Rinsing & Storing Your Regulator
You should rinse your regulator and gauges with fresh water at the end of each diving day. It's recommended you soak the regulator overnight to dissolve all salt crystals, followed by a fresh water rinse before storage.

When rinsing the regulator you must take special precautions to prevent water from entering the hoses and 1st stage. Make sure the dust cap is installed before immersing the regulator in water. The dust cap seals against the 1st stage's air inlet and protects the regulator from water and dirt. Also, never press the purge button when rinsing the regulator. Doing so allows water to enter the air hose and eventually the 1st stage.

Store the regulator carefully to avoid damaging the hoses. Tight coils and kinks stress the hoses and cause cracking.
