Salt is a ubiquitous and inevitable presence in marine environments. While it is essential for the survival of many marine organisms, it can be detrimental to boats and other marine equipment. Salt buildup can cause corrosion, clog up water intakes, and damage engines, electronics, and other equipment. That’s why it’s crucial to remove salt from your boat and marine gear regularly. But which product should you use between Salt Away vs. Salt Off? In this article, we’ll compare these two salt eliminators and help you decide which one is the best for your needs.
What is Salt Away?
Salt Away is a popular salt remover that claims to be biodegradable, non-toxic, and safe for use on all surfaces. It is a concentrate that you mix with water to create a salt-removing solution. Salt Away is available in different sizes, from a 16-ounce spray bottle to a 55-gallon drum, depending on your needs.
Salt Away’s formula includes a surfactant, which helps the solution penetrate and dissolve salt deposits, and a corrosion inhibitor, which helps protect metal surfaces from further damage. Salt Away also claims to be effective at removing other types of contaminants, such as dirt, grime, and algae.

What is Salt Off?
Salt Off is another salt eliminator that claims to be biodegradable, non-toxic, and safe for use on all surfaces. It comes in a ready-to-use spray bottle or a concentrate that you mix with water. Salt Off is also available in different sizes, from a 22-ounce spray bottle to a 55-gallon drum.
