Review on Happy Campers - Extreme Tank & Sensor Cleaner: Top RV & Marine Cleaning Solution for Unmatched Cleanliness by Michael Vargas

Everyone likes this product, so I gave it a try. My black tank sensor was working fine until I tried it and now even though the black tank is completely empty the sensor says it is 45% full. My biggest issue with the product is that nowhere on the label or on their website does it say what the ingredients are. I contacted the manufacturer and asked about the ingredients (no answer). I read their MSD sheet (ingredients not listed). I asked the campers on You Tube who use and love it but none of them could tell me what it really is. I think it's overpriced TSP (Trisodium Phosphate) that I can get at Walmart for way, way less than the expensive mystery product that ruined my sensors.
