I have tried all the major name brands in my 5th wheel and none work as good as this at keeping black tank odors unnoticeable. Even in hot weather.

<p>I have used many RV septic products and sold thousands of RV toilet products. Once I tried Bio-Kleen- Kleen Waste, I found the only product that not only broke down the solid waste, but the the Michigan Cherry scent was very nice smelling and not like the formaldehyde smell most RV products are like. Best product to date!!</p>

Keeps camper fresh and clean smelling year around even closed up for 3-4 months of winter down time.

We were introduced to this product at our marina, to use in our holding tanks on our boat, we loved it so much that we also have purchased it for our travel trailer (full time RV'ers) it works great even on those 100 degree days of the summer!

I have used this product for over 2 years and have great success. It does a good job at covering odors during all temps.
