In this article, we will dive into each of these five reasons in more detail to further explain why RV Digest-It is the best RV holding tank treatment available!


As many RVers know, properly maintaining your wastewater systems is a crucial part of keeping your RV experience fun and enjoyable. Ensuring your RV remains clog-and-odor free requires two things:

  1. The Unique Method
  2. Using the right holding tank treatment

No matter how great it is, no product is a magic bullet, so even if you’ve selected the perfect treatment for your camping style, without a good understanding of proper wastewater care, you're not going to have an optimal experience.

Once you understand how to properly care for your RV’s wastewater systems, it's important that you select the highest quality treatment. By all measures, RV Digest-It meets and beats the highest expectations for a top-tier holding tank treatment.


The ingredients we use in RV Digest-It are hand selected for their safety and efficiency. These ingredients are designed to maximize your wastewater system’s performance.

Waste Digestion and Odor Control

RV Digest-It is hands down the best performing treatment for solid waste break-down and odor control.


At Unique Camping + Marine, we specialize in wastewater products. We make our products the right way, and we’re constantly improving. By keeping our ears close to the ground and listening to what the RV community is telling us, we can provide superior products that customers are actually asking for!

We test our products relentlessly, making sure at every turn that they stand up to our promise of quality. We sometimes tweak our formulation or refine our ingredients so we are constantly improving our products wherever and however we can.

Frequent iterations of RV Digest-It allow Unique Camping + Marine to provide the best holding tank treatments available, outshining every other traditional RV toilet chemical.

By making a probiotic holding tank treatment that lubricates valves and seals, cleans sensor probes and level gauges, and prevents clogs and odors, RV Digest-It has become a powerhouse that helps you enjoy your RV without worry.

The cherry on top? We stand behind RV Digest-It (and every other product we make) with a 100% satisfaction guarantee. So if you don't like how it works, it’s on us.

Formulated with Trust

Part of our commitment to making RV Digest-It the best holding tank treatment available is selecting ingredients that pose as few risks as possible to humans and the environment. RV Digest-It is formulated with trust, meaning we are not bashful about telling you exactly which ingredients we use so that you have the ability to look up those ingredients and see for yourself if our product meets your personal safety standards.

Carefully selected ingredients combined with highly effective formulas ensure that RV Digest-It is the best alternative to corrosive ineffective RV toilet chemicals that can even damage components of your RV wastewater system. Our probiotic blends use naturally-occurring bacteria that are the most effective tool for completely breaking down solid waste (including all brands of toilet paper) and removing odors.

Fragrances are used sparingly in RV Digest-It (because we aren't masking smells!) and are hypoallergenic and naturally derived. Because RV Digest-It eliminates odors at their source, heavy, masking fragrances simply aren't necessary.

Customer Support

At Unique Camping + Marine, we’ve dedicated a huge amount of time to building resources and guides that help the RV community. All of our guides are written with you, the RVer, in mind. Ultimately, we want to make the joys of RVing more easily accessible, and a big part of that is making sure you get the help you need when you need it.

Our support team is made up of people who care about your RV experience, so whether you’re an RV renter, new owner, full timer, or just weekend warrior, we’re here to assist you

If you need a little more convincing from someone else, simply read some of our reviews to get a better impression of what people are saying about us! Here is just a sample:
