Powered By The Most Advanced Bacteria & Enzyme Formula Available

Hands down, RV Digest-It is the most effective waste digester and odor eliminator available.

We get it, you want both: odor elimination and waste removal - so why settle for only one or the other? Savvy RVers know that keeping your holding tanks clean is extremely critical to enjoying your RV. Nothing ruins an RV adventure like toilet troubles!

RV Digest-It’s probiotic and enzyme formula is the most advanced formula available today and contains the highest quality, hand-selected ingredients. It is made in Colorado using ingredients and materials sourced in the USA, and there is no other product available that can match its ability to prevent clogs and odors in black and gray holding tanks.

Thousands of RVers trust RV Digest-It Holding Tank Treatment everyday as their go-to solution to properly maintain their holding tanks.

RV Digest-It uses the most powerful blend of bacteria and enzyme cleaners available to keep your RV clog and odor free. RV Digest-It is the most affordable and effective way for RVers to treat both their gray and black tanks; prices start at only $.63 per treatment!

RV Digest-It is also completely safe, meaning it's the perfect non-hazardous and eco-friendly solution for you and your family! The best part is, your satisfaction is 100% guaranteed, so there really is no risk! 

Many other treatments do a good job of eliminating odors but do nothing for solid-waste digestion. In fact, many odor eliminators will actually damage your RV by coating your lines with mineral deposits that damage your toilet bowl, your seals, and cause your level sensors to constantly read full.

Now you can get both with RV Digest-It: Unbeatable odor control and best-in-class waste digestion. And you can get it all for under $1 per treatment!

The RV Digest-It Difference. Other treatments leave behind damaging residue that coat your RV’s plumbing with mineral deposits, resulting in clogged toilet bowls, compromised seals, and level sensors that constantly read full.

RV Digest-It’s eco-friendly formula goes to work on your camper's toilet by injecting billions of healthy bacteria into the holding tank that break down and biodegrade all of the contents that cause odors and backups.

Expensive RV toilet paper is unnecessary if you are maintaining your RV wastewater systems with Unique RV Digest-It. We guarantee that all of your black and gray tanks will be flowing smoothly, including those using household toilet paper.

Our Guarantee. We know you’ll love RV Digest-It! Because everything is turned into liquid, dumping is always a breeze! Its non-toxic formula means it’s safe for people, pets, and the environment, and it comes with unparalleled support from the tank experts at Unique Camping + Marine. But if for some reason you don’t love it, we’ll refund your money without hassle!

Wonderful customer service

They stepped up and corrected a problem with shipping . They reshipped the product immediately at their own expense when Fedex ******* up and didn’t deliver the product to me. Will do business with them again.
