Koch Chemie The Finisher DisplayExpert: Screen & Gloss-Surface Cleaner

Koch Chemie DisplayExpert: The Screen Cleaner Built For Modern Vehicles

Koch Chemie DisplayExpert is the dedicated screen and gloss-surface cleaner from the Koch Chemie The Finisher line, engineered specifically for the infotainment displays, head-up panels, digital instrument clusters and piano black trim that define modern vehicle interiors. Developed in the Koch Chemie laboratories in Unna, Germany, DisplayExpert is alcohol-free, ammonia-free and formulated to clean delicate touchscreens without affecting the oleophobic coatings that prevent fingerprint adhesion.

Where regular glass cleaners contain ammonia or solvents that degrade touchscreen coatings over time, DisplayExpert respects the surface treatments OEMs apply to modern displays. The German formulation dries to a streak-free, anti-static finish that resists future fingerprint accumulation, extending the time between cleanings. The compact 100ml bottle is sized to fit in the door pocket or glove box for on-demand screen care.

Why Detailers Trust DisplayExpert

• Screen-safe chemistry: alcohol-free and ammonia-free, formulated specifically for touchscreens and oleophobic coatings.
• Streak-free finish: evaporates clean with no haze, residue or film that would affect display brightness or visibility.
• Anti-static surface: the treated surface attracts less dust and fingerprints than untreated screens.
• Piano black safe: works on the high-gloss interior trim that scratches and shows fingerprints in any other cleaning method.
• Pocket-sized: compact 100ml bottle fits in door pockets, glove boxes and centre console compartments for on-demand use.
• Made in Germany: formulated and bottled in Koch Chemie's own laboratories in Unna.

How to Use Koch Chemie DisplayExpert

1. Turn off the screen or display before cleaning. A dark surface makes contamination visible and prevents heat-related streaking.
2. Spray DisplayExpert directly onto a clean microfiber towel, never onto the screen itself. Direct spray can drip into bezels and reach electronics.
3. Fold the microfiber towel into quarters for four clean working surfaces.
4. Wipe the screen gently in straight passes, starting from one corner and working across in slightly overlapping passes.
5. Flip the towel to a fresh quarter for the second pass in the opposite direction. This two-direction wiping ensures complete coverage.
6. Inspect under angled light to verify a streak-free finish. Re-apply only if needed.

Pro tip: for daily fingerprint cleaning a single spray on a clean cloth is enough. Heavy contamination such as food residue or oily fingerprints may benefit from a second pass. Avoid pressure when wiping touchscreens to prevent triggering touch input or applying force that could affect calibration over time.

Important: never spray DisplayExpert directly onto a screen. Liquid intrusion past the bezel can damage display electronics. Always spray onto the towel first.

Frequently Asked Questions

Can I use regular glass cleaner on my car infotainment screen?
No, not safely. Regular glass cleaners contain ammonia or alcohol that degrade the oleophobic coatings on modern touchscreens over time. The coatings prevent fingerprints from sticking. Once degraded, the screen becomes a fingerprint magnet. DisplayExpert is specifically formulated to clean without affecting these coatings.

Is DisplayExpert safe on piano black interior trim?
Yes. Piano black trim shows every fingerprint and scratch, and most cleaning methods cause hairline scratches that show up under angled light. DisplayExpert combined with a high-quality microfiber towel cleans piano black without adding scratches. Always use very light pressure on glossy plastic.

Can DisplayExpert be used on a phone or tablet screen?
Yes. The same formula works on smartphone screens, tablet screens and laptop displays. For phones with anti-glare or matte coatings, test on a hidden corner first to verify compatibility.

Why is DisplayExpert only 100ml?
The 100ml bottle is sized specifically for storage in door pockets, glove boxes and centre console compartments so it is available whenever a screen needs quick cleaning. For shop or studio use, the small format may seem limited, but for the end user it is the right size for the application.

Will DisplayExpert remove sticky residue from a screen?
For light residue such as sunscreen or hand cream, yes. For sticky food residue or adhesive marks, the formula may not be aggressive enough. Apply DisplayExpert, let it dwell for 30 seconds and then wipe gently. For heavier contamination, multiple applications may be needed.

Where is DisplayExpert made?
Koch Chemie DisplayExpert 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.
