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

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 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.

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

It cleaned my seasonal RV’s black tank and reset the sensor. 2 weeks later, the sensor read 2/3 full again without any use of the toilet. Trying it a second time, hopefully it works for good.

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.

Great product. Cleaned well and the tank odor was completely gone! Will order more as needed!

Works well, easy to use.
