When rinsing a regulator, the best practice is to

• A. Leave the regulator attached to the tank or have the dust cap in place
• B. Detach and rinse only the second stage
• C. Remove the regulator
• D. Do not rinse

Answer: (A)

Rinsing a regulator after a dive is about removing salt, minerals, and debris without letting water enter sensitive parts. The best practice is to leave the regulator attached to the tank or have the dust cap in place on the first stage. This keeps water from getting into the first stage during the rinse and protects the first stage ports, while you rinse the rest of the system with fresh water. Detaching the regulator can allow water to reach the first stage and ports more easily, which can cause corrosion or other damage and makes thorough rinsing harder. Removing the regulator or not rinsing at all leaves salt behind, which can corrode components and affect performance.
