Koch Chemie The Finisher InsideUp: All-Purpose Interior Cleaner

Koch Chemie InsideUp: The Interior Cleaner That Lifts Without Stripping

Koch Chemie InsideUp is the all-purpose interior cleaner from the Koch Chemie The Finisher line, engineered to lift dirt, body oils, fingerprints and ground-in grime from car interior plastics, fabrics and vinyl without leaving streaks, residue or chemical odour. Developed in the Koch Chemie laboratories in Unna, Germany, InsideUp uses a balanced surfactant blend tuned for the variety of materials inside a modern vehicle: hard plastic, soft-touch dashboards, vinyl door cards, fabric upholstery and headliner.

Where multi-purpose household cleaners often leave residue that attracts dust or strip the protective coatings on dashboard plastics, InsideUp dries clean and respects the surface treatments your interior was finished with at the factory. The German formulation works as a ready-to-use spray for routine cleaning and dilutes up to 1:4 with water for lighter maintenance work. Pair with InsideCare for a complete clean-and-protect interior workflow.

• Dilutable formula: ready to use straight from the bottle or dilute up to 1:4 with water for light maintenance cleaning.
• Pleasant fresh scent: no chemical or solvent smell lingering after cleaning.
• Made in Germany: formulated and bottled in Koch Chemie's own laboratories in Unna.

How to Use Koch Chemie InsideUp

1. Vacuum the interior thoroughly to remove loose dust, crumbs and debris.
2. For delicate surfaces (screens, piano black, perforated leather): spray InsideUp onto a clean microfiber towel first, not directly on the surface.
3. For sturdier surfaces (vinyl, hard plastic, fabric): spray InsideUp directly onto the surface from a few inches away.
4. Work the product in gently with a microfiber towel or soft brush for fabric, using straight passes on smooth surfaces.
5. For embedded dirt in seams or stitching, agitate with a soft detailing brush.
6. Wipe clean with a fresh microfiber towel. No rinsing required.

Dilution recommendations: use at full strength for heavy contamination, 1:1 for moderate cleaning, 1:4 for light dust and fingerprints. The diluted ratios are more economical and equally effective for routine maintenance.

Pro tip: always test on a hidden area first when treating Alcantara, perforated leather or printed fabrics. For complete interior detailing, follow with InsideCare on plastic surfaces and LeatherLock on leather to add UV protection and resistance to future contamination.

Frequently Asked Questions

What is the difference between InsideUp and InsideCare?
InsideUp is the cleaner. InsideCare is the dressing and protectant. The two products work together as a complete interior workflow: InsideUp first to clean the surface, InsideCare second to dress and protect the cleaned surface. Using only the cleaner leaves the surface unprotected. Using only the dressing traps contamination underneath.

Can I use InsideUp on leather?
Yes for routine cleaning. For deep leather cleaning use LeatherTexClean, which is specifically pH-balanced for leather. For general dust removal and fingerprint cleaning on leather, InsideUp works well at diluted strength.

Will InsideUp leave streaks on glossy dashboard plastic?
No. InsideUp is formulated to evaporate residue-free, so it leaves no streaks or shine-killing film on glossy plastic. For best results on piano black trim, spray onto the microfiber towel first and wipe gently to avoid pooling product.

Can I dilute InsideUp?
Yes. For light cleaning dilute 1:4 with water. For moderate cleaning 1:1. Use at full strength only for heavy grease, food spills or ground-in dirt. Dilution makes the bottle last significantly longer for routine maintenance work.

Is InsideUp safe on Alcantara?
Yes when used carefully. Spray InsideUp onto a microfiber towel first (never directly on Alcantara) and dab the surface gently. After cleaning, brush the Alcantara nap with a soft brush to restore the texture. For heavily soiled Alcantara consider a dedicated fabric extractor approach instead.

Where is InsideUp made?
Koch Chemie InsideUp 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.
