Review: A must have for your RV grey water tank - 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.
Review: Use Regularly, Works Great - 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.
