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