Walex Commando RV & Marine Black Holding Tank Sensor Cleaner - Ocean Mist Fragrance - 4 Treatments

I reside full time in a small RV; step on toilet flush peddle — water runs and opens toilet hole flushing to black tank, drop one pod in toilet hole followed by hot water (I boil water in tea kettle), I “clean” monthly, instructions says less often. let pod work its magic for several hours or overnight to break up solids. Then, do black tank drain to sewer/septic… Tada!

The worst part about camping are the holding tanks! Commando is the best tank additive! We use it regularly. It makes camping smell so much better.

Our trailer sensors in the black tank have not been accurate. Followed directions and Bingo. We got a reading of 0 when the tank was empty!

I was skeptical when I ordered this. I left it in a full tank for two days. After I drained it I checked the gauge and the sensor worked for the first time in two years!

I have tried a multitude of black holding tank products and Walex is the best value I have found. Their products smell good too. Many of the products on the market don't clean sensors or lubricate the valves. I use the cleaner about once a month because we stay in ours where he works.

Easy to drip into the black tank and let it do its stuff.

I've used 2 packs and followed the instructions and it did NOT get rid of the odor.

Did not work as well as other brands. Had to use 2 to keep odors down. Not cost effective.

Didn't clean sensor or tank very well

I ran 3-4 pouches of this through my tank, letting it sit in the tank for many days longer than recommended, but it just didn't work.
