Was wondering if any body just dumps and calls it a day? Do you add any water?
The best cleaning action I've found for black tanks is driving down the road for an hour or more with 2-3 gallons of water in the tank and whichever chemicals you use.
As full-timers and NPS/COE/BLM/FWS/USFS volunteers, we sometimes stay put in one location for one to four months. Then I flush the black tank about once a month.
We've used an enzyme product and been very happy with it for a couple years. Never had smells.
