One of the greenest things you can do to treat odors is to keep them from developing in the first place.

Plenty of fresh air and sunshine are Nature's most effective deodorizers.

Unfortunately a boat's interior is often lacking both.

Sealed up tight, with moisture all around, your boat's cabin is a perfect breeding ground for odor causing mold and mildew.

Instead of using toxic cleaners and sprays to attack this nasty stuff, why not prevent it from gaining a foothold in the first place?

Creating a simple path for air to circulate in and out of your boat is one of the most effective ways to keep mold and mildew from developing.

When installed properly these simple clam shell vents will help move plenty of fresh air through your vessel.
