Christ on a bike, the wife would put everything on a boil wash if she could.
My kneejerk reaction is this is just advertorial bolleaux to sell expensive detergent and more energy could be saved elsewhere in the laundry cycle. Our fabrics need the 40 and 60 washes, so does the machine to keep clean and the 30 wash prog on the machine is too gentle.
What’s the consensus from the resident energy-hadists?
