Unique Restore-It RV Tank Sensor Cleaner Liquid, Restore and Clean RV Black Tank Sensors (32 oz)

I have tried many rv tank cleaners and this is the only one that works. You follow the simple directions and leave it in the tank as long as possible. Your tank sensors will be clean. I use all the Unique product line

Filled the empty black tank as directed. Poured in the solution into the toilet into the black tank. Waited 2 weeks, emptied the tank. Before the cleaning process, all 4 level lights were on even when the tank was empty. After cleaning, only the empty tank was on. Great!

I had sensors that were always on and I put water in the tank and let it soak for a few days. after draining the tank the sensors work properly

I like the price, the experience of delivery and easness of orsering

Fixed long-standing black water tank sensor problem in our RV Camper.

used this for years, it works. Twice a year.

I didn't think it would work but it did n I will be using this product from now on.

Just another concoction that doesn't seem to make any more impact than Dawn dishwashing liquid and Calgon water softener combination. Since Dawn %26 Calgon costs a whole lot less, it doesn't make sense to overspend and receive little to no different results.

The description sounds like this is the answer to fouled gauges...I have used this a couple of times with moderately poor results. Thought I would try it one more time with a triple dose. Once while the RV sits for about 80 hours and a completely full tank. Then a good rinse and a double dose with about 2/3 tank and an 800 mile trip of it sloshing around. If I still don't see favorable results I will just live without a gauge reading, or put new ones in.

Used it per instructions and had no effect on sensors.
