Moral of the story! After every dump, before hitting the road, add some water again and add the Dawn so it can pulverize the inside of the tank and wash out all the "nasties
Never had the need to add anything to the black tank other than water. We camp seasonally and dump the black tank once a week. Every time I dump the tank, I refill with water, then dump again. Then I let the in tank rinser run for a few minutes until the water is clear.
The only time we get odors from the tank is if it gets too full and the vent is blocked.
