Camco TST Lemon Scent RV Grey Water Odor Control, Stops Sink Trap Odors, For Use In Drains, Sink Traps and Waste Vents, Treats up to 16-40 Gallon Holding Tanks (64 Ounce Bottle) - 40256

Works great to eliminate order in your grey water in our motorhome. Love the lemony smell, it smells clean not like a chemical smell

I always use this when I take my trailer camping. Many people forget to treat their grey water when they go camping and only add treatment to the black water tank. It is necessary to make sure the grease breaks down and doesn't sludge up the tank. It also keeps the smell down. I recommend using more than the dosage recommended on the bottle. I use about half a bottle when I go camping. It is cheap insurance and worthy preventative measure that can save you money in the long run on tank cleaning fees. It is super easy to use, pour it down the sink and add some water. It is very effective at keeping your tank clean.

I have used both the powder and the liquid. Never had a problem with smell. I would recommend this brand.

We live in our RV fulltime and use this product regularly, especially before moving our motorhome. It works exactly as advertised — no odor problems at all. Easy to pour, effective, and gives peace of mind while traveling. Definitely a must-have for RV owners.

We have a seasonal lot for our RV so we use it on weekends. When we leave, we empty our tanks and then they sit empty all week in the heat. The tanks can smell after a while so we bought this and used after opening after winter and will use again mid summer. Used it last year and it really helped!
