It's global warming people and we're all supposed to wash our clothes at 30 degrees now, not 40 or 60.
But do you do it?
I only started recently, and I was quite surprised to ind that the clothes still got clean. My neighbor admitted to over filling the machine and boiling everything and it just made me feel that I had to do my part ;)
I do still wash mine and DHs bed linen at 60 as he has dust mite allergies.
