Worked perfectly

“Was having tank odors even though we were cleaning regularly and this fixed it”

It worked on wet naps

“We had some wet wipes go down the RV tank. I poured this in and left it for 2 days. I use a macerator to empty and those wet naps kept clogging it. No problems at all after using this”

Recomend for clogs and cleaning sensors it really works!

“...when it comes to cleaning the black tank I put it in right before I have to dump the black tank and it does its job and I only have to flush black tank once or twice instead of having to do it a million times to get it clean”

Great space saver

“This toilet brush is great and since it is flat it takes up very little room in our trailer. We used the holder behind the toilet and it works great. It was easy to assemble.”

Worked great for us on high iron water stains.
