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.

Prevents any order from developing from the grey tank residues. Keeps the grey tank smelling nice for long periods with simple treatments.

good nice smell
