What echo freindly cleaner can I use to clean the tanks of an RV?

Simple Green cleaner.

I use bleach.

anything for septic tanks will work(Green GobblerModel # GGSSEPSeptic Saver Enzyme Pacs)

here are some ways to clean black water tank----- Ice Cubes and Detergent: The ice cube theory is one that’s been sloshing around for many years. Some folks simply add 2 to 3 bags of ice cubes into their RV tank and go for a drive. Many swear by this. As an added bonus, the theory has been expanded to include adding a quarter cup of dishwashing detergent (NON-antibacterial version) plus 2 gallons of water to the tank along with the ice cubes.

Dawn Ultra or Joy seem to get the highest hits for the type detergent to use. RVers then simply take a drive for 2 to 4 hours, like take one of your excursions for the day, then return to your site and dump and flush repeatedly. It’s easiest to ensure you do this at a location where you have full hookups.

Add about 3 gallons of water to the toilet when done and the toilet treatment you normally use, take another drive around to mix things thoroughly and then flush the tank once again.

This method may work best with a motorhome since driving around is involved or do it on a day you are relocating your fifth wheel or travel trailer to a new location. Also, ensure you do not overdo it with detergent or your RV may be foaming all over the place. This method is used occasionally as a thorough cleaning; it’s not necessary each time you empty the tank, of course.

Yeast and Peroxide Flush: To get rid of solids and odor in the black tank, try using some yeast and peroxide. It’s a tried method and an inexpensive one at that. Add 1 gallon of water to an empty black tank, 4 oz. of yeast and 10 oz. of peroxide.

Take a drive, perhaps to your next camping location, while the water/yeast/peroxide splashes throughout your black tank. Empty the tank and refill with some water and your normal black tank treatment additive. This method has been reported to eliminate solids and odor, but not paper.

Calgon, take “it” away: Another theory that seems to be worth a try is adding a water softener, such as Calgon, to your black and gray water tanks. This is known as the GEO method(GetEverythingOut) In any event, many RVers have tried this method with much success.

Once your tank is empty and valve is closed, mix 2 cups water softener with 1 to 2 gallons of hot water for each tank. Pour into your sink or shower for the gray tank and into your toilet for the black tank. The premise is the water softener keeps any gunk from sticking to the insides of your tank and to the sensors. This should allow the tank sensors to stay squeaky clean, thereby eliminating any crud or slime hanging onto them and causing inaccurate monitor readings.

It is also acceptable to add 1 cup of the original “blue” Dawn dishwashing detergent or 1 cup of eco-friendly laundry detergent to the black tank when you add the hot water and water softener. This helps to further clean and deodorize the tank. As an added measure, many RVers include ¼ cup Borax to the black tank along with the detergent. Borax serves as an excellent cleaning agent.

No driving around this time. Simply use your tanks as you normally do and empty when the tanks are 2/3 to full. All these products are safe and eco-friendly. The GEO method can be used on an “as needed” basis or each time you dump the black water tank.

Put ice cubes --several bags, vinegar and soda --this is a natural way and then go for a ride with your RV, fifty wheel, or trailer. It will slosh around and clean the nooks and crannies.

Simple green is non toxic to humans, animals, and the environment. You can get it in spray or concentrate in home improvement or just concentrate in Walmart. It disinfects and deodorizes. I use it for all my cleaning inside or outside. We love it!
