What's the difference between washing clothes in a washing machine and Filling the tub with water, clothes and powder. Soak it for an hour or so. Drain then repeat again. Or other lazy, non mechanical process? If so what process? Assuming clothes that aren't too dirty and with no special treatment like delicate material or colours or anything. With the method I described, if I used hot water compared to only using cold water in a washing machine, would it turn out better then the washing machine?
