Koch Chemie The Finisher InsideCare: Interior Dressing

Koch Chemie InsideCare: The Interior Dressing That Looks Factory

Koch Chemie InsideCare is the matte-finish interior dressing from the Koch Chemie The Finisher line, engineered to refresh and protect car interior plastics, vinyl and rubber trim without leaving a greasy shine. Developed in the Koch Chemie laboratories in Unna, Germany, InsideCare uses water-based chemistry that absorbs into the surface and dries to a natural factory look, not the wet plastic shine that defines amateur interior detailing.

Where many interior dressings leave a sticky residue that attracts dust and fingerprints, InsideCare dries clean and adds UV protection to prevent the fading and cracking that plagues dashboards over years of sun exposure. The German formulation works equally on dashboard tops, door cards, centre consoles, steering wheel hubs, plastic trim and rubber gasket faces. A single application gives weeks of refreshed appearance and ongoing protection.

Why Detailers Trust InsideCare

• Matte factory finish: dries to a natural look without the wet plastic shine that signals amateur detailing.
• UV protection: blocks the photo-degradation that fades dashboards and cracks dark plastic trim over time.
• Water-based formula: safer than solvent-based dressings for use around adhesives, screens and electronic components.
• Multi-surface: works on dashboard plastic, vinyl door cards, rubber trim, console plastics and unpainted exterior plastic.
• Anti-static behaviour: the treated surface attracts less dust than untreated plastic, extending the time between cleanings.
• Made in Germany: formulated and bottled in Koch Chemie's own laboratories in Unna.

How to Use Koch Chemie InsideCare

1. Clean the surface first with Xpress Interior Cleaner or another interior cleaner and allow to dry completely.
2. Spray InsideCare onto a clean microfiber applicator pad or directly onto the plastic surface, 2 to 3 sprays per panel section.
3. Spread the product evenly with the applicator pad using straight passes. Cover all visible surfaces evenly.
4. Let the product dwell for 1 to 2 minutes to allow absorption into the porous plastic surface.
5. Wipe any excess with a clean microfiber towel for a uniform matte finish. There should be no streaking or pooling.
6. Allow the treated surface to cure for 15 to 30 minutes before normal contact use.

Pro tip: apply InsideCare every 4 to 6 weeks on daily-driven vehicles to maintain UV protection and prevent the gradual fading that affects dark interior plastics. The treatment also makes routine dust removal easier because treated surfaces accumulate less static dust.

Important: never apply InsideCare to a steering wheel, gear knob, pedals or other touch-control surfaces. The dressing reduces grip and can create a slippery feel that affects driving safety. For touch surfaces use only a damp microfiber towel for cleaning.

Frequently Asked Questions

What is the difference between InsideCare and InsideUp?
InsideCare is the interior dressing for surfaces you do not touch regularly: dashboard, door cards, plastic trim. InsideUp is the interior cleaner for surfaces that need active cleaning. The two products work together: InsideUp for cleaning, InsideCare for dressing the cleaned surface.

Is InsideCare greasy or shiny?
No. InsideCare dries to a matte natural finish that maintains the factory look of automotive plastics. Products that leave a greasy or shiny finish are typically older silicone-based dressings. InsideCare uses modern water-based chemistry that absorbs into the surface and dries clean.

Can I use InsideCare on the steering wheel?
No. Never apply interior dressing to steering wheels, gear knobs, pedals or other grip surfaces. The treatment reduces friction and can create unsafe driving conditions. For touch surfaces use only a damp microfiber towel for cleaning.

Will InsideCare protect against cracking?
Yes, indirectly. The UV inhibitors in InsideCare slow the photo-degradation that causes dashboard plastic to fade and crack over years of sun exposure. Regular application (every 4 to 6 weeks) provides cumulative protection that significantly extends the useful life of dark interior plastics.

Can I use InsideCare on exterior plastic trim?
Yes. InsideCare works on unpainted exterior plastic trim such as bumper panels, mirror housings and trim mouldings. The matte finish and UV protection are particularly valuable for exterior trim, which is exposed to direct sunlight much more than interior plastic.

Where is InsideCare made?
Koch Chemie InsideCare is formulated and bottled in Germany by Koch Chemie GmbH at their headquarters in Unna. The Rag Company Europe is an authorised dealer of the Koch Chemie The Finisher line for Europe.
