Boats can be notorious breeding grounds for many different kinds of smells, and when you’re out on the open water you don’t suddenly want to find yourself wishing you’d paid more attention to boat odor removal. In addition to being completely surrounded by water (aka moisture, a necessity for odor-producing microorganisms), you’re also essentially shrinking everything you do in a house down to just a few square feet.

Some of the more common sources of odors in boats include:

The Bilge

Everything eventually ends up in the bilge, and with no airflow, the resulting mix produces a slow, and unpleasant, bilge scent.

The Head

Odors here can come from the toilet, holding tank, leaky hoses, sink traps…basically anything associated with the head. Even the gray water tank can build up stale grease smells over time as it accumulates oils and other body residue.

The Galley

Your mini kitchen on the sea, with all its associated odors. This includes everything from cooking odors and trash containers to the refrigerator and microwave vents.


Much like your house, mold can be a big problem, both smell-wise and health-wise. Mold can accumulate during voyages, or even while your boat is in storage.

The Engine

When the engine heats up, any petroleum products that have been accidentally spilled on it will start to cook off. The smell of raw diesel could also signal a fuel leak.


If you’ve got a boat, you’re probably fishing, and fish are notorious odor producers. Any place you keep fish, or any place that fish have even touched, will have a lingering fish smell.

The Anchor and Chain

Even the chain/anchor and the chain locker where it is stored can be a significant source of odor. The chain and anchor are constantly bringing up material from the sea bed, which, if not properly cleaned out, can accumulate and rot.

Closure Clean can help you to effectively eliminate all these odors associated with your boat. With the power of chlorine dioxide at your disposal, you can remove these odors permanently, leaving just the refreshing scent of the sea.
