Second Use For Everything (SUFE)
Chris Goodall in his book “How to live a low-carbon life” page 117 talks about Washing Machines being cold-fill. That is, washing machines with only a Cold-Water Inlet; no provision for Hot Water Input.
I soak my laundry in 25-litre pails the day before laundry. I add a dash of detergent to the water and let time do the work.
