I have a flushing system but clean out best when I can dump and refill with one-third tank "fresh" water and a healthy squirt of dishwashing soap. Then I take it down the road to the next destination and dump when I can. Amazing results!
Exactly what I do except I use a laundry detergent (Oxy Clean). Dump before leaving, add several gallons of fresh water and soap and drive. Sometimes, I'll even add a cup of Calgon water softener to coat the inside of the tank to make it slippery.

RV'n over 40 years, never had a flush or a wand !
Just a little blue stuff, and my tanks are spotless.
Try it without the blue stuff...total waste of $$. Water will do just fine.
