  • Porta-Pak
Scent: Fresh
Really good stuff. I use in my portable toilet which has a 5.8 gallon waste tank. I use one drop in and was surprised at how good the odor control is. If you own a portable toilet or camper with a holding tank, this stuff works great. Very happy with this product.

  • My bathroom actually smells fresh now!
Scent: Fresh
**2025 edit** Just ordered some more of these, I bought the last bag in August of 2024. I didn't really use them throughout the winter because it was cold enough that they weren't needed, we weren't having any odor issues. But it has started to warm up some and the smell hath returned. I had 3 packs left after winter and just put my very last one in. I'm still just as thrilled now as I was when I first got them, I don't know what's in these but they definitely help eliminate the black tank stank! i ordered one pack of each scent, I am eager to try them all out. I would also like to add that I do NOT put toilet paper in our tank and we also have a bidet (which = more water in our tank vs just flushing) so I'm not really sure how much that changes the equation, but for us they most definitely work! ------ When I first got my camper friends and family told me not to even bother with the packs because none of them worked and were a waste of money. After trying many different kinds I finally gave up and went with the "dawn and fabric softener" approach that everyone said worked better than packs. While it did work better than most packs it was definitely expensive and there were still smells. I've been full time in my camper for almost 3 years now and I had pretty much given up hope. I started getting desperate and used Bleach in the tank when it was really bad, but it still smelled horrible after a day or two. I was so impressed one day when I visited a fully loaded port-a-potty in the 100+ degree heat that had zero odor that I started trying to figure out what they put in port-a-potties because I was going to find a way to order some lol. That is how I stumbled across these packs and saw the great reviews. I decided to give them a try and low and behold THEY WORKED. No more black tank belch when you flush! No more stinky bathroom! No more black tank air (un)freshener wafting through my camper! No more sewer showers from my fan sucking the stank out of the tank while I'm showering! I am so so so thankful I found these! It seemed like no matter what I did, how often I dumped my black tank, no matter how much tank flushing I did, or what I put in the tank there was always an odor in the bathroom. ALWAYS. There was even odor outside the camper coming from the hose and septic. I literally could not take it any more. When these first arrived I wasted no time adding one to my tank. I had just emptied the black a few days prior but added one anyways. I still had marvelous results. There was some odor in the camper when I emptied the black tank, but it was probably 1/4th of what it usually is. After I dumped the black I immediately added a pack and put several gallons of water behind it. I have had ZERO odor with the 2nd pack as well. I am patiently awaiting the next dump day to see how good it will work at keeping the odor at bay during a dump this time since I started off with a pack instead of adding a pack to an already stinky tank. I am just amazed every time I go in the bathroom it actually smells fresh and clean in there instead of stinky. This is the first time that has happened in almost 3 years. I am so very happy. I'm eager to try the other scents and see if they work just as well. It hasn't been over 100 degrees since I got these packs but it has been in the high 80s and lower 90s, I am hoping they perform just as well in the intense heat as they have so far. But regardless, to have at least gone this long in the summer without having to smell black tank stank is a win for me. I will definitely be ordering more! ... show more

I use these all the time in my RV septic when I'm not at full hook ups and need a break down product. Seem to work well and makes complete dumping much easier.

  • Easy to use and smell great!
Scent: Lavender Breeze
I go through a bag of these and the commando black tank cleaner in 4 -6 months. We are full time 5th wheelers right now. We have an extremely large black tank and just let it fill. The color is pleasing. The freshness is amazing. Love the smell! They are so simple to use… just plop in the toilet (we let it dissolve) and flush. I add one of these and one commando every month (at separate times) until the bags are empty … then wait another month and empty. Love these things - keeps any unwanted smell at bay. We don’t throw toilet paper in our tank (anymore) due to many issues with our past campers. If you’re looking to clean your sensors , I can’t speak to that. We’ve had no luck in that regard with any product. Besides , I don’t believe these are for that at all. Anyways, we love all wale x products! Highly recommend to keep the tank smelling fresh! ⭐️⭐️⭐️⭐️⭐️ ... show more
