Performs as advertised Does an excellent job at cleaning black and gray tanks. No more issues with sensors

My friend was "gifted" an RV that had brown cement in the tank. You could see it. Overnight, this made it possible to get it cleaned out. Had to chop at some chunks but, this obviously helped. You don't want a video ....

Worked well as a temporary partial solution to holding tank sensor problems. But no substitute for a professional cleaning, Like most RV owners, I thought when I drained my black water tank all the nastiness drained out - until I had a professional cleaning and discovered how much disgusting stuff had been lingering in my tanks just under my dining table! Advice for RV owners - even if you have full connections, don't open your black water valve until your tank is at least 2/3 full. If it's not 2/3 by the time you are ready to break camp, just add water to the toilet until you get to 2/3 or more and then open the black water valve to drain. I close my gray water valve the day before breaking camp so that I can open it after draining the black water to flush the drain hose with the gray water. Otherwise, if you have the valve open, when you use the toilet, the liquids drain out immediately leaving the solids (toilet paper and poop) in your tank . And then come the sewer flies whose larva turns into worms and just becomes more and more disgusting! (This only takes a few weeks.) Have your tanks professionally cleaned at least once per year if you use your toilet for #2! Between professional cleanings this product will help. When using this, it's best to put it in the toilet with water before you head out on your journey and the drive will "slosh" it around in the tank to help with scouring. Then drain the tank before setting up camp.

Great

It works OK ,but in no way is it worth the price. You can get better for less.

Love this brand and feel safe using it

My black tank sensor stayed at the “Full” level since last year. I didn’t care too much about the sensor as it happens to any sensor. I use a variety of black tank cleaners/treatments on every dump. As I was going to order another happy camper, this extreme cleaner came up and I wanted to give it a try. Used 5-6 gallons of water and drove for 1 1/2 days and let it sit with full water in black tank for another day. I was quite excited when I was about to dump the black tank. Well, I didn’t see much of gunks and my sensor is staying at Full. I am obviously not convinced due to lack of evidence and it is too expensive to try again.

It did exactly what the company said it would do.

Se nota que limpia algo, lástima que sea sólo 1 uso y que sea tan caro.

Follow the directions. I left this product in for two days. Black water tank in boat. Did a great job.

hope it works

Use it to get the trailer tanks clean
