Happy Campers Extreme RV Holding Tank Cleaner

As a lifelong RV owner and now a full rime RV resident, I have used nearly every commercially available chemical. I spent years perusing the Walmart shelves and even the local RV shops. I accepted the fact that tanks stunk. and it was just a by-product of the RV life. One RV that I had was particularly aromatic when opening a valve or driving it down the road. I started looking for something else. Perhaps there was something better.After a little research, I discovered the flagship product called "Happy Camper" Without exaggeration my tank odors were a thing of the past. Nothing. Zero. Unbelievable. So then I tried the "Extreme Cleaner" Now I end every season by cleaning all of my tanks. My gauges work, the odors are gone. Everything flushes EVERY TIME. I have not had a clog since using their products.All in all. I will never put anything else in my tanks BUT Happy Camper.

Have to admit Hubby got a little lax cleaning the holding tank of our 10 year old RV. The black tank gauge hasn't worked in years. Finally this summer it got to smelling, and I went looking for a solution to the problem. Hubby was skeptical, but willing to try. Used this cleaner according to directions, except hubby did not do the wand wash out routine. Filled the tank 1/2 full and took a 3 hour (planned) drive. Then filled the tank the rest of the way and let it sit for 3 days. Dumped it. No tank odor and my gauges work!! I am going to keep this product on hand to be sure we don't get so far behind on this maintenance ever again. It was so easy, I am sure Hubby will have no problem keeping up with it.

did what was advertised

This is a great addition to keep your RV Black Tanks cleaned out and running smooth. One use and we were operating like we were brand new. So happy we purchased this and used it. Great product and easy to use.

This product is worth the price. I have tried multiple products and this one is the best. Hands down!!!!!

I decided to purchase this extreme in hopes that it would make a huge difference. However, it really did not so I will probably continue purchasing the regular happy camper that I have been pleased with. Mainly because it is a little bit cheaper.

I was having issues with RV blank tank not emptying and I decided to try Happy Campers Extreme cleaner. I am currently stationary and followed the instructions accordingly. Mixed the Extreme product with 3 gallons of hot water until dissolved, poured into the toilet, then filled the tank with the blank tank wash connection to help provide agitation, as recommended by Happy Campers. Then let sit for 24 hours. I opened the valve, turned on the black tank wash and emptied black tank 100%! Sensor light indicated tank was empty. Happy Camper for sure!

Works exactly as it's supposed to, well worth using a few times per year for a deep clean of your black tank

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

Use it to get the trailer tanks clean

works great

Didn’t work. Nothing to return as it’s a one time use. Ice cubes in the black tank did the trick and we only had to buy 2 bags. Save your pennies.

I did not find this worked at all. My father and I both bought one and neither of us were happy. $100 down the toilet, literally.
