Water isn’t
Just Water
Most boat owners assume dock water is clean. It’s not. Minerals, chlorine, metals, PFAs, and microplastics are all hiding in plain sight—staining hulls, pitting stainless, and damaging finishes. Spot Zero exists to educate the marine industry on what water really is, and why purity matters.
From Contaminated to Crystal Clear
Purification isn’t magic—it’s science. Spot Zero uses a multi-stage process that transforms ordinary dock water, tap water or seawater into ultra-pure drinking and rinsing water.

Common Water Myths
Myth: Filtered water is clean enough.
Truth: Filters only trap big particles and chemicals & dissolved solids remain.
Myth: Softened water protects your boat.
Truth: Softeners just trade minerals for sodium. Contaminants stay.
Myth: You can’t taste or see most contaminants, so they don’t matter.
Truth: Invisible contaminants are the most damaging to your boat, your health, and your experience.
