Thetford Eco Smart RV Holding Tank Deodorant - Waste Digester - Detergent - 36 oz 32949

Easy to use and not a strong scent. Just enough.

We use this product all the time in our porta potty. It controls the smell. We reorder often. I would recommend it to anyone that uses a porta potty.

This is a very nice tank deodorant if you like the smell of Christmas candles while using the toilet. But it doesn't seem to actually neutralize or break down any waste over time, as the stench when dumping is unbearable. I switched to a blue chemical for the tank and am using up the green stuff for cleaning and rinsing afterwards. Also the dispenser part of the bottle is much too easy to just "keep on pouring" out the contents well past the small measured amount you thought you were using. Oh and it came unsealed and leaking as with other reviewers.

It’s good stuff just didn’t work as I thought it would in our out house it only lasted bout a day but during that day left the out house smelling very pleasant arrived promptly and only damage was on one child proof cap it was cracked in half but inner foil seal prevented leak so that was good !

Used in camper potty in our tiny house. I like the smell and it does a good job of controlling the odor.

Smells really clean and keeps tank fresh! Used this since it first came out - don't flush TP, and keep water in black tank. Great is sink traps also to leave a fresh smell in your RV or boat.

Thetford has replaced its Supreme Green tank deodorant with EcoSmart. I can only assume, but don't know for sure, it must be because of environmental reasons because no one could possibly feel this is an improvement! EcoSmart has a peculiarly unpleasant smell to begin with - kind of perfumey - and when it mixes with what's in a head, well, it's beyond gross. Plus, it has no staying power. You can use half the bottle at a time and within a day, it's as if you added nothing to the tank. On the other hand, I'm not sure I prefer the EcoSmart to an untreated head - I guess it's the choice between wondering what that horrendous smell might be or knowing what it is...Our holding tank used to be a non-issue when we used Thetford's Supreme Green. Now, we've got a real problem. If anybody knows of a better alternative, please let me know!

This product works great - and it doesn't rely on formaldehyde or other such chemicals - which are bad for the environment. This is an excellent product.

Used as directed portapotty is odourless for weekes on end if you forget to empty it

Works great - and no guessing with the convenient measuring dispenser !

Use in my shop chemical toilet os low odour is important as is indoors.
