The Unique RV Digest-It Ultra Liquid is a specialized toilet treatment designed for RV black tanks. It uses a concentrated enzyme formula to break down waste, toilet paper, and other solids, making it a practical choice for full-time RVers and weekend campers alike. This bottle provides 32 treatments, offering a season's worth of coverage for most users.
In real-world use, this liquid treatment stands out for its ability to control odors naturally.

Many users report cleaner tank sensors and fewer clogs after switching to this product.
The design is straightforward: a simple liquid bottle with a cap that allows easy pouring into the toilet. It is safe for all RV plumbing and septic systems, so you can use it with confidence. The concentrated formula means a little goes a long way, and the 32-use count makes it easy to budget for your trips.
One possible drawback is the handling of the liquid itself. Pouring from the bottle requires care to avoid splashes, especially in tight RV bathrooms. Also, some campers may find that they need to use more than the recommended dose in extreme heat or with heavy toilet usage, though this is common among liquid treatments.
Overall, the Unique RV Digest-It Ultra Liquid is a reliable and highly rated tank treatment. It delivers on its promise of breaking down waste, reducing odors, and maintaining a clean black tank. For RV owners looking for an effective enzyme-based solution, this product is a strong contender.
How RV Toilet Treatments Work
Most treatments do two jobs. First, they control odors by masking or neutralizing smells. Second, they break down waste and toilet paper so that the tank empties cleanly. Treatments use different methods to do this:
- Enzyme treatments: enzymes break down waste and paper. Unique RV Digest-It Ultra uses this approach.
- Bacteria treatments: live bacteria digest waste naturally. Septic-safe bacteria packets work this way.
- Chemical deodorizers: strong formulas focus on odor control and fast results.
- Drop-in tablets: pre-measured pods that you drop into the toilet, such as Camco TST MAX Drop-INs.
How to Choose the Best RV Toilet Treatment
The right choice comes down to odor control, waste breakdown, safety, and value.
- Format: Liquid, Tablet, or Packet: Liquids let you adjust the dose for tank size and temperature. Drop-in tablets are the cleanest and easiest option because there is nothing to measure. Camco TST MAX Drop-INs control odors for up to seven days per tablet.
- Odor Control: If odor is your main concern, choose a treatment with a strong deodorizer. Liquified RV Toilet Treatment uses a pleasant orange scent, and Camco offers both scented and orange versions of its tablets.
- Waste Breakdown: Enzyme and bacteria treatments are the best at liquefying solids and toilet paper. This helps prevent the dreaded pyramid plug and keeps tank sensors more accurate. Unique RV Digest-It Ultra is designed for strong waste and paper breakdown.
- Safety: Choose a treatment that is biodegradable and safe for septic systems, especially if you use campground dump stations connected to septic tanks. Liquified products are biodegradable, and the Cabin Obsession packets are septic safe.
- Value: Compare the cost per treatment, not just the bottle price. Unique RV Digest-It Ultra offers 32 uses per bottle, and the Cabin Obsession pack provides a full year of monthly treatments.
How to Use RV Toilet Treatment
- Empty and rinse the black tank completely.
- Add enough water to cover the bottom of the tank, usually two to five gallons.
- Add the recommended dose of treatment through the toilet.
- Use plenty of water with every flush to keep waste moving.
- Dump the tank when it is about two-thirds full for the best flow.
Clean the bowl as well as the tank. A gentle, septic-safe cleaner such as the Liquified RV Toilet Bowl Cleaner removes stains without harming seals. If you need a toilet for your RV, read our guide to the best RV toilet.
