THE FINISHER "LeatherTexClean" Leather and Textile Cleaner
Mild cleaner for smooth leather and textile surfaces
THE FINISHER × Koch-Chemie offers a perfectly coordinated two-step system of leather cleaning and leather care – for pore-deep clean, supple, and long-term protected leather surfaces in your vehicle.
Vehicle leather is demanding: it reacts sensitively to incorrect cleaners, loses moisture over time, becomes dull or brittle, and quickly shows signs of wear. This is exactly where AUTOMOTIVE — THE FINISHER × Koch-Chemie Leather comes in. The system reduces errors, works in a material-appropriate way, and clearly guides you through two steps: clean – care. LeatherTexClean and LeatherLock function as a logical duo that keeps leather surfaces clean, supple, and resilient, without making them look greasy or over-treated.
LeatherTexClean is the basis of good leather care. The formulation combines mild surfactants with high cleaning power to dissolve sweat, skin oils, light dirt, and signs of wear from the pores without drying out the leather. Especially on modern automotive leathers – pigmented, grained, or semi-synthetic – the cleaner shows its strength: controllable effect, matte, natural look, and a fresh material appearance. Even leather-textile mixed surfaces are evenly cleaned without creating color differences. The leather is then neutral, grippy, and optimally prepared for the care application with LeatherLock.
After cleaning, you stabilize the leather surface with LeatherLock. The care combines gentle conditioners with UV protection and forms a thin, completely unnoticeable protective film over the leather. No greasy shine, no oily edges – instead, a natural, slightly darkened feel that preserves the original material structure. LeatherLock reduces rapid re-soiling, improves grip, and prevents typical signs of aging such as dryness and lightening in the seam area. Ideal for seat surfaces, steering wheel, gear shift boot, or door panels.
The full effect only comes into play with both products working together: LeatherTexClean loosens dirt from pores and structures, LeatherLock builds up the care. The result is a leather appearance that looks clean, feels pleasant, and remains stable longer. Especially for everyday vehicles, lease returns, light-colored leathers, or intensively used seats, the FINISHER leather logic offers clear advantages in daily use.
