Koch-Chemie × THE FINISHER THE FINISHER "InsideUp" Interior Cleaner 500ml

THE FINISHER × Koch-Chemie „InsideUp“ — Interior Cleaner for Clean Surfaces in the Interior

How does InsideUp work in everyday life? — The ready-to-use interior cleaner gently dissolves skin oils, dust, drink residue and nicotine film from plastic, leather, textile and vinyl, dries streak-free and creates the perfect basis for subsequent care on road and sea.

THE FINISHER InsideUp Interior Cleaner is your universal cleaner for dashboards, seats, door panels, and cabins. The balanced surfactant formula encapsulates dirt, safely removes everyday films, and leaves a clean, grippy surface without smearing. In automotive interiors, it works quickly and leaves no residue; in marine applications, it reliably removes salt film and sunscreen residue. As a system product, it is the ideal foundation before you care for and protect surfaces with InsideCare, LeatherLock, TexLock, or VinylGuard.

• Efficient Deep Cleaning: Encapsulates fats and particles, reduces friction during wiping and thus minimizes roughening or shiny spots on soft-touch plastics.
• Gentle & Controlled: pH-balanced, short flash-off time, clean drying – ideal for mixed materials in the interior (plastic, leather, textile, vinyl).
• Perfect System Base: After cleaning, polishes and sealants adhere noticeably better; compatible with InsideCare, LeatherLock, TexLock, VinylGuard and the sensitive DisplayExpert for screens.

Interior Cleaner – Technology & Material Compatibility

Interior cleaners like THE FINISHER InsideUp work with a finely tuned balance of surfactants and solvents: fats, sugars, and dust are bound in micelles so that you can safely pick them up with a microfiber cloth instead of smearing them. The formula is pH-balanced for everyday use and can be applied to typical vehicle and cabin materials – from textured plastic to coated leather, textile, and marine vinyl. Clean soft-touch surfaces with minimal pressure; treat displays separately with DisplayExpert. For stubborn stains on leather/textile, please specifically tackle them with LeatherTexClean; on vinyl/textile in a marine context, VinylTexClean shows its strengths. THE FINISHER InsideUp Interior Cleaner deliberately leaves no residue, so that care products can absorb evenly afterwards.

Automotive – Structured Application in the Vehicle Interior

Automotive means many material changes in a small space. Work component by component: spray the product onto the cloth, or sparingly onto the surface for heavier soiling, let it dissolve briefly, lift it into structures with a soft brush, and remove it with a fresh microfiber side. THE FINISHER InsideUp Interior Cleaner prevents streaking and ensures a natural, non-greasy feel. After cleaning, secure the result appropriately: plastics with InsideCare, smooth leather with LeatherLock, textile surfaces with TexLock. For touchscreens, piano black inserts, and infotainment: do not wipe with all-purpose cloths, but specifically use DisplayExpert to avoid micro-scratches and streaks. This keeps the interior visually calm and tangibly clean.

Marine – Confidently Clean Cabin, Cockpit & Vinyl

Marine surfaces are constantly exposed to salt, UV, and sunscreen. THE FINISHER InsideUp Interior Cleaner removes the typical salt film on consoles and panels and dissolves lotion residues on upholstery without drying out vinyl. Never work in direct sunlight and do not let the cleaner dry; after a short dissolving time, wipe with a damp cloth and dry with a second cloth. On vinyl upholstery, you get a clean, grippy finish – ideal as preparation for VinylGuard. You can clean textiles on board with InsideUp before stabilizing their easy-to-clean properties with CoverGuard or TexLock. For windows and polycarbonate, use SeaYou; for unpainted plastics, RubMarine will make them look good again after cleaning.

Frequently Asked Questions about THE FINISHER × Koch-Chemie „InsideUp“ — Interior Cleaner

Can I use InsideUp on leather?

Yes, on coated/sealed leather. Always test in an inconspicuous area. For stubborn stains, LeatherTexClean helps; then care with LeatherLock to stabilize the feel and color depth.

Work section by section: spray onto a cloth, let it dissolve briefly, move with a brush/cloth and remove with a clean side. Do not let it dry, do not over-treat, finally wipe dry.

Is InsideUp suitable for displays?

For sensitive screens, please use DisplayExpert. InsideUp is optimized for plastics, leather, textiles and vinyl and works streak-free and material-friendly there.

Does InsideUp also work in boats?

Yes. It removes salt film and sunscreen residues in the cockpit and cabin. Afterwards, apply VinylGuard or InsideCare to facilitate cleaning and protect surfaces from quick re-soiling.
