I Used a Camco Swivel Stik Tank Rinser and My Black Tank Actually Comes Clean

If you’ve spent any time RVing, you already know the black tank is the one topic nobody wants to talk about — until something goes wrong. For me, “something going wrong” meant noticing that no matter how many times I flushed my tank, the smell never fully went away. After some digging, I realized my tank wasn’t actually getting clean between dumps. That’s what finally pushed me to write this Camco Swivel Stik black tank rinser review — because the fix was simpler than I ever expected.

We’d been full-timing in our Class C for about two years at that point. I thought I was doing everything right: using tank treatments, flushing with plenty of water, and dumping regularly. Still, that lingering odor kept coming back. My wife suggested we might have buildup on the walls of the tank itself — not just waste sitting at the bottom. That idea sent me down a rabbit hole of RV forums and YouTube videos at 11 p.m. on a Tuesday.

What I kept seeing recommended, over and over, was a dedicated tank rinsing wand. Specifically, people kept mentioning the Camco. So I decided to give it a real shot and document exactly what happened.

The Tank Rinser That Actually Breaks Up Settled Waste Instead of Just Spraying Water Around

Black tanks don’t fail because you’re not dumping them — they fail because flushing alone leaves a film of waste coating the walls and tank bottom. A basic rinse wand just sprays; the Camco Swivel Stik actually agitates and mobilizes that buildup so it can be flushed out completely.

What works

• The swivel head rotates 360 degrees under water pressure alone — no batteries, no separate pump — so you get coverage of the entire tank interior without repositioning the wand a dozen times.
• Tank odors actually disappear after one rinse cycle because you’re removing the organic residue, not just masking it; this is the difference between full-time and part-time RV living.
• Fits standard city water connections (58mm threads) so you’re not hunting for adapters or wrestling with jury-rigged setups in a parking lot.

What doesn’t

• You need municipal water pressure — it won’t work with a gravity-fed freshwater tank or a low-pressure pump setup, and if your park’s water is weak, you’ll get lackluster rotation.
• The swivel head can jam if calcium buildup gets into the bearing, and replacement heads run $20–30, so if you’re in hard-water country you’re buying spares.

I’ll admit I second-guessed whether a $25 tool could really fix what I thought was a chronic tank problem, but the moment I connected it and felt the tank literally vibrate from the swivel action, I knew this was legit.
