David Stockton is the author of this very original concept called Ecowash that represents an eco-friendly way of washing the dishes.
The device could be very useful when you go outdoors. This is because it is rather compact but most importantly because it does not require electricity.
All that you need to start using the device is a bucket of water and a cleaning liquid. You will also need to do some muscle work.
The whole process is very simple and can be done very quickly. Inside, on the rotating dish rack you can place up to 4 sets of plates. Then a crank needle is used to spin the rack.
A release window can be found at the bottom of the device. It allows the user to discharge used water. After washing the dishes and getting rid of water you can start the drying process with the help of centrifugal force.
