The Problem

During normal use of your RV, your black water holding tank will get filled with solid waste and buildup. We may rinse our tanks before storing our RV’s, thinking we’ve taken care of cleaning our holding tanks, but solid waste (feces, toilet paper, etc.) and other buildups don’t always get fully rinsed out of the tank. This left over waste can go unnoticed, so the next time we go to take an RV adventure, we’re instantly plagued by odors, backups, and misreading sensors.

The Solution

Unique’s Biannual Tank Maintenance Pack is a specially designed pack to be used at the beginning and end of the RV season to obliterate even the most stubborn tank buildup, leaving you with sparkling clean, flowing, and odor-free holding tanks, so you can hit the road without worry. The powerful products in the Biannual Tank Maintenance Pack are specifically chosen for their ability to cut through solid waste and toilet paper using only the highest-quality blend of bacteria and enzymes.

What's Included:

Tank Cleaner

Waste sitting inside the black water holding tank for long periods can tend to build up and cause odors. Unique’s powerful blend of bacteria and enzymes get down into every nook and cranny in your holding tank and begin to break down the waste. As the enzymes break down the waste, the probiotic bacteria kick in and begin to eat the waste, leaving nothing behind but clean-running tanks.
