Review: Happy camper - Our camper sensor read 3/4 on the black tank since we bought it used. Used this and let it sit for the 24 hours and now reads empty and the smell is gone!
Review: Works very well! - My Black Water tank sensor was not reading. I put this product in the empty tank, and filled 3/4 full with water. Within two hours, sensor started reading, looks to be accurate. Going to drive and let the cleaner slosh around anyway, but seems to do what it says--clean the sensors!
