I do the same except I have two tornado rinser's in my black tank and I usually clean it twice (I am a bit OCD about my black tank).

Nope.......
I dump, then flush/rinse using OEm flush system with drain open then I close the drain valve and let the flush system flow. After about 5 mins I open drain valve and let the higher volume/level go whoosh. Then close the valve wait 30 seconds or so and shut down flush system (puts a few gallons or so of water back in tank for next time)
Then I dump grey tanks and pack up.......done
I'm not real OCD about waste tanks.......dump when full, rinse, add few gallons & call it good. They are going to get dirty again real soon.
