  • Got the stink out
Style: Orange Size: 32 Fl Oz (Pack of 1)
We’ve used our 2024 RV about 10 times this year for trips that vary from weekend state park escapes to 2-week ski trips. We’ve used the other top-rated products, but for some reason we’ve really fought with black tank smell in this trailer more than our previous rig. I finally chose to try Matt’s Liquified, which I had resisted, thinking that it was just a name-centered brand (Matt is a popular YouTube content producer). Two things I love about this product: the bottle design makes dosing easy and prevents messes - which means you’ll only use what you need for each treatment and you won’t waste any through spillage or over-dosing. 2. It works. We’re not fighting bad black tank odor anymore, and we don’t have to dread heading to the bathroom. (lol - IYKYK). It’s hard to think of anything I don’t like about Liquified. It’s a great product at a reasonable price. ... show more

  • A Must-Have for Any RVer
Style: Orange Size: 32 Fl Oz (Pack of 1)
Having used various RV toilet treatments over the years, I felt compelled to share my experience with the Liquified RV Toilet Treatment, which has been a game-changer for our family's RV trips. From the first use, I was impressed by its effectiveness and ease of use, and I'm confident that other RV owners will find it just as indispensable as I have. First off, the product's features are top-notch. The liquid formula is super concentrated, making it incredibly efficient—you only need a small amount to achieve results, which means a single bottle lasts a long time. It's also biodegradable, which is important to us as we try to be as eco-friendly as possible in our travels. The fact that it's safe for all septic tanks was a major selling point for us, too. Performance-wise, the Liquified RV Toilet Treatment exceeds expectations. It effectively breaks down waste and toilet paper, preventing any clogs and unpleasant smells. We've used it in a variety of climates and conditions, from high heat to cooler temperatures, and it's performed flawlessly. The pleasant scent it leaves behind is not overpowering, just fresh and clean. It's a relief not to worry about odors, especially when we're parked for several days in one spot. Regarding value for money, I believe this product is worth every penny. Given its efficiency and the small amount needed for each treatment, it offers great longevity. We've saved money in the long run because we're not constantly buying refills or dealing with maintenance issues related to tank clogs. Additionally, the peace of mind knowing we're using an eco-friendly product that won't harm the environment or our RV's plumbing system is invaluable. In summary, the Liquified RV Toilet Treatment has been a fantastic addition to our RV supplies. It's easy to use, effective, eco-friendly, and economically efficient. I highly recommend it to any RV owner looking for a reliable toilet treatment solution. Say goodbye to the hassle of dealing with tank issues and hello to more enjoyable, worry-free travels! ... show more

  • This stuff works great!
Style: Lavender Size: 16 Fl Oz (Pack of 1)
This is the first time I've bought in the lavender scent but I've used the original and I works like a charm. Just got done with a week long trip and never had any smell in the RV. We've tried probably 6 other types of black tank treatments and none of them ever digested or kept the smell away. Usually by day three, we had to dump because of odor when flushing. Since switching to Liquified, when we dump, everything comes out without issue and was obviously digested extremely well. Highly recommend! ... show more

  • Great stuff
Style: Orange Size: 16 Fl Oz (Pack of 1)
It has a pleasant orange smell and pretty easy to measure out and pour.

  • Works pretty good, but...
Style: Orange Size: 32 Fl Oz (Pack of 1)
From what I can see, (yes, I have a clear sewer hose extension), this stuff breaks down the solids pretty good, but not the toilet paper. The TP still comes out in big clumps. It also does not keep the sensors clean. The only way I can get the sensors to read empty is by sticking a wand down the toilet. I use my on-board black tank flush to almost fill the tank again with water after dumping, but not much more soluds/TP comes out. No black tank odors and the citrus fragrance isn't overpowering like other black tank chemicals we have used. ... show more

  • The BEST RV black tank treatment/cleaner!
Style: Orange Size: 16 Fl Oz (Pack of 1)
I recently started using Liquified RV Toilet Treatment, and I have to say, I'm thoroughly impressed with the results. This product has completely transformed my RV's black tank maintenance routine. One of the most notable benefits of this treatment is its ability to break down buildup inside the black tank effectively. By using the correct amount for my tank size, I've noticed a significant reduction in clogs and blockages. It's amazing how effortlessly it tackles even the toughest waste, keeping my black tank clean and functioning smoothly. Another standout feature is the refreshing citrus scent. Not only does it mask any unpleasant odors, but it also leaves behind a pleasant fragrance that makes my RV feel more inviting and comfortable. Say goodbye to those lingering smells that can often plague RV bathrooms! One of the most surprising benefits I've noticed is how much less flushing it takes to clean out my black tank when it's time to move and pack up the RV. This not only saves me time but also conserves water, which is crucial when you're on the road and relying on limited resources. It's a win-win situation all around. Overall, I couldn't be happier with Liquified RV Toilet Treatment. It's made maintaining my RV's black tank a breeze, thanks to its powerful cleaning action, pleasant scent, and water-saving properties. If you're looking for an effective and convenient solution for black tank maintenance, look no further than this product. ... show more
