Interior — AUTOMOTIVE — THE FINISHER × Koch-Chemie

Professional-level Automotive Interior Care: THE FINISHER × Koch-Chemie

THE FINISHER × Koch-Chemie offers a clearly structured, coordinated interior care system for plastics, leather, textiles, glass, and displays – for clean, well-maintained, and material-appropriate results without experimentation.

Your vehicle's interior requires products that work cleanly, safely, and are appropriate for the materials. This is precisely why AUTOMOTIVE — THE FINISHER × Koch-Chemie Interior was developed: a curated interior line that combines Koch-Chemie technology with an intuitive, error-preventing workflow. You clean, care for, and protect leather, textiles, glass, displays, and plastics in a clear sequence – first cleaning, then care, separated by materials. The result: fresh surfaces, a pleasant feel, and brilliant, streak-free visibility.

• Clear interior system: Cleaning and care are logically separated – each surface gets exactly the right product.
• Material-appropriate results: Plastics remain matte, leather remains supple, textiles are protected, and glass and displays remain absolutely streak-free.
• Faster, safer workflow: Products interlock and prevent typical errors such as stains, streaks, over-treatment, or dull surfaces.

Interior Cleaning – Clean, Gentle, Residue-Free

The first step in the interior is always a thorough, material-appropriate cleaning. InsideUp is your all-round cleaner for hard plastics and delivers deep pore cleanliness without shiny spots or greasy residues. For leather and textile areas, use LeatherTexClean, which works gently but effectively, does not dry out surfaces, and does not roughen fibers. Highly sensitive equipment such as touchscreens, navigation displays, or piano lacquer is treated with DisplayExpert, which features a fast-evaporating formula that works without alcohol streaks or streaking. The combination of these cleaners ensures that all surfaces are truly free of dirt, skin oils, and deposits – the perfect foundation for subsequent care products.

Care & Protection – Natural Appearance, Pleasant Feel, Stable Effect

After cleaning, you stabilize the material's appearance and provide protection to the surfaces. InsideCare handles the care of interior plastics: not greasy, not shiny, but naturally matte with UV protection and a pleasant feel. On leather, LeatherLock builds a supple protective layer that cares for the material, slightly darkens it, and protects against premature aging – all without a greasy film. Textile surfaces such as seats, headliners, or floor mats are protected with TexLock: a highly functional textile sealant with an easy-to-clean effect that makes it difficult for liquids to penetrate, reduces odors, and significantly simplifies daily cleaning. Through this coordinated care chain, your interior maintains its clean, high-quality look without artificial over-treatment.

Glass & Visible Surfaces – Maximum Clarity Without Streaks

ClearView ensures clear visibility and a high-quality finish in the cockpit. This glass cleaner is highly volatile, streak-free, and specially formulated to deliver perfect results even on difficult, modern glass surfaces. Especially in the interior, where fingerprints, fumes, and smudges occur, ClearView demonstrates its strength: The surface remains brilliant, dry, and free of residues – even in low sunlight or backlight. Together with DisplayExpert, a complete visible surface system is created that safely covers both classic glass surfaces and modern displays.
