a long way.

    Day-to-day the job usually runs in three steps. First you clean the leather properly — with the mild or the strong cleaner, depending on how dirty it is. Then comes the conditioning with the leather protector or the sealant, which brings back suppleness, UV protection and a nice feel under the hand. On older or heavily used surfaces, products like liquid leather or Leder Fresh come in to make colour breaks and scratches disappear. The result is always the same: clean leather with a natural matte finish, an authentic grip and lasting protection.

    Since joining Koch-Chemie GmbH, COLOURLOCK keeps pushing its line forward — with a focus on sustainable formulas, wider uses and sets dialled in for detailers. That keeps COLOURLOCK not just the benchmark in leather care, but increasingly a system brand for looking after the whole interior.

    COLOURLOCK is for anyone who doesn’t just want to ‘clean’ leather but genuinely keep it — whether it’s in a luxury car, a classic or high-end furniture at home. The products are well thought through, safe to use and give visible results with no risk to the colour or the surface.
