When you are finished using your scuba equipment, it is necessary to disassemble it for rinsing and storage. Cleaning your gear after each dive will not only extend the life of your gear but give you an opportunity to check for any problems. Once you create a cleaning routine it will become second nature to you.

There are three general maintenance procedures used in caring for all diving equipment: 1)rinse thoroughly with fresh water after each use, 2)keep out of direct sunlight and 3)store in a cool, dry place. A Freshwater rinse will eliminate contaminants and corrosion. After you have used your equipment in salt water, it should be soaked for several minutes in warm, fresh water to prevent the buildup of damaging slat crystals. Because the sun's rays can damage neoprene and silicone products, avoid leaving your equipment in direct sunlight. Dry your equipment thoroughly before storing it. In addition, masks and other equipment composed of silicone should be stored away from black rubber products to prevent staining of the silicone.

I have provided some basic maintenance information below. These are only guidelines be sure to check with the equipment manufacturer for the exact maintenance required for your gear.

Mask, Fins and Snorkel	All should be rinsed in fresh water after use, stored in a cool, dry place away from direct sunlight.
Regulators	Should be rinsed, but it's usually best to soak it first, then rinse with running water. Be sure the dust cover is in place to keep water out of the first stage. Make sure the unit is professionally serviced once a year.
BCD	In addition to rinsing, drying and storing out of sunlight, your BCD has two additional maintenance considerations. The inside of the BCD must be rinsed with fresh water.(Fill it about one third with water through the inflator hose. then inflate the rest with air. Swish the water around inside, then drain completely through the hose.) Store your BCD partially inflated.
Exposure Suit	Rinse. Dry inside out. Store without fold on a wide non-metal hanger out of direct sunlight. Lubricate zippers and fasteners with silicon spray or some other non-petroleum lubricant.
Weight Systems	Require little maintenance. Careful handling is important to avoid damage to equipment and accidental injury.
Computers	Rinse with fresh water. If storing for a long period of time, some require the battery be removed. Check with the manufacturer.
Lights	Rinse with fresh water. Store without batteries to prevent battery leakage. Follow the manufacturers instructions for disassembling the unit for cleaning. I usually give it a complete cleaning after 4 dives.
Knives	Although diving knives are made of stainless steel, they will rust. Rinse in fresh water after use. Sharpen occasionally according to manufacturers instructions.
