Did My Research After Trying Many Others – This Is the One! After trying several RV toilet treatments over the years with mixed results, I finally did some serious research before my next purchase—and Unique RV Digest-It+ is the one I landed on, and so far I'm convinced it's the best I've used. The extra-strength formula does an impressive job of liquifying waste and breaking down all brands of toilet paper without leaving anything behind in the tank, which is exactly what you need for a clean, problem-free black tank. The odor elimination is noticeably effective—no chemical smell, no unpleasant odors coming back up through the toilet, just genuinely fresh results. For RV use where black tank maintenance is a critical part of every trip, having a treatment you can actually trust makes a real difference in the overall experience. It's also reassuring that it's safe for all RV and marine holding tanks and septic systems, so there's no concern about damaging seals or sensors. After testing many products, this one stands out for its effectiveness, reliability, and clean results. If you've been bouncing between RV toilet treatments looking for the right one, do yourself a favor and make this your last stop.

This product worked very well using the instructed amount. It appeared to break down the waste well and eliminated the toilet odor

This stuff is amazing. I’ve been using it for about a year now, and it truly breaks down all the solids in the holding tank into a liquid or sludge, which makes dumping so much easier. It does exactly what you want a tank treatment to do — everything dissolves properly, and there’s no buildup left behind. One of the biggest benefits I’ve noticed is that my tank sensors have become much more accurate since using it. Anyone who owns an RV knows how frustrating those sensors can be, so that improvement alone makes this product worth it. Overall, it’s effective, reliable, and makes tank maintenance far less of a headache. Highly recommended for any RV owner.

this helps with the odor. The scent is not too strong it doesn’t really digest it so to speak, (are there any that really do?) but it does the job of helping keep the odor away in your black tank. I love how you can squeeze it and it measures it by itself or in the little thing and then you just pour it over and you’re not pouring too much. I’d love that part I would buy this again and again seems super safe and easy to pour.

Revised: Works great now. The awful outhouse odor that we’d been experiencing is no more. I re-read the instructions that clearly said to shake contents vigorously before filling 1oz tube. Once I did that, no odor!

This is the GREATEST RV tank additive I have ever used in 50 years of owning RV’s!!! I have full timed in my Pace Arrow since it was new in 2004. Your product has cleaned the black and gray tank like nothing else I’ve ever used! And there is NO ODOR AT ALL!!!! I am a customer for the rest of my life. BUT! Today my two bottles came and one had opened during shipping! Only a quarter of the bottle was left. The box was soaked and falling apart. I’m trying to get it replaced now.

I like it I would buy it again. I do say it was the best toilet treatment that I ever used for my RVs. I did have a pyramid plug, but I did have to use the whole bottle. It worked with breaking up tissue and breaking up the pyramid Plug, but I still had some lingering smells. I’m going to at least keep it in my toilet for 3+ weeks because my septic system is not full yet and I only get it dumped out about twice a year because I have a large septic system so it will have a lot of time in my system to work but at the same time it took the whole bottle to be able to get rid of the smell and actually work I know it stated that it was 32 treatments. It was a little less than $30 and it was only one treatment for me. I did use about 20 gallons of water after just to push everything through the system. I live off grid where I don’t have a lot of water to spare when flushing I do the best I can so I probably wouldn’t have this problem if I had endless water to where I can use as much as I needed it to flush and also keep some water in my toilet bowl afterwards, but it did help me with my problem, but I did have to use the whole bottle so it was worth the $30 to help me with my problem, but most definitelyexpect to use the whole bottle at least half of the bottle when purchasing
