Scuba diving gear is expensive, proper cleaning and routine maintenance can make it last longer. Keeping your gear properly clean and maintained after scuba diving will reduce the chance of equipment failure. 

Regulator: 

Before rinsing your regulator, blast air into the dust cap and secure it on the first stage. Submerge the regulator in freshwater and move the second stage and alternative regulator around, dissolving and removing the salt residue. Allow the regulator to dry before storing it. 

Wetsuits, booties, hoods, rash guards and gloves:

Salt water causes neoprene in wetsuits to degrade and become rigid. Soaking in warm water allows the salt particles to dissolve and removes debris. You may want to use a wetsuit cleaner, but make sure it is designed for neoprene as some chemicals degrade the material. Submerge it in warm water, massage, open all zippers, rinse and hang wetsuits inside out to avoid sun exposure. Store in a well-ventilated area but not in direct sunlight, the material needs to dry completely to avoid mold and bacteria growing. Make sure to use a wetsuit hanger to avoid stretching the neck of the wetsuit. Once everything is dry, you can pack it away and store it. 

Mask, Snorkel, and Fins:

Rinse your mask, snorkel and fins in freshwater. Most dive centers will have separate buckets for delicate items: those related to your face and other items. Allow them to dry before storing them, do not leave them in direct sunlight for extended periods as in hot climates the silicone or rubber can disintegrate. Store your mask in its box to avoid scratches. 

Computer: 

Thoroughly wash your computer and press all the buttons while it’s submerged in freshwater after diving. This will remove the salt and sand particles and prevent build-up. 

Buoyancy Control Device: 

BCDs need to be cleaned on both the inside and outside. During a dive, salt water leaks into the BCD through the dump valves and low-pressure inflator. Drain your BCD after the dive. Rinse your jacket with freshwater, use a hose to flush water into your jacket by holding the deflate button and allowing water to run into the low-pressure inflator. Fill with air and shake the jacket ensuring the water inside of the jacket circulates removing the salt. Invert the jacket, squeeze and drain the fresh water from the BCD with the LPI deflate button or dump valves. Repeat the process several times before leaving the BCD partially inflated to dry. Store your BCD in a warm and dry place.
