I do it slightly differently than RPR. I'll dump the black tank, normally. Then I'll close the Black Tank Valve and run the sprayer for several minutes. Like three minutes.
After that, I'll re-open the Black Tank valve and let the contents drain. I'll often repeat this once or twice more, until I see the water coming out is clear(ish). I have a clear sewer hose connection near the end, so I can see the color of the water coming out.
After all of that, I'll open the gray tank to let the gray water flush and clean out the sewer hose.
I don't think it matters much. These clear sewer hose connectors are useful so you can see how clean the water is coming out.
One last thing I'll do is close the Black Valve, and run the sprayers for a minute or two. I leave the valve closed; I leave that water in the black tank. I prefer to always have some amount of water in my black tank.
