Mold and mildew are an ongoing problem for boaters. Unsightly and smelly, they are the natural result when a damp environment combines with limited airflow–such as in the confines of a boat. Unfortunately, there are countless surfaces in your boat that can be affected and, like rabbits, the reproductive power of these fungi is astonishing. Ignore a small spot, and you may soon find you've been overtaken.

Good ventilation is of primary importance, followed quickly by the need to keep everything clean and dry to reduce humidity. But no matter how careful you are, how many preventative measures you take, sometimes it isn't enough.

If you spot mold or mildew, place the affected item in the sun where UV rays will kill it and stop if from spreading. Open all the curtains to let as much light into the cabin as possible. Of course, since virtually everything on a boat -- save metal -- is subject to this creeping crud, much of it bolted down and far distant from the sun's rays, the technique is not exactly a universal cure.

That's where chemical treatments come in. It's a good idea to start with the mildest solutions first: non-detergent or phosphate-free soap and water, a paste of lemon juice and salt or a white-vinegar and salt solution, bathroom cleaners and various protectants.

If these don't work, it's on to the big boys: Bleach or commercial mildew removers. Be sure to use rubber gloves and eye protection when scrubbing, then rinse and dry thoroughly. To make a bleach solution with extra punch, add two-thirds of a cup tri-sodium phosphate, or TSP, to 1 quart of bleach and four quarts of water. Be advised that some bleach and bleach solutions may weaken fabrics. Try the solution on a small, unobtrusive area before using it on a treasured surface.
