Superyacht Exterior Washing Using Deionised Water

Eco friendly yacht washing support

Marine Tech Wash, a specialist division of Marine Surfaces, provides professional superyacht exterior cleaning using purified water technology.

Our mobile, trailer-mounted water purification system produces deionised water with a total dissolved solids (TDS) reading of approximately 0–20 ppm, reducing the minerals and dissolved salts present in ordinary water.

This enables effective exterior cleaning and rinsing while helping minimise mineral deposits and water spotting.

Our service is particularly valuable for yachts without onboard purified-water washing systems, as well as vessels requiring additional cleaning support during busy yard, yacht show & pre- sales periods.

Zero Soap. Zero Chemicals.

Our pure deionised water system uses absolutely no soaps, detergents or chemical agents — delivering a flawless, streak-free finish while keeping harmful substances out of our seas.

Our Superyacht Exterior Washing Services

Deionised Water Yacht Washing

Our purified water washing system helps remove salt deposits, surface dirt and general contamination from yacht exteriors. By using low-mineral water, we can reduce reliance on conventional cleaning chemicals for suitable routine washing applications.

Superyacht Hull & Superstructure Cleaning

We provide controlled exterior cleaning of painted hulls, superstructures and other suitable marine surfaces. Our team uses carefully selected soft brushes and cleaning equipment, with procedures adapted to the condition and specification of each surface.

Heated Purified Water Cleaning

For appropriate applications, our system can heat purified water to approximately 60°C, helping loosen stubborn salt deposits and contamination in difficult-to-access areas. Water temperature and cleaning methods are selected according to the surface and coating manufacturer's requirements.

Soft Wash Foam Treatment

Where ordinary purified water washing is insufficient, we can incorporate suitable soft wash foam treatments to assist with heavier contamination.

Yacht Show, Refit & Charter Cleaning Support

Our mobile service can support yacht crews during pre-charter and post-charter preparations, yacht shows and exhibition periods, shipyard refits and maintenance programmes, intensive operational and charter seasons, and exterior washing before inspections or guest arrivals.

Experienced Superyacht Exterior Cleaning Teams

Our technicians understand the logistical challenges of washing large yachts, including access from tenders, floating platforms and onboard working areas. We plan each project around the yacht's location, operational schedule and surface requirements.

Post-Refit Wash Down — 2 Years Under Scaffold

This yacht had been enclosed under a scaffold and tent for two years during a full refit. Our team carried out a complete pure water wash down of the entire vessel — topsides, superstructure and glass — removing two years of accumulated dust, residue and construction fallout with zero chemicals used throughout.

Pure Water Hull Washing — Superyacht Techwash

Our pure water hull washing system delivers a streak-free, spot-free finish on superyacht topsides, superstructure and glass — without chemicals or abrasives. We operate Baudoin carbon fibre poles with soft brush and sponge heads designed specifically for superyacht paint, giving us a reach of up to 21m to clean the full height of even the largest vessels safely and without contact damage.
