Just found out my new washer has a temp button which can reduce the temp of the wash programme right down to 25 degrees if you want and it also reduces the time of the wash cycle too . Question is do the clothes still get clean at a 30 degree wash? Not brave enough to try a 25 degree one. I normally use either Ecover or Tesco naturally liquid or the bio powder for the whites/nappies. Quite chuffed I found this out (even though I've had the washer for 2 months) as I'm on a bot of an energy saving crusade after some horrendous leccy bills over winter.
