My DP's mum has told DP that we should be washing all of our clothes at 20 degrees as that's what she does and that it's better for the clothes (no idea why). I pretty much wash everything at 40 degrees, apart from towels and sheets which I was at 60 degrees.
He's been putting washing on at 20 degrees, including sports clothes. The sports clothes don't smell clean when they come out, they still have a slight odour of sweat. Surely this concept of washing e everything cold is a bit unhygienic as it doesn't clean the clothes properly?
Does anyone else think this is not the way clothes should be washed or is this something most people do?
