Get an ear bulb (looks like a small turkey baster) to blast rinse water thru the drain holes on your first stage to remove the salt. This is very important on liveaboards where your reg stays setup on the tank for a week or more! I keep mine in the mask box to remind me :)
When rinsing regs having them turned on and on a tank works better, having a pony bottle to do this with is easier on the back.
If after the dive it’s a communal rinse tank (that probably only has the water changed once a day) then my gear gets another rinse when I get home. The wet suite (suit, gloves, boots, hood) get laundry soap or shampoo. Do not leave your gear to dry in the direct sun.
Hang the wet suit to dry but store the wet suit flat, do not lay anything on top of it! I use old hair curlers, obviously not mine to hold gloves and boots open to dry.
