Impressive!

I reside full time in a small RV; step on toilet flush peddle — water runs and opens toilet hole flushing to black tank, drop one pod in toilet hole followed by hot water (I boil water in tea kettle), I “clean” monthly, instructions says less often. let pod work its magic for several hours or overnight to break up solids. Then, do black tank drain to sewer/septic… Tada!

Commando never disappoints!

The worst part about camping are the holding tanks! Commando is the best tank additive! We use it regularly. It makes camping smell so much better.

Our trailer sensors in the black tank have not been accurate. Followed directions and Bingo. We got a reading of 0 when the tank was empty!
