Unclog Your RV Holding Tank Hassle Free

Many RVers are surprised at how common RV holding tank clogs are. Even more common than a clogged holding tank is build-up and poo-residue throughout the season. The go-to solution is often to just wand your tank and to get your hands dirty, or by using a service technician to do it for you; charging you hundreds of dollars. The results can be inconsistent and expensive.

With Unique Holding Tank Cleaner you can restore your tanks without expense or wanding.

Throw out your wand and see why RVers nationwide have switched to Unique Holding Tank Cleaner to deep clean their RV black tanks. Unique Holding Tank Cleaner uses the strongest bacterial cleaners available to break down clogs and solid waste build-up in your RV black tank. Simply put, Unique Holding Tank Cleaner is stronger, more effective and higher quality than ALL of our competitors. We want to get you back on the road as fast as possible doing the things you love. The best part is that it often works overnight! Why spend more time on your holding tanks than you need to?

Don't waste time, effort and money when we can do your dirty work!

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!!
