Here is a question from Mr Hippipotami (should that be hippipotheis?) about using soapnuts in the washing machine:
During the rinse cycle, how do you stop soapnuts from releasing 'soap' so clothes can be rinsed clean?
I have explained to him that the residue of soap is so small, it does not need to be rinsed off, and he replied : 'good thing too as with the soapnuts in the drum the rinse cycle is next to useless!'
That is true though isn't it - the soapnuts don't leave a residue like detergents which needs to be rinsed off?
