6. Hillbilly Washer
This is a great method for off-the-grid low-tech clothes washing or, in my case, diaper washing as part of the Second Annual Flats and Handwashing Challenge.
The total cost to make this washer was around $6, and about 10 minutes. The amount of time it takes to operate depends entirely on the quantity of clothing and the type of material being washed. Denim, for example, will take more effort than t-shirts.
