RV Digest-It RV Toilet Treatment - Eliminates Odors at the Source and Liquifies Waste - 16 Uses Per Bottle (32 oz) Amazon Exclusive Packaging

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.

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!

Game changer and so easy to use. Love the bottle so you can dispense exactly the right amount!!!✅. No mess!!! Have noticed a difference in the clean outs… just liquid.

If you’re looking for a chemical that does a really good job then look no further than. I noticed since I started using this companies chemical my black tank No Longer smells! It really does a good job on getting my Black tank cleaner. Instead of cleaning my black tank 3 to 4 times…. I’m now doing it just Twice. Thumbs up for this product!

Keeps odors from tank to a minimum and cleans sensors everytime.

Have owned campers/RV for decades. I have used many different black tank chemicals. Some worked a little, some didn't work at all, this is the best treatment that I have ever used. I am done trying other products, this is the only one that I will be using. One oz per 40 gallons and when I dump black tank I have Never seen any solids or toilet paper going out. I have a clear straight pipe and a clear elbow to monitor the discharge. I back flush using tank clean out every time and still nothing but water leaving. Every so often I will use a flash light and look down into the toilet with the water turned off so I get a good view. Have seen Nothing but the clean tank bottom. Works Great.

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

Being new the RV life we wanted to find a black tank product that was easy, powerful and practical. We are very happy with this product as it checks all the boxes! No more pyramids, no more toxic smells, and easy tank drainage! This will be our only black tank product going forward!

When the black tank is drained, waste flows easily because it is broken down ... no more clogs and no more stinkies.

Breaks down waste nicely. Although costly product.

Works great and was the best from the research I did, but ended up finding something different that worked better. But this is still a great product I recommend it

Rv black tank treatment works great and smells amazing.
