- SnapshotToilet treatmentUse for camping. Bought before and over time the packets burst. So we just poured in certain amounts and finished. It out. But it does work well and keep the odors away.
- Choestoe ValleyExcellent ProductWorks great, and the only treatment I recommend. Easy to use packets that you just drop in the sink or toilet.

Living in a trailer, the toilet situation can get real real, real fast. These Drop-Ins are the only thing I’ve found that actually control odors instead of just pretending to. One pod, drop it in, and boom—no more worrying about funky smells creeping through the whole place.
They dissolve fast, keep everything fresh, and help break down waste the way they’re supposed to. I’ve tried cheaper brands, and trust me, I won’t cheat on these again. The difference is night and day.
If you want an RV bathroom that doesn’t betray you the second the weather changes, these are your new best friend. - Hubswork good and good PriceThey 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.
- BigBKeeps the stink down.Best I have found. smells good. easy to use pouches. perfect size. Package reseals well to help additional drop ins from getting humidity in them and falling apart. Great cleaning and breaks down the POO well.
- L. E. D.Camco TST MAX Toilet Treatment Drop-INs – Great for My Camp ToiletI’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! - Jimmy ODoes the job !This product works great.
I live in my camper for months at the time due to work. I've tried other "copy-cat" drop-ins and none compare to TST Max.
I use 2-3 drop-ins each time I flush the tanks and do not have that sour RV odor that most campers have. - Carol LeeSmells good, works great!This is the only product I use in my RV black tank. It keeps the tank clean and odor free all summer. It smells good and doesn’t damage our tank. Highly recommend!
