Finally, an RV Toilet Treatment That Actually Works!
I’ve been using these Camco TST MAX Drop-Ins in my RV for a few trips, and I’m honestly impressed. The orange scent is pleasant — not fake or overpowering — and it actually keeps the tank from smelling up the bathroom between emptying. I’ve tried other treatments before, and most of them either fade too fast or don’t break down the waste and tissue well. These are so easy to use — just drop one in before a trip, and I don’t have to worry about odors or clogs. It’s made my RV trips way more pleasant, and even my kids noticed how fresh everything stayed. Definitely going to keep a pack handy for every outing!

Pleasant orange scent and it treats the septic system... BONUS!
We actually purchased these after a fellow RV camping neighbor/friend recommended them. I am so glad they did! The orange scent is pleasant but NOT overwhelming (which we appreciate). The scent lasts for about 3 to 4 days then starts to fade by about day 7. This is perfect for us because we hardly camp for more than 10 days... usually 5 days, on the average. We have never had any septic issues. But knowing that these also treat the septic tank and help break down tissue and gunk is a complete bonus!

work good and good Price
They work good. But not as well as the blue ones when it comes to hot weather and depending on how long your black tank sits. But I have to say overall they keep the smell down. If you’re not in a very hot environment these work very well. During the hot summer months you might need to switch up to a stronger pack. Or maybe double up packs but thats not very cost effective. I am also looking for cost effective options.

Camco TST MAX Toilet Treatment Drop-INs – Great for My Camp Toilet
I’ve been using these Camco TST MAX Drop-INs in my small camp toilet, and they work great for keeping things fresh and functional. The 30-pack is perfect for my weekend camping trips—each packet’s a little brick that I toss into the tank after a dump, and it gets to work fast. I’ve got a basic portable toilet (about 5 gallons), and one drop-in handles a full day’s use for two people, breaking down waste and TP like promised. No clogs or sluggish flushes so far after a dozen uses. The orange scent is a big win—it’s strong enough to mask any stink without feeling like you’re sniffing a citrus air freshener factory. I was worried about odors in tight quarters, but these keep the tent trailer smelling clean, even in summer heat. They’re septic-safe too, which is clutch since I sometimes empty at campground facilities—no guilt there. The resealable bucket keeps them dry and easy to grab on the go. A couple notes: the orange dye stains the water a bit, which isn’t a problem but looks odd at first. Also, they dissolve quick—great for action, not so much if you’re pre-treating and letting it sit too long before use. Compared to liquid treatments I’ve tried, these drop-ins are less messy and more convenient, though you’ll burn through them faster in a bigger RV tank. For small camp toilets like mine, these are spot-on—effective, odor-busting, and hassle-free. I’d give them 4.5 stars, rounded up to 5 for how well they fit my setup. Toss one in, and you’re good to go!

Not the best of scents for an RV Toilet Tank
I 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.

Need better shipping method.
The product is good. The delivery was not! The container was placed in a paper bad and miss handled causing several of the packs to break rendering then useless.

Si funciona, no permite olores y es súper fácil de usar en el baño portatil. Tengo dos pequeñas y se agradece tener este tipo de productos al salir a acampar.

Easy to use, maintains the smell and breaks down the solids. Also easy to drop one little package into the toilet to circle.
