BiokleenM01709 Kleen Waste Holding Tank Treatment - 1 Gallon, 128 Fl Oz (Pack of 1)

Smells good. Use this in Black Tank. Helps with break down and odor. Especially in summer months

Kills the smell and it last with just a little bit.

I liked this product, I just like the tablets better.

Easy to use, helps diminish odors in our Prevost bus, but still emits a funky smell which could be covered by an added scent.

Good stuff! Very thin and unimpressive to look at but it smells decent and controls odor much better than all the products I’ve tried from Walmart and camco or thetford. I’ve held off giving this a five star review because I didn’t want them to raise the price so hopefully they keep it reasonable.

I ordered this product thinking from description it would be super concentrated. I was disappointed that it wasn't. The recommended 4 oz. to use would not do anything and had to use almost a half gallon to treat my portable toilet. So, I will get two uses out of this gallon. Not worth the money and the portable toilet service that cleans it out refreshes it after emptying it with a much better product. The entire service is about the same cost as this gallon.

We’ve used this for 6 months in our rv toilet. We t smells very nice and works well thank you b

Wasted a lot of money on different products until we found this one. I always would get a funky smell in our RV tank no matter what brand enzyme cleaner we used . We bought this at an RV show and couldn’t be happier. NO MORE STINKY. On your first application it’s important to empty your tank, refill with water and put in an initial 4-8 ounces. Let it set for 24 hours. It not only cleaned the tank better than everything else but the sensors now work. This gallon will last a while. We were so happy with this product that we tried out other products in their line and have not been disappointed yet. As long as they continue to make a product that actually works we will continue to be a customer.
