Eco Smart Enzyme RV Holding Tank Deodorant - Waste Digester - Detergent - 36 oz - Thetford 32947

Works as well as the drop ins

Love. Easy to use. Helps keep things clean and fresh. Fast ship

The fragrance is not too strong or offensive.

The label definitely states NOT to use in recirculating OR portable toilets. Why I do not know. Very disappointing that this was not in the item description. Liquid enzyme products are usually ok for portable toilets if not recirculating toilets. Bummer...

Neither the orange or the green worked for me in my cassette toilet. After a day, odor came back. After adding additional doses, still not working well. Going to try the "Odorlos" brand and see if there is an improvement. I would not buy the Thetford again.

THis product did not control odors in the holding tank! I added extra twice to the tank and it still stunk.

This product for use in my composting toilet was simply ok. In an RV tank that is dumped every few days it would probably work great. The odor control over 3-4 weeks does not hold hence I used more of the product than label directed.

It’s not that effective of an deodorizer !! I use a porta potty for urine use only and it smells dreadful after 2 days ! Disappointed in this product
