Pure Water Hull Washing for Superyachts
Deionised Pure Water Cleaning for Hulls, Superstructures and Glass
Marine Techwash, a specialist division of Marine Surfaces, provides pure water cleaning services using deionised water to deliver a spotless, residue-free finish on superyacht hulls, superstructures and glass.
Pure water cleaning eliminates the mineral deposits and streaking associated with conventional washing, leaving surfaces clean without the need for detergents or chemical additives.
Our approach supports long-term surface care by reducing contamination build-up and minimising the risk of staining or damage to painted and polished surfaces.
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. It's the most environmentally responsible way to wash a superyacht.

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.

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.
