When rinsing a regulator, what is the recommended method?

Rinsing a regulator while it is still attached to the tank is considered the recommended method because it allows the diver to control airflow through the regulator during the rinsing process. This is particularly important as it helps to ensure that any contaminants or saltwater are effectively flushed out of the mouthpiece and the first and second stages of the regulator. Additionally, leaving the regulator attached allows for the low-pressure side to be rinsed out effectively since it helps maintain the regulator’s structure and prevents any foreign particles from entering its internal components.

Using warm water to soak the regulator might seem like a good idea for cleaning, but prolonged exposure can potentially harm the internal components and materials, especially for any electronic or rubber parts. Employing a high-pressure hose can be too forceful and might risk damaging sensitive components inside the regulator. Removing the regulator and brushing it may not provide thorough cleaning without first controlling airflow or risking damage to detachable parts. Hence, rinsing while the regulator is attached to the tank combines safety and efficiency in the cleaning process.
