Unique Restore-It RV Black Tank Sensor Cleaner Liquid - Cleans and Restore Misreading Sensor Probes by Removing Stuck-On Waste - 2 Treatments Per Bottle (32 oz)

My black tank sensors were stuck when I bought my RV used in 2023. After trying a few home remedies and 4 months into ownership I ordered this product. My RV tech dismissed it immediately. Said that stuff never works. Well he was wrong. I live in my rig full time and was only able to leave in to soak for 24 hours. Before I dumped I noticed the sensor seemed to be working. I dumped and sure enough it was working. After a fresh water flush and dump and proceeding as normal it's all good. Sensors are working and the tank doesn't smell as bad as it did before the treatment. This product works and I highly recommend it if your black tank sensors have quit working. Only thing it can't do is fix a faulty sensor. Also, I shopped around and Amazon has the lowest price on this item.

I’ve tried many different tricks and many different products that people have recommended at all of the campgrounds I’ve stayed at. I finally found this product online and I said well I’ll give it a try so I ordered it. It came in the mail. Shipping was fine no problems followed the directions on the bottle exactly Emptied the tank filled the tank flushed one more time. My sensors worked perfectly the first time since I owned it and it’s only two years old my camper. This stuff really works. I recommended 100% and you follow the directions 100% on the bottle.

Well I thought this was going to clear up my issue with sensors but it didn’t work for me. Perhaps it was my fault I didn’t get enough water in blank tank Only way to see if it was filled was to look down toilet but couldn’t see so in fairness could have been my fault.Updating waited another day using it regularly to my surprise checked my sensors they are working so let’s rate it 4 stat

Have used more than once to get an empty tank read from RV sensor. Works every time, with no driving around required.

Quick review is that it didn't work for me and I can't recommend it because of that. Long review is that 3 of the 4 sensors on my black tank are always on. So because I knew I would be away from the trailer for awhile visiting family, I followed the instructions and applied a single treatment to the black tank. The label says it will work in 12-72 hours. Well, almost 2 months later upon my return I fully expected all sensors to be cleared. But to my disappointment, after flushing and rinsing my black tank twice. The same 3 sensors were still illuminated. I'll update this review if I find out there is an electronic issue causing the sensor issue and not some stuck on junk.

Great product and works well. Used it twice for best results. Pay attention to tank rinse times!

Worked just as advertised. Worth getting

Didn’t do anything but waste my money and time. Followed directions to a T. Drained an flushed black tank 3 times. Filled black tank full. Poured half bottle In tank through toilet. Left in approximately 80 hours. Drained and filled 3 more times. All sensors still showing full. TT only 3 years old. Always have used unique products. Makes me wonder if the others are any good
