EXTREME CLEANER for RV & Marine black/gray waste holding tanks:

USES:
1) Cleans poor working sensors.
2) Softens & removes solid buildup.
3) If your present tank treatment has quit working.
4) You just bought your RV & want to super clean the tanks for a fresh start.
5) A great product for an annual clean out, especially when winterizing.

Recommended for use in 30-60 gallon tanks. 100% Satisfaction Guaranteed!

USAGE: Happy Campers Holding Tank Treatment

1 Scoop Treats up to 40 Gallons

1) Prime holding tank by adding 1 gallon of water.

2) We recommend using a bucket or container to pre-mix by slowly sprinkling one scoop of HC while stirring into 1 gallon of water. Once product is suspended in water, then flush that down the toilet or pour down sink.

3) Lastly Add 1 more gallon of water and you're good to go.

4) Repeat this process after each dump.


USAGE: Extreme Tank Cleaner

Use entire container to clean 1 tank.

1) Make sure to fill holding tank between 1/2 and 3/4 full.

2) We recommend driving for 45 minutes prior to emptying tank. The motion and aggitation of driving is what helps this product work so well. If you are stationary and can NOT drive, then we recommend filling tank and adding the Extreme Cleaner and keeping it in your tank 24 hours.

3) Do not leave Extreme Cleaner in your tank longer than 4 days.

4) *This only needs to be done maybe once per year. Please note: This product is guaranteed to thoroughly clean your tank. If buildup or sludge was preventing your sensors from working this product will get them working again. Sensors are notoriously finicky. We recommend paying attention to what comes out of your tank. If a lot of gunk comes out but your sensors still are not working - there may be an issue with your sensors.

    We bought a used 2008 Diesel Pusher. Despite flushing and treating the black tank several times, there was a slight smell that we couldn't shake. Extreme tank cleaner was recommended on a Facebook Forum, so we gave it a try. We were exceptionally happy with the results, and NO MORE SMELLS. Happy Wife...Happy Camper! :-)

    As the 2nd owner of this 5th wheel, I never thought about the original owners not using the black water holding tank properly. While my camper was getting some TLC and refurbishing at a repair shop, I was informed my black water holding tank was full of solids....I was horrified, embarrassed and ashamed. Although I was not leaving the black water valve open, it occurred to me that maybe the previous owners were not aware of which valve was which. My dad informed me of this product, granted I've used it 2 times on 2 different moves from state to state, there is a major difference in water color when rinsing the tank, it's actually clear water today. I recommend this product to anyone who buys a used camper just to be safe. You never know what the previous owners did or didn't do.
