Here is a link to a Facebook photo album detailing my experience using the non-electric Wonder Wash for the first time. It was relatively quick and easy, and I was able to use only 5 gallons of water, all of which I recaptured to use as gray water for flushing toilets.
As you’ll see, I did use the spin cycle of the regular washing machine for about 10 minutes, so I could hang my shirts without distorting them from the weight of the water. (I guess that would be the only water I couldn’t reclaim as gray water.) The only downside to the experience was that the directions that came with the Wonder Wash were unclear and incomplete. I had to go online to find instructions regarding amounts and temperatures of water to use for washing and rinsing, and then had to convert the liters to gallons. Not really a big deal, and it’s easy to remember going forward.
A friend wondered about whether soap would be left in the clothes at the end of washing. My clothes are still damp as I write this, so I will post again to let you know how they turned out when dry.
