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!!

Not impressed

Left it in 5 days. Not much came out. And it took awhile to get here.

Hi Rachel, Thank you for taking a moment to review Tank Cleaner! I'm sorry that you didn't get the results you were hoping for! Were you using it because your tank is totally clogged or were you just trying to clean it up a little? If your tank is still clogged I'm confident we can help you solve that! If you're just trying to clean up a little we can also help there! Either way, we'd really love to help you. Just shoot us a quick email at and we'll get started on it right away. Again, thank you for sharing your experience! We hope to hear from you! Ricky Unique Camping + Marine
