Know this subject has been done to death but since being furloughed have a bit more time to consider the thorny issue of washing clothes. Plus doing much more washing 
How do you sort items for washing and do you throw different iteMs in together or separate? What temperature?
I hate only putting on half loads (plus don't have that function) so like to put things in together to fill machine up.
So here goes (bracing myself for a flaming!)
Any combination of kitchen cloths/Bedding/towels/pants/socks at 60
Colours (non-pants/socks) at 30 (on coloured wash)
Darks (non- underwear) at 40 - often contains DH's stinky T-shirt's
Sweaters at 30
What does everyone else do to ensure the bloody machine isn't on all day, every day?!
