Review: Reliable odor control for camper tanks – a repeat buy for us - We’ve been using this in our camper grey water tank and have had good results so far. It helps control odors and keeps things smelling fresh, especially during longer trips. It’s easy to use and doesn’t have an overpowering scent, which I appreciate in a smaller space like a camper. Overall, it’s worked well for what we needed and we’ll continue using it.
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.
