CamcoTST MAX RV Toilet Treatment Drop-INs - Control Unwanted Odors & Break Down Waste and Tissue - Safe Septic Tank Treatment - Orange Scent, 30-Pack (41183)

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!

These RV toilet drop-ins are super convenient—just toss one in, and you're set. They control odors really well, even in hot weather, and help break down waste and toilet paper. The scent is light and fresh, not overpowering. Plus, the individual packets are mess-free and easy to store. Great product for hassle-free RV maintenance!

In our van build we use a cassette toilet, one of these dropped down in the bottom works wonders, no smell for weekend trips. Not only is there no smell, but there's a pleasant smell coming from the toilet now-I never imagined those words coming out of my mouth. We usually dump every third or fourth day depending on where we are and how much we've used it. This are a must for us at this point now, no more stinky toilet.

Not the greatest but gets the job done. If you are looking to cover up foul smelling black tank, this is not it. These are more for the in between dumping and filling when the camper is stored.

Has done its job for us on our fifth wheel! Will continue to use to treat our black tank.

This product leaves our RV smelling fresh everytime! It is effective, works great, and stores perfect!Orange has been the best scent so far!

These work great, fair price and fast delivery.

Product was broken open and several of the drop in packs were open and leaking all over the container and inside the shipping box. We’ve used this many times before and it works well when it’s not damaged before even using.
