How many of you use the GEO method to clean your holding tanks? If you do, what is your recipe?

rskrbina · 09-27-2017, 01:07 PM

I use 1 cup of Calgon and 1 cup of dawn dish washing soap or laundry detergent.

In addition, do you put this mixture in the black and gray tanks through toilet, shower and sinks?

Duh! Just wasn't thinking

However you want to spend money is none of my business, however, I've used only water for several decades without holding tank problems, and it is cheap.

At home after a trip I fill my two black and two grey tanks completely, let them soak a day or so and then drain them.

I then add one cup Dawn and about two gallons of water to each black tank. Maybe a gallon of mixed Dawn and water to the grey tanks.

That stays in there while it is sitting, waiting for the next trip. I keep both toilets half filled so the seals don't dry out. Two toilets 13 years and still all original seals with no leak down.

I have been wanting to try it, but have had no luck finding the Calgon water softener. I recently returned from a 4200 mile month long loop from Louisiana to Yellowstone and back going through parts of 9 state, I checked for it at every time we stopped to resupply at various grocery stores and Wal-Mart's and never found the stuff.

For our next trip out, I will be adding 1 cup of granular TSP and then filling the black and grey water tanks to about 2/3 full. TSP makes water wetter and should help clean out each tank. When I get to the campground, I will dump them. Will be interesting.

Just started doing it last month and it works great. I found it at Wal-Mart after searching for about 15 minutes it was on a shelf with a bunch of odd ball stuff by fabric softener. Also available on Amazon

Two cups of Pine-sol, and on occasion a bit of Calgon.

SailorSam · 09-28-2017, 09:31 AM

Liquid Calgon (I think it's the same chemical as dry, but no one carries dry anymore) 2 caps plus 2 Calgon caps of Dawn. I use the Calgon cap as a measuring device. Any extra drains back into the bottle and I don't care if I get a bit of Dawn into the Calgon.

1 cap of Calgon into the grey tank every so often, not a as worried about that because there is already a lot of soap going there.

I wash our dishes (with Dawn) in a pan in the kitchen sink and dump the soapy water down the toilet when done. Then, I put about a cup of Calgon down the toilet into the empty black tank about once a month. Works for me.

we are pretty basic... each time we dump the black tank, we add a 1/2 of laundry soap, and a 1/2 cup of oxyclean.... we add back 4 toilets full of water... on our trip home we always dump 200 miles or so from home, and than dump a second time 25 miles out of town...

we full time 4 months a year... and have been using the same procedure for years..

we only use the above soap and oxyclean on the grey tanks on the way home to put the unit away....
