Here is what the GEO Method is.
The GEO method ingredients
The GEO method is a home-made cleaning technique thatís been around in the RV community since (at least) the early 80ís. Where the name came from no-body seems to know, but the original method is HERE
. The original formula uses chlorine, but that can ruin your valves so these days most RVers use a slightly modified method with just 2 common items, both of which you can get at any big department store:
- Calgon Water Softener -> This stuff helps to break down water surface tension, clean scum and prevent hard mineral deposits. Iíve used Borax on occasion when I canít find Calgon and find it works just as well.
- Dawn Dishwasher Detergent -> The ďoriginal formulaĒ blue detergent is excellent at cutting grime. Laundry detergent works too.
After you dump pour 1 cup of Calgon and 1 cup detergent into the tanks. Leave them in until your next dump. Before driving some RVers will also throw a bag of ice-cubes down the tank to ďscourĒ their walls (weíve never done this, but others swear by it).
And thatís really it! We donít use the GEO method each time we dump, but just whenever our sensors need an extra cleaning. Either way itís a simple, easy and environmentally-friendly method to keep sensors mostly
clean. And in a moving house on wheels thatís really as good as it gets.
