Koch-Chemie × THE FINISHER THE FINISHER "CleanMarine" Boat Shampoo 1000ml

THE FINISHER × Koch-Chemie "CleanMarine" — boat shampoo for salt-free, slick surfaces

What does CleanMarine do on board? — This pH-balanced boat shampoo lifts salt and harbour film safely, builds a slick wash film, rinses clean and keeps your existing protection intact. For gelcoat, painted surfaces and smooth plastics – fast, controlled, barely a streak.

THE FINISHER CleanMarine boat shampoo is the no-fuss main wash for smooth gelcoat and high-gloss painted surfaces. The surfactant base wraps up salt, spray and organic residue while slip additives cut friction right through the contact pass. So you wash safer, rinse clean and keep your existing wax or spray sealant. Ideal after a quick pre-clean (AllWays) and before a hydrophobic finish with BodyGuard – for a surface that visibly stays fresh longer.

• Salt & spray handled: Wraps up residue and rinses it away clean – fewer water spots, a calmer finish.
• Serious slip: Cuts friction while you brush or wash and helps you dodge micro-marring – especially on dark, smooth panels.
• LSP-friendly: Keeps your wax and spray protection instead of stripping it; the perfect base for BodyGuard as a season topper.

Boat shampoo – salt film, foam stability & slip additives

A boat shampoo like CleanMarine pairs an efficient but material-friendly surfactant formula with controlled foam. Salt crystals and harbour film get locked into micelles, so you rinse them off without leaving a haze. The wash film stays slick for ages, pulls dirt out of pores and edges and lets your wash mitt or soft deck brush glide safely. Because the formula is pH-balanced, the gloss and hydrophobics of any existing wax or spray layer stay put – the result reads calm, clean and genuinely smooth to the touch.

Using it on board – pre-wet, wash, rinse

Application starts in the shade on cool surfaces. Pre-wet with fresh water first, until salt and loose grit run off. Dose CleanMarine as directed, foam it up in the bucket and work top-to-bottom in sections. Move a soft brush crossways over non-skid zones, and take smooth gelcoat or painted areas with the wash mitt in long strokes, no pressure. Don't let the shampoo flash off, rinse generously and either towel down with a clean cloth or let it sheet off. Finish the show surfaces with SeaYou afterwards; clean and treat vinyl/textile separately.

Compatibility & care plan – gelcoat, non-skid, layered protection

Compatibility covers smooth gelcoat, high-gloss marine-painted panels and smooth plastics. Non-skid gets cleaned safely without smoothing out its grip. Test matte or rough specialist surfaces first and work them without pressure. For the season logic: pre-clean (AllWays) → CleanMarine as the main wash → optionally PerfectOne/WaxPolish for visual depth → BodyGuard as a hydrophobic, quick-to-refresh finish. That way the surface stays cleaner longer, rinsing gets easier and the routine stays repeatable – even under strong sun and heavy salt.

Common questions about THE FINISHER × Koch-Chemie "CleanMarine" — boat shampoo

Does CleanMarine attack existing wax?

No. The pH-balanced formula is LSP-friendly and keeps your wax and spray protection. You can top up the beading after the wash with BodyGuard.

Is it safe on non-skid?

Yes. Work a soft brush crossways and rinse thoroughly. The shampoo cleans without touching the grip underfoot.

How do I avoid water spots?

Wash cool in the shade, don't let it flash off, rinse generously and towel down with a clean cloth if needed. Always clear the salt first with fresh water.

Can I clean plastic windows with it?

For polycarbonate/acrylic, reach for SeaYou instead. CleanMarine is the main shampoo for hull and deck, not the window specialist.

How often should I wash?

As needed: after any spray-heavy trip, or weekly through the season. A quick fresh-water rinse between washes keeps buildup down.
