Fresh Camper, Zero Odor: A Game-Changer for RV Life
Reviewed in the United States on April 28, 2026Camco TST MAX RV Toilet Treatment cubes have been a total game changer for our camper. From the first use, they made a noticeable difference in controlling odors, keeping the entire space fresh and comfortable. The cubes are incredibly easy to use—just drop one in and you’re set, no mess or measuring required. Even during hot weather and extended trips, they consistently break down waste and prevent that dreaded tank smell from creeping in. I also appreciate how compact and convenient they are to store. If you’re looking for a reliable, hassle-free solution to keep your RV smelling clean, these cubes are absolutely worth it.

A Must-Have for RV Life – Works Well and Smells Great!
Reviewed in the United States on March 6, 2026We have been using these Camco TST MAX drop-ins for our RV trips for years, and they are a permanent part of our setup.
Options & Scent: I love that they come in different scents, though we usually stick with the orange. It’s a very pleasant, fresh smell that isn't overwhelming but definitely gets the job done.
Bottle Size & Value: We typically get the 30-count bottle, which is a great size for several trips. The container is sturdy and keeps the pods dry and fresh until we need them.
Performance, Softness & Leak Prevention: These pods are great because the outer "skin" is soft and dissolves very quickly once it hits the water. My husband handles the tank maintenance, and he's impressed with how effectively they break down waste and tissue. Most importantly, we've had no issues with leakage or clogs, which gives us total peace of mind while on the road.
Safety: One of the biggest selling points for us is that they are formaldehyde-free. They are safe for all septic systems and RV dump stations, so we have total peace of mind regardless of where we are camping.
Verdict: Reliable, easy to use, and effective. We wouldn't go on a trip without them!

No smells!
Reviewed in the United States on May 31, 2026These work really well for us in our camper. Our tank holds around 40 gallons. After dumping the tank I drop one in the toilet and flush for about a minute to add water to the tank. Then. Everytime we use our camper in the summer (2 or 3 times a month) I drop in another tablet in the toilet and do the same thing. This has worked great and we never have had a problem with smell! The box usually lasts me a couple of years. Definitely recommend.

Product great. Delivery not so much.
Reviewed in the United States on June 8, 2026Product works fine. But having it delivered by Amazon in just a brown bag caused the plastic container that holds the product all in the bag. This really need to be shipped in a box. Aleast I can use the product and will have to store it in a Rubber made container.

Our go-to for RV tank maintenance – reliable
Reviewed in the United States on May 1, 2026This has become our go-to brand for maintaining the tanks in our 5th wheel camper. We’ve used several products over time, but we keep coming back to this one because it’s dependable and does exactly what it’s supposed to do.
The drop-ins are super easy to use—just toss one in and you’re set. We’ve had no issues with unpleasant odors while using these, even during longer trips, which makes a big difference when you’re living in close quarters.
We trust this brand and their products, and it’s one of those items we make sure to always have stocked before heading out.

Not the best of scents for an RV Toilet Tank
Reviewed in the United States on February 2, 2026I don't know why I thought the scent of lavender would be great for my black water holding tank, but it's not. I'm sorry to say that I will have to return it. There's 30 Camco toilet 🚽 treatment packets in this container. All you have to do is just drop one of these packets into the toilet and flush it down into the holding tank. I am not saying that this product is not good; I'm saying that I will have to exchange it for a different scent. I won't know until I try a different scent, because I might be allergic to Camco's RV Toilet Treatment Drop-ins. The lavender scent put out such a bad smell, I couldn't breathe all night last night. I had to keep filling up my tank, waiting for awhile, and then dumping it all out. I had to keep doing that till the bad smell went away. So I'm gonna give Camco another chance, and try a different scent, and just go from there. I should have known better than to use a toilet treatment that had a perfume scent. I'm allergic to fragrant's, I have to use fragrance free laundry soap.

Richlife_bigheart5 out of 5 starsRv tabs!
Reviewed in Canada on July 23, 2024Let me tell you about a game-changing marvel in the world of RV living: the RV toilet sewer treatment tab. If you're a seasoned traveler or a newbie to the RV lifestyle, you know that managing the black tank can be one of the less glamorous parts of the journey. Enter these little miracle workers!
First off, the convenience is unparalleled. Just drop a tab into the toilet, and voilà, it goes to work immediately. No measuring, no mess, just a simple, effective solution to a problem every RVer faces. The tabs dissolve quickly and start breaking down waste and paper right away, which means fewer clogs and smoother tank emptying.
What really sets these tabs apart, though, is their powerful odor control. Say goodbye to unpleasant smells wafting through your home on wheels. These tabs neutralize odors effectively, leaving your RV smelling fresh and clean. It’s like having a tiny but mighty cleaning crew working around the clock to keep things pleasant.
Additionally, these tabs are eco-friendly, which is a huge plus for anyone who loves the great outdoors. They’re formulated to be safe for septic systems and the environment, so you can use them with peace of mind, knowing you’re not harming the beautiful places you visit.
Finally, let’s talk about the cost-effectiveness. These tabs are affordable and come in bulk packages, meaning you’re well-stocked for multiple trips. The value for money is excellent, given the convenience and efficiency they provide.
In summary, RV toilet sewer treatment tabs are an essential addition to your RV supplies. They simplify tank maintenance, eliminate odors, and are environmentally friendly. For anyone who wants to make their RV experience as pleasant and hassle-free as possible, these tabs are an absolute must-have. Happy travels!
