Unique Clean-It RV Black Tank Cleaner Liquid - Effectively Resets Dirty RV Black Tanks - Eliminates Odors and Waste (32 oz) Amazon Exclusive Packaging

We recently used this on our 5th Wheel black tank and cannot say enough good stuff about it!! Our tank sensors began reading FULL after our second or third trip, even with excessive rinsing and cleaning after each trip. We are in our second year of our ownership and travel just accepted the fact that our sensors (as most complain about) would never work again. So we followed the directions on the bottle. Filled our black tank (49 gallon tank) added the bottle of cleaner to the tank and parked it for about 2 weeks (in between trips). We dumped our tanks when we arrived at our next campground, dumped our tank and rinsed well. No odor, no issues and best thing yet? Our sensors once again read accurately!!! It's a little thing, but it's a great feeling! We use a few of the Unique brand cleaners and treatments and have been thrilled with the ease of use, quality and performance of them. Good size bottles and I feel the price is well worth the results you receive. Nice to have products that are seal and tank friendly and safe to let sit in the tank for extended period if needed. Highly recommend this deep cleaner and all of the Unique products for care and maintenance of our rig!

I've used several other products to try and clear out my black tank which had built up sludge from the previous owner. Nothing worked until I tried this stuff. I followed the directions for full time RV'ers and holy cow did it work! It got everything in there out and even cleaned off the sensors to show the true level. I cannot praise this product enough and I will use it on my mother's camper and will suggest it to everyone I know. You cannot go wrong with this stuff. I just hope the formula never changes and I can keep buying it.

I do love Unique products and all they stand for. This one is no different. I purchased this Unique Clean-It RV Black Tank Deep Cleaner Liquid after purchasing a used 5th wheel that someone didn't fully clean out after a toilet pyramid took place. I figured I would give it a shot. I will say after pouring in the bottle and then regular daily use, it is better. There is still some more cleaning to do, but the smell is much better. These Unique products clean, are easy to use, they are safe, and also safe to use on a septic. I highly recommend Unique over the smelling products out there. I'm not looking for a scent, I'm looking to clean.

Easy to use and effective

Worked the best out of all I’ve tried so far

Followed instructions and work wonders.

Just bought a used 2021 Rockwood MiniLite 2507S, found out it came with a full black tank. When I went to dump it the flow was extremely slow, figured something was clogged. So I bought this cleaner and added it a few days before we planned to take it on a long trip. The day before we were leaving I stopped down to my local Camping World dump station. I hooked up the sprayer on the back and turned it on to get tank as full as possible, and went inside to watch level from the toilet. Once it looked full I went out and opened the dump valve and whoosh!!! It did a great job breaking up whatever restrictions there were and tank ran super clear at the end. Great product.

I've used this product a lot and for some reason, I just am not getting the results I expect. Last time I used, I let it sit a whole week in our tank after doing a complete flush. I will say the #2 sensor showed clear a lot quicker than normal, but my elusive #1 bottom of tank sensor just will not come clean. Tank flushes clean after use, but that one sensor is not getting the stuff off of it. I am otherwise a continued user of these products as so far they are the best out there I've found to date. Oh and I do follow their directions to the "t"
