Walex Commando RV Black Holding Tank & Sensor Cleaner - Eliminates Waste & Paper Buildup, Restores Sensor Function, Lubricates Valves & Seals, Advanced Enzyme Formula; Dissolvable Packets, 4 Count

These are great for cleaning the black tank out. I really appreciate these. Read the directions. Use as it says although I usually put the pod in the toilet, add HOT water so the stupid skin from the pod dissolves. And then fill the black tank up. The pod skins are disgusting and I don’t use pods for anything but this brand only comes in pod form. It works. Bubbled up. Gets the chunks out.

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.

Loved it

I used the Walex Commando Liquid Black Holding Tank cleaner and it consistently dissolved the waste build up in my tank as the product described. It left a very fresh scent, which is wonderful for a small RV bathroom.

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.

New to us camper was having issues with false readings on black tank. I see the cleaning port on the side of the camper along with the the back wash attachment on the drain. Bought a pack of this and filled my black tank to the top and tossed a pod in. Let it set 2.5 days and all is good. The sensors now worked and helped with a small odor.

Our sensor quit working g and this helped clean it off and works great

Good product, does exactly what it says on the tin

is what it means

Despite using tank cleaning drop-ins regularly and using the tank flush, we would consistently a 1/3 full reading immediately after emptying. We dropped one of these into the tank, filled per instructions and let the solution sit for approximately 12 hours. Emptied and tank flushed again and after a moment or two, the tank indicated as empty so it worked perfectly! The only think I wish is that these RV necessities would be less costly - on a cost per use basis, we are paying just over $4 per drop-in (after tax). True, you shouldn't need to use them very often but that's still a lot. They do work though, so I guess my mindset should be that you get what you pay for.
