I used the tank and sensor cleaner on my tank and left it for
24hr. the sensors are reader empty now and it smell great to.
I would recommend this product.

Great product. Works like it is advertised

Black tank showed 2/3 full even though emptied. Used this product as directed and black tank shows empty again. Will definitely use this product again.

Tank cleaner

I would say it works pretty good for helping clean out your black tank. I would use it probably once a year or so. I filled the black tank half way with fresh water and a bottle of the cleaner then towed it a good distance and then let it sit a few days. When I dumped it it was very dirty and prior to putting the cleaner in it I rinsed it several times and even completely filled and dumped it and it was as clear as could be so it definitely cleans better than what you can do by just rinsing.

Best tank cleaner ever!

We have used a couple of different tank cleaners. Our sensors have not shown empty in 3 years. Finally tried this cleaner and let it soak for a week, because gotta go to work. My husband was finally able to dump and rinse today. And we have sensors reading empty!

This stuff was very effective. The smell is natural orange and it really did clear my tanks well.

Used TST, Unique, and another, but this brand keeps the tanks smelling better than the rest and I never see solids when I dump the tank. Impressed.

I've used this product for three outings now. Granted, I haven't yet put it to the late Spring heat test here in AZ. However, thus far it has worked well at controlling odor from my tank and it really does seem to hold to its namesake of liquifying solids.

we've tried everything, this stuff works, through looking, found it!!


Love this stuff, works great and I feel confident after many uses it'll continue working. I've never had an issue with the black tank while using this.
