Koch-Chemie × THE FINISHER THE FINISHER "SeaYou" Glass Cleaner 500ml

THE FINISHER × Koch-Chemie „SeaYou“ — Glass Cleaner for Clear Visibility On Board

Why SeaYou on the boat? — This marine-focused glass cleaner removes salt film, spray, and fingerprints streak-free, runs off controllably, and is gentle on real glass, polycarbonate, and acrylic windows – for clear visibility in the cockpit, on deck, and in the cabin.

THE FINISHER SeaYou Glass Cleaner is the clear solution for marine viewing surfaces: It quickly and streak-free removes salt and spray film, water spots, and sunscreen residue. The mildly balanced formula is suitable for boat windows made of glass as well as for polycarbonate/acrylic (e.g., sprayhood, hardtop, and cabin windows) and provides a calm, low-glare finish. Ideal after an exterior wash with CleanMarine or as a quick interim step in the harbor – for confident navigation and a clean cockpit appearance.

• Marine Performance: Removes salt and spray film streak-free, reduces glare, and ensures a smooth wipe pattern.
• Material-friendly: Designed for real glass, polycarbonate, and acrylic; controlled evaporation without streaks or smudges.
• Simple & safe: Briefly dissolve, wipe off, dry with a fresh cloth – ideal for cockpit, deck windows, and cabin windows.

Marine Glass Cleaner – Salt Film, Spray & Sunscreen Under Control

Marine glass cleaners must do more than remove everyday dust: Salt crystallizes, binds moisture, and creates light refraction; spray brings organic residues, sunscreen leaves streaky fingerprints. THE FINISHER SeaYou Glass Cleaner addresses exactly these issues: Wetting additives apply the active ingredients evenly, dissolve the layer controllably, and wipe it off without a rainbow film. This keeps the surface clear, contours crisp, and reflections appear less agitated – crucial in backlight or night navigation. Because SeaYou evaporates with little residue, it also works on larger surfaces without you constantly having to "polish after."

Application On Board – Cockpit, Hardtop & Cabin

Application is incredibly simple: work in the shade, avoid hot surfaces. Spray THE FINISHER SeaYou Glass Cleaner onto a clean, dense microfiber cloth (not directly on edges or seals), wipe the surface in straight lines, and follow with a dry, fresh side of the cloth. For stubborn water spots, let it dissolve briefly; for polycarbonate/acrylic, work with minimal pressure and "straight strokes" to avoid fine wipe marks. Briefly clean wiper blades – this keeps the wipe pattern smooth. After a routine wash with CleanMarine, SeaYou is the quick visibility check before casting off; CleanMarine, BodyGuard & Co. remain responsible for exterior paint/deck.

Compatibility & Limitations – Glass, Polycarbonate, Acrylic

Compatibility includes hardened glass, polycarbonate (e.g., Makrolon), and acrylic/Plexiglas in the cockpit and cabin. THE FINISHER SeaYou Glass Cleaner evaporates clear, without sticky residues. Avoid over-wetting seals and instruments, work panel by panel, and keep cloths clean – don't "drag along" salt and sand. Not intended as a lime remover for old, baked-on water spots; such shadows may require a gentle, material-compatible polish. For automotive glass, our line offers the dedicated ClearView – SeaYou remains the specialist for boats.

Frequently Asked Questions about THE FINISHER × Koch-Chemie „SeaYou“ — Glass Cleaner

Is SeaYou suitable for plastic windows?

Yes, for polycarbonate and acrylic on board. Work with a clean cloth, light pressure, and in straight strokes to avoid fine wipe marks.

Does SeaYou really remove salt haze streak-free?

Yes, the film dissolves controllably and evaporates with little residue. Clean, salt-free cloths and working in the shade are crucial.

Can I spray directly on the window?

In the cockpit, it's better to spray onto the cloth to avoid over-wetting edges and instruments. Outdoors on deck in calm conditions, direct spraying is possible.

Does SeaYou help against older water spots?

Light spots yes. Baked-on lime scale may require careful, material-compatible polishing. Always test in an inconspicuous area.

Can it also be used quickly in the harbor?

Absolutely. A few sprays onto the cloth, wipe in lines, dry with a fresh cloth – done. Ideal after casting off or before night navigation.
