    This worked great. We had a blockage and there was nothing coming out of our black tank. Put this in, filled with water and a few days later there was no more blockage and it emptied easily.

    Worked like a charm. Our trailer sits all year round as we don't travel with it. We had a pyramid plug. We let it sit for 5 days and the clog is gone. Will probably do this again at the end of the season.

    4.0 out of 5 stars It cleaned the sensors in the black water tank
    Reviewed in Canada on July 5, 2025
    Verified Purchase
    It seems to have helped cleaning the sensors in the black water tank of our camping trailer. Previously, sensors were always indicating 3/4 full even if the tank was empty. I kept Clear-it in the tank with water for 4 full days. One day after I emptied the tank, sensors were back to one light only.

    Le produit est dispendieux et s’il y a des cheveux qui bloquent l’écoulement de votre réservoir, ça ne fonctionne juste pas.

    5.0 out of 5 stars The product works great.
    Reviewed in the United States on July 3, 2025
    Verified Purchase
    I recently purchased a used Mercedes-Benz Sprinter van from an older couple. It was well-maintained, except for a bad smell in the restroom. I tried to flush and refill the black tank several times, but the smell remained. I saw a short video clip on Facebook about "Unique Clear-It RV Black Tank Unclogger" and ordered a bottle. I poured it in and then filled the tank up. I let it sit for three days and then drove it to the dump station and flushed and refilled the tank twice. The issue was resolved. Now I'm a happy camper.

    Reviewed in the United States on July 22, 2025

    I live full time stationary in a fifth wheel. For the last four years this has been my go to anytime I have a clog or build up in the black tank. This time I'm pretty sure it was caused by my potty training granddaughter deciding to hide an "accident" by flushing her pull up and the enormous amount of toilet paper she used trying to clean herself up. It was horrible. But I ordered a bottle of this and it took the entire bottle and about three days but it dissolved it and allowed the tank to start draining again. Only thing I ever use when there's a problem.

    4.0 out of 5 stars Might not work alone with the hard clogs
    Reviewed in the United States on May 11, 2025
    Verified Purchase
    My clog was bad and in the pipe due to a valve not closing all the way and I didn’t know. So the clog got really hard in the pipe. I had to drill a little tiny hole in the pipe and take my little wire in the pipe to break some of the clog away so I could get it to drain. I thank fixed the hole with PVC cement. It did drain and I replaced the valve. Than I put this in for 4 days. A combination with the cleaner and the flush king did the job

    1.0 out of 5 stars DOES NOT WORK FOR CLOGS
    Reviewed in the United States on May 11, 2025
    Verified Purchase
    While I believe this product would work well for pyramid poo it’s not strong enough to break through a clog or blockage. Instead, it simply added volume to the sitting water in my toilet. I let it sit for 4 days with absolutely zero change. Bought a toilet auger and that fixed my issue immediately. Going to reach out to the company and see if they stand by their product or not, I can’t return an empty bottle.

    Didnt seem to work for me, had a clogged black water tank that just refused to drain, poured it in along with the reccomended amount of water but had little to no effect even after waiting a week. Eventually had to have the tank pumped by a service company.
