Thanks for that! There's 4 of us and a never ending mountain of laundry, but I like the soapnuts and feel all virtuous and smug that I actually made some household cleaner with it and put it in a spraybottle (as well as doing the laundry).
They are nuts that grow on trees in India / Nepal and its the shells that have a natural soap effect when wet. Have a look at the website I quoted earlier for a better description. You can use them in your laundry instead of normal washing powder and its much cheaper and better for the environment. Though a separate stain remover is sometimes needed. We keep meaning to make up a solution but haven't got around to it. It's meant to be a great shampoo too
