Black Holding Tank Cleaner

Worked as advertised on black water tank. Gauges started acting wonky, added product, drove to next campground, voila, gauges now working well!

So we bought a travel trailer third-hand. We believe the black water tank was emptied before it sat up for the past year, but not cleaned out in any way. So we've been having to force down waste for a couple weeks. I searched online for a solution because the regular black water tank treatments meant to dissolve current waste and toilet paper weren't helping at all. I used a method described by others online, putting hot water with dishwashing liquid into the tank. I even added baking soda for some softening and slip. That caused a rush of gunk to flow out and resulted in a really awful stench (I guess it got some of that old stuff moving!), but still stuff was clogging near the top. Maybe doing it again would have helped more, but I went ahead and bought this product after reading the good reviews. Well, we emptied the tank again (or so we thought) before replacing the toilet. After removing the old toilet, we realized the tank was clogged again and the waste was almost to the top. I opened a Commando packet and poured it right in. I cleaned up where the old toilet sat, my husband installed the new one, and I checked the sewage level with every flush expecting that at some point it would go down. About 6 hours later, I noted that the level had gone down some. It was still pretty high up, but that was progress, and I knew it would take longer. Well, I just checked again. It's been 20 hours since I poured the packet in and I was shocked to find that not only is the waste too far down for me to see it anymore, but I can see sunlight coming in through the tank walls. I don't see one bit of gunk stuck on it either and the stench is gone. My gosh, this stuff really works, and it only took one application. Keep in mind that we throw away most of the toilet paper (all from #1 but not #2), so it's not overburdened with toilet paper--at least not from us. Expecting more of an issue, I actually bought the bucket of 40 packets and I was expecting to use one a week. I'll see how it goes, but I may not actually need this many after all. I do not regret the purchase at all though.

Have used this product several times as directed and it seems to help clear the black tank, but not completely. It could be a bad or stuck sensor that will not clear.

Worked as described! Black tank in my 2012 5th wheel camper always showed full. I filled the tank up with water and dropped one packet in the toilet. Waited 5 days and drained it out. BOOM now my tank sensor is reading empty and seems to be working great! Definitely worth the money!

We used this product after a year of black tank readings indicating full after emptying. It cleaned out the tank and sensors now indicate empty!

This didnt help any faster then the regular flush out with water trick until water is clear. To me, both worth the extra money, but it smells nice.

Great stuff, works like a champ to clean out tanks.
