The Finisher LeatherLock | Leather Care 500mL

Koch Chemie LeatherLock a leather protection product designed to help protect smooth leather from wear, dye transfer and everyday contamination after cleaning.

Features & Benefits

• Leather protection for smooth leather surfaces
• Helps reduce dirt adhesion and dye transfer
• Ideal after leather cleaning
• Suitable for seats, bolsters and high-contact areas
• Maintains a natural interior feel
• Useful for new and light-coloured leather
• Professional protection step for interior detailing

Koch Chemie LeatherLock is designed as a protection step after leather has been properly cleaned. Modern leather, especially light-coloured seats, can quickly show dye transfer, body oils and wear marks on bolsters and high-contact areas. LeatherLock helps create a protective barrier that makes the surface easier to maintain.

This product is particularly valuable on newer vehicles, pale interiors and premium leather cabins where prevention is easier than correction. For best results, clean the leather first with Koch Chemie LeatherTexClean or Pol Star, allow it to dry, then apply LeatherLock evenly.

LeatherLock is not intended to hide dirty leather. It performs best when applied to a clean, dry surface as part of a regular maintenance and protection routine.

Pro Tip

Apply LeatherLock early on new or near-new leather. Preventing dye transfer and abrasion is much easier than correcting it once it has bonded into the surface.
