"RV digested plus works great as long as I use two tablets after each tank emptying. . if I only use one tablet the older gets pretty strong after 2 days, with two tablets I empty on the 7th Day."
"Love the product and that it doesn't use harmful chemicals."
"We have been using this product for several years and have never had a problem. Will continue to purchase this"
"Quick delivery. The only product we use."
"Neat, non-smelly treatment that dissolves completely and rapidly. First pod I dissolved in a cup of water first just to make sure! Happy that it won’t spill in my boat locker. Started with a single two-pack along with the black tank cleaner, the de-clogger and the toilet cleaner. Everything seemed to work well. Time will tell. Am going to order more pods."
"These pods are great particularly for a full timer. They're pretty much the same organisms used in septic tanks so no worries about possible chemicals wrecking that ecosystem and causing some real problems if that's what you hook up to. The biggest relief is being able to expand beyond RV only toiletries without worrying about an impacted tank, if a product is septic safe it's safe for my rig because I effectively have a septic tank under my floor now."
"After your all hooked up at your campground drop 1 pod and flush adding extra water to tank. You can't get much easier than that. I also use the toilet bowl cleaner just before we drain and unhook. Haven't had any smells since we started using your products."
"This is by far the best and easiest product we have used to date."
"These are convenient for our rv. It is parked permanently in a rv park. Not being moved it is difficult to clean. We found the Clean- It worked great. It finally cleaned our tank completely."
"I have been using the pods in excess of 9 years. They are so convenient for the toilet dissolving and premeasured."
