Why Buy Sea-It

Sea-It Features

Readily Biodegradable

Unlike some other brands Sea-It do not use phosphates, nitrates or detergents that take years biodegrade and are harmful to the environment.
Our detergents breakdown with in 28 days.


Sea-It Wash is safe for the whole family, with no toxins or dangerous chemicals it is safe to use.

New Zealand Owned

Sea-It is New Zealand owned and operated here in Auckland, New Zealand.

Repels Dirt, Grime & Salt

Sea-It Marine Wash creates a film over what it is sprayed on to which helps resist salt, dirt and dust from sticking to your boat, car or trailer.

What it is

Sea-it is an environmentally responsible cleaner, salt remover and surface protectant for all areas where surfaces and equipment are dirty, soiled, been in contact with salt water, salt air, mud, dirt, grime or soiling. The protectant polymer fills small gaps in materials allowing water to sheet off.

Sea-it is manufactured using *readily biodegradable* surfactants and chelating agents along with a protective polymer, to reduce the ability of salt, dirt and oil to re-adhere to surfaces that have been cleaned with Sea-it. Readily biodegradable meets a more stringent test than normal biodegradable. See definition below.

*Readily Biodegradable is a term used for substances that meet the very stringent testing criteria of a ready biodegradability test demonstrating ultimate biodegradation within a specified time period usually 15 – 28 days.

Biodegradable product has the ability at some stage in time to break down, safely by biological means into the environment. This could be days, weeks, months or years.

Chelating Agents

The agent used in Sea-it is a new generation, sustainable and very readily biodegradable. This is from natural and renewable sources unlike other products which use phosphates to tie up metals and ions within the formulation and when the chemical is used.


The surfactants used in Sea-it are at the cutting edge of sustainable and readily biodegradable chemistry. Excellent at cleaning and removing soil and salt from all hard surfaces.


The polymer used in Sea-it is a “smart generation” polymer designed to impart cleaning with a surface protectant and soil resistance which has excellent releasing properties to treated surfaces. Treated surfaces repel soap-film, salt, dirt, soil, grime and even bathroom grim by creating a highly effective invisible soil barrier. The polymer will fill any unevenness in the surface which dirt normally sticks to.

How Sea-it works

Once the heavy gross soil is removed, clean with Sea-it using your normal method of cleaning. Once the solution has gone onto the surface the polymer fills any small areas, cracks or crevices and creates a smooth surface reducing the ability of dirt to adhere to the surface. Sea-it is an excellent cleaner.

Rinse off as normal, leaving a shiny clean surface which will reduce over time the need to engage in heavy cleaning.
