This is one the very first skills one should learn, I will not even say during OW course, but during the first lesson of it. Still, I see differences in how people do this, even people who are skilled or quite skilled.
My rules... There are priorities, so I will number the pieces of the gear in order of importance, not necessarily in the order they must be rinsed. The rules do not apply to the current time of Covid 19 that makes things completely different:
1) regs: they must be closed with their cap on and rinsed with fresh water
NO opening the cap and letting water in
NO using air to clean the first stage
2) computer, BCD: rinsed with fresh water
NO rinsing inside big containers where many people rinse their gear (it spreads bacteria)
3) DSMB: emptied from salt water and rinsed with fresh water
4) wet suit and boots: washed with fresh water
NO rinsing together with other people's gear; better leave them as they are and wash them at home (if possible)
5) Go pro, knife, other gear
Rinsed with fresh water. For some pieces of gear say knife perhaps it's not even necessary
