Effectively Cleaned RV Black Tank Sensors
Despite using tank cleaning drop-ins regularly and using the tank flush, we would consistently a 1/3 full reading immediately after emptying. We dropped one of these into the tank, filled per instructions and let the solution sit for approximately 12 hours. Emptied and tank flushed again and after a moment or two, the tank indicated as empty so it worked perfectly! The only think I wish is that these RV necessities would be less costly - on a cost per use basis, we are paying just over $4 per drop-in (after tax). True, you shouldn't need to use them very often but that's still a lot. They do work though, so I guess my mindset should be that you get what you pay for.

Worked great on black water tank
Used this product in 3 separate holding tanks in my RV. Cleaned two of them right out with both of those tanks sensors now registering completely empty once drained. The tank for the kitchen didn’t clean up as well, but after a little more research it looks like this product isn’t made for that type of tank and that the same company makes a different product that can handle the grease and such that a kitchen sink gets. Based on my success with this product in the 2 other tanks I’m going to order and try their kitchen sink fix as well. Will recommend and use this product again.
