I wash at 60 if I possibly can, they come out cleaner and I do not have to use biological or souped up (with extra chemicals) detergents. I use a French soap based detergent that does not bring me, or my DDiL up in a rash.
I think whatever energy is used up heating the water to 60 is balanced by all the extra chemicals and processing needed to get washing hygienically clean at those low temperatures.
I hope this celebrity isn’t who I think it is………
