    Traveling in an RV provides a feeling of freedom that nothing else can. But sometimes issues like a clogged holding tank can ruin that free-wheeling feeling. You need something that is going to unclog your tank quickly, and safely. Unique Tank Cleaner is hands down the strongest, most effective way to break through waste that is clogging your RV toilet or holding tank - guaranteed!

    Unique Tank Cleaner goes to work quickly (overnight in most cases) to break down and liquefy the solid waste that is clogging in your black water tank. Many other products claim to clean and unclog holding tanks, but our research and consumer feedback have shown that these other treatments are ineffective in unclogging tanks and many of them actually end up doing more damage by adding scale and mineral deposits to the tank that can cause sensor probe malfunctions.

    Unique Tank Cleaner is by far the most effective tank cleaner on the market today and is trusted by RV service departments from coast to coast as their go-to solution for unclogging customer’s holding tanks when they bring them in for service on a pyramid plug or plugged toilet.

    Unique Tank Cleaner is fragrance free, formaldehyde free, non-toxic, and proudly made here in the USA. Best of all, Unique RV Holding Tank Cleaner is backed by a 100% money-back guarantee.

Didn't Notice Much Change - Still Plugged

My blank tank is clogged solid. I tried back flushing it (hose up the the outlet), I tried a cleaning wand, and I even tried a plumbing snake. Nothing worked. Just had a huge and nasty mess to deal with. I added one bottle of the Black Tank Cleaner and as much water as I could and let it sit overnight. In the morning I was able to add a bit more water but the tank was still plugged. I added a second bottle of the cleaner and let it sit for a couple of days, adding (hot) water from time to time as it drained down. Still plugged. From the marketing (and the price), I was expecting a miracle. Very disappointed that the product doesn't live up to its hype. I mean it worked a little in that I was able to add water and have it drain down over a period of time, but I was really expecting better results. I'm so desperate to solve this issue that I'm tempted to buy more, but just can't bring myself to do it given the price.

I did two treatments to my RV black tank using this product. I followed directions written on the bottle. I did not notice any difference in cleaning the black tank using this product than using other products.

Tank cleaner

It did not work at all. The pyramid plug didn’t move one bit. It has now been in the tank for three days. Added as much water as possible. Still nothing.

Great product!!

I got this because I bought a used (very used!) RV where the previous owners had totally neglected the tank. I used the product and flushed my tank. At first it seemed like only small bits were coming out, which made me nervous. After running my tank flush for a few minutes though a huge amount of waste came out! I couldn't be happier. Great product!!

Unique Camping + Marine

Thanks for the shining review, Eric! So glad we were able to help you out!
