ECO-SAVE Holding Tank Product - RVstuff.com

Model:

ECO-SAVE - DRY powder is ecologically safe bacteria/enzyme based product for holding tanks and septic systems. No longer a need for you to put up with that old chemical odor in your unit. ECO-SAVE DRY powder will keep your tanks clean, valves lubricated.

I first started using Eco-Save in 1996 and have used it in two 5th wheels that we have owned since then. When we were full timing, I used a different product in the Winnebago, available from the RV Stores.
