Our washing machine is a water-efficient front loader and it only uses the right amount of water for the load size. So I was really surprised at just how much difference daily washing made. We have a water tank which we use for all outside watering so I don't need to use the grey water either. I will keep going the way I am now with bigger loads less frequently and hope that I can keep on top of it all. The worst thing is when I am hanging out a load to dry at 10pm at night after work and I wish it was a smaller load!
