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.

    Bought the Extreme cleaner for our grey tank because it worked 'extremely well' in our black tank.

    I purchased this to get my sensors in the black holding tank to work but it didn't help. However the water that came out was brown whereas it had been clear prior to using this product so evidently it did clean the tank but not affect the sensors

    We have tried every product you can think of to clean holding tanks and we have been trying for 20 years EXTREME is hands down is the best product we have found and I guess that's why it's been hard to get

    Absolutely positively the best tank cleaner ever made. After many other attempts to clean and deodorize my black tank HappY Campers Extreme did it in one try. I am now following up with with regular Happy Campers and have not had a single issue. My sensors actually work now too. I strongly urge you to use Extreme to get it cleaned right the first time.

    This is the second time I have used this product and I am very happy with it. Since I likely let too much "material" build up during the camping season, it is nice to have this product at the beginning and end of the season to do a thorough cleaning. Having a clean tank allows the Happy Camper treatment that they sell to do a great job keeping things clean. I like to use this product once a year to keep my black tank working well.

    I was dealing with a possible huge headache with my black tank as well as the usual issue of tank sensor problems. I used the Happy Campers Extreme product and then the regular Happy Campers. The black tank now runs clear and the sensors work! Thank you for a tremendous product!
