Today's focus: a shiny steering wheel is either skin oils or worn grain, and only the first one comes off. To the leather cleaners

From the blog: a taped-off test patch shows within minutes whether cleaning the wheel is still worth it. Read the wheel guide

From Thursday: it turns wet, so the protection has to go on first for the water to run off instead of clinging. Go to paint sealants

Today: at 33 degrees every product dries on the paint, so work in the shade or early in the morning. Go to car washing

Best seller: the Koch-Chemie Green Star „Gs“ covers four dilutions from 1:5 to 1:50, replacing four separate products. Go to Green Star

New on the shelf: the INNOVACAR Micron microfibre range covers drying, polishing and interior with dedicated cloths. See new arrivals

Direct advice: send us a photo of your steering wheel and we will tell you whether cleaning is enough or a colour system is needed. Start a chat

  • Automotive interior care at a pro level: THE FINISHER × Koch-Chemie

    THE FINISHER × Koch-Chemie gives you a clearly structured, perfectly matched interior-care system for plastic, leather, textile, glass and displays – for clean, well-kept, material-safe results without any guesswork.


    The interior of your car needs products that work clean, safe and material-friendly. That's exactly what AUTOMOTIVE — THE FINISHER × Koch-Chemie Interieur was built for: a curated interior line that pairs Koch-Chemie technology with an intuitive, mistake-proof workflow. You clean, care for and protect leather, textile, glass, displays and plastics in a clear order – cleaning first, then care, kept separate by material. The result: fresh surfaces, a pleasant feel and crystal-clear visibility with no streaks.

    • Clear interior system: Cleaning and care are split logically – each surface gets exactly the right product.
    • Material-safe results: Plastics stay matte, leather stays supple, textile gets protected, glass and displays stay completely streak-free.
    • Fast, safe workflow: The products work into each other and stop the classic mistakes – stains, streaks, over-conditioning or dull surfaces.

    Interior cleaning – clean, gentle, no residue

    The first step inside is always a thorough, material-safe clean. InsideUp is your all-rounder for hard plastics and pulls deep-down dirt out of the pores with no shiny patches or greasy residue. For leather and textile areas you reach for LeatherTexClean, which works gently but effectively, doesn't dry the surfaces out and won't rough up the fibres. Sensitive kit like touchscreens, nav displays or piano-black trim is handled by DisplayExpert, with a fast-flashing formula that works without alcohol streaks or smearing. Together these cleaners make sure every surface is genuinely free of dirt, skin oils and build-up – the perfect base for the care products that follow.

    Care & protection – natural look, pleasant feel, lasting effect

    Once it's clean, you lock in the material's look and give the surfaces protection. InsideCare handles interior plastics: not greasy, not glossy, just a natural matte with UV protection and a nice feel in the hand. On leather, LeatherLock builds a supple protective layer that conditions the material, darkens it slightly and guards against premature ageing – with zero greasy film. Textile surfaces like seats, headliner or floor mats you lock down with TexLock: a high-performance textile sealant with an easy-to-clean effect that makes it harder for liquids to soak in, cuts down odours and makes everyday cleaning far easier. With this matched care chain your interior keeps its clean, high-quality look without any artificial over-conditioning.

    Glass & viewing surfaces – maximum clarity, no streaks

    For clear vision and a high-end finish up front, ClearView does the job. The glass cleaner is highly volatile, streak-free and formulated to nail perfect results even on tricky, modern glass. Inside the car especially – where fingerprints, off-gassing and smeary films show up – ClearView shows its strength: the surface stays bright, dry and residue-free, even with the sun low or in backlight. Together with DisplayExpert you get a complete visibility system that safely covers both classic glass and modern displays.
