The Extreme Holding Tank Cleaner by Happy Campers is just that — Extreme!
Use this product when you need to totally clean an RV or Marine holding tank. Works for both black water and gray water holding tanks.
This is NOT a regular maintenance treatment to control odor, this product is designed to completely clean your holding tank when you know youve got a problem. If there is stubborn buildup, mold, or other disgusting gunk in your holding tanks, this will get it out.
We highly recommend that you watch what comes out of your holding tank even if you thought it was fairly clean — youll be surprised.
Just take a look at these actual images shown above of an RV gray holding tank that appeared to be clean. The water was running clear before using the Extreme Cleaner treatment and WOW, look what came out.
Make sure you empty what you can out of your RV holding tanks before starting.
Mix the product until its fully dissolved and then pour it down a sink or flush it down the toilet.
Add 5-7 more gallons of water, then drive for a minimum of 45 minutes (or until you reach your destination). Then dump and rinse your tank.
*If stationary; fill your tank and let it set 24-48 hours before dumping.

Much like clothes in a washing machine, rinsing & agitation does most of the work, EXTREME CLEANER simply softens & helps dissolve sludge & crud in holding tanks. Use an on-board or flexible down-the-toilet rinser for best results.
If your trailer/RV is not mobile:
Fill your holding tank as full as possible and add the entire container for treatment following step 3 above. Leave in your holding tank 24-48 hours before dumping.
Note: If you own an RV you probably know that holding tank sensors are historically temperamental, and even a little unreliable. Heavy cleaning will usually (but not always) restore scum-crusted sensors. Stationary units require more rinsing with less success. Will not dissolve “wipes” or fix broken or corroded probes.
*This product is not intended to be a regular holding tank treatment or deodorant - seasonal at most.
