I never use any of this stuff, or any kind of chemical either.
No way that during a 3-4 period these "magic products" can dissolve anything !
Just plain old water...plenty of it when we camp, back flush when we dump, and 4-5 gallons of water in the tank after back flush is done and hit the road and let it slosh around.
When I get home, empty the tank again in a bucket and dump in toilet.
Never had an issue and the sensors always read good.
