Review on 🚽 Caravan RV Sensor and Tank Cleaner: Enzymatic Formula to Fix Sensor Issues, Clear Clogs, and Ensure Efficient Plumbing in RVs and Marine Vehicles by Gopal Baltimore

Worked great! We bought a used RV and the dealer insisted on draining the tank even though the gauge showed the black water tank was full. He mentioned that the sensors are probably old, but after looking into the issue we realized they just needed cleaning. We bought this after reading the reviews, filling the tank completely with clean water and using twice the amount of cleaner than recommended. They left it for 2 days (didn't work), drained the tank and the sensors show it's empty. This product comes highly recommended
