Drysuit Corrosion Prevention
Protecting your drysuit from corrosion is essential for any diver who values the longevity and reliability of their gear, especially as the weather warms and dive adventures beckon. Exposure to saltwater, grit, and even the humid air found near the coast can accelerate the breakdown of metal components like zippers and valves, as well as degrade delicate latex and neoprene seals. Whether you’re gearing up for a summer of local lake dives or planning a trip to colder northern waters, incorporating corrosion prevention into your regular maintenance routine will help ensure your drysuit performs at its best. Divers who log frequent hours underwater, instructors guiding students in open water, and even those who enjoy the occasional weekend dive all benefit from proactive care. In fact, corrosion prevention products make thoughtful gifts for dive buddies, club members, or anyone receiving a new drysuit—especially as a practical addition to a gear bag at the start of the season.
Routine rinsing with fresh water is the cornerstone of corrosion prevention, but the details matter. After each dive, it’s important to flush both the inside and outside of your suit, with special attention paid to metal zippers and exhaust valves where salt and sand love to hide. Gently brushing away debris from zipper teeth before opening or closing helps prevent damage and ensures smooth operation. Once clean, allow the suit to dry thoroughly—inside and out—to ward off mold, mildew, and the moisture that can fuel internal corrosion. Latex seals should be lightly dusted with unscented talc or treated with UV protectants to keep them supple and prevent sticking or premature aging, while avoiding contact with chemicals like sunscreen or insect repellent that can accelerate deterioration. For storage, always follow manufacturer guidelines: brass zippers are best stored open to relieve stress on the teeth, while plastic zippers should be kept closed. Hanging your suit on a sturdy, specialized hanger in a cool, dry, and shaded place—away from direct sunlight and electrical equipment—will help preserve materials and prevent ozone damage, a common culprit in latex failure.
