I can’t be bothered with all that and just wash everything at 30c on the quickest setting. Though I do also have to do an extra 1400rpm spin cycle to get rid if the excess dampness as my machine only does max 1000rpm at lower temps.
My main washing gauntlet is my drying regimen as I tend to max out the radiator. I hate slow dried clothes if they are not dried outside, as thicker shirts and trousers and the elasticated parts of boxers and thick socks get a nasty damp smell if no radiator is involved (shitty northern europe weather).
