Aqua-KEM Original - RV Holding Tank Treatment - Deodorizer - Waste Digester - Cleaner - 32 oz - Thetford 09852

I love this product and I’ve been using it for years. Its concentration allows for efficient. Use in my black tank and works incredibly.

There is a reason formaldehyde toilet chemicals have been around since the dawn of the chemical toilet. THEY ARE THE ONLY ONES THAT ACTUALLY WORK! I’ve tried all the others in my 5 gallon portapotti camper tank. The tank stinks after a day. “Old blue” this age old thetford formaldehyde chemical is the only one that truly breaks down the solids and neuralizes all odor. All the so called experts that make the other stuff will tell you formaldehyde is bad for septic systems so you have to use formaldehyde free. So I tried the others for a while. One after another I found over and over they didn’t work. So I got to thinking, of formaldehyde is so bad for septic systems then why are there now massive signs at every rv Park saying no dumping if formadehyde chemical is used. I’ve never seen a sign like that. So I did some research. Formadehyde is actually biodegradable. And thetford has a patent on this chemical. So all the others trying to get you to worry about formadehyde are just lying to you about the horrors of formadehyde because it’s the only way they have to compete. Just buy this and say good by to clogged pipes and tank smells. Tried and true. Been around for decades. The only one that really works.

Aqua Kem USED to be a great product. It completely got rid of rv toilet smell. Somehow they've changed the product and it no longer reduces the smell. I'll assume since they are in California they were regulated out of whatever they used that worked. But they kept their look and changed their name to AquaMax. I don't know why Amazon is still using their original name but it's very misleading. AMAZON check your product spelling!

One of the best black tank deodorizers available. We try others and keep coming back to Thetford.

I think this product does a great job in our trailer. It keeps the odor where it belongs.

This was the blue stuff that works.

Manages odor very well. I had used it before, then couldn’t find it in the store, so I used another inferior product. I knew I had to find this product again! It’s the only one I’ll use in my portable potty.

Had to live in an RV for 6 months while house was being built and the toilet was the single most stressful annoying part of it all! Clogged toilets and stale water smells was enough to go insane. I read rv blogs and articles and several recommended this product so I found it on amazon and it worked! It was the only thing that worked. Other stuff I bought just did nothing. I put this in the toilet and sinks for the water smell which helped immensely and for the clogs it took care of it overnight. The hot water trick didnt work for me...at all. This stuff really is amazing especially if you live in a trailer. Those toilets are too sensitive but this should take care of anything.

Je suis très satisfaite. J’adore ce produit.

Le meilleur produit pour les bassins de black de roulotte tout est détruit

Haven't used product yet but package arrived intact. I checked scent and should work fine in my new Thetford portapotti when I launch.

Really works

While I realize its suppose to be powerful - and I guess the smell is supposed to overwhelm any bad odours - the chemical smell this has is overwhelming, it stains when it splashes. Next time I will use something that doesn't smell like the inside of a chemical vat.
