Re: Clothes washing..
Dirty wash twice a week, that's all the dog stuff and my husbands muddy dog walking towels.
Uniforms twice a week or daily in summer.
Bedclothes once a week.
All other clothes weekly.
Various temperatures and times and yes tumble dryer is popular, if it doesn't go in there it has to hang around the flat and that causes damp.
I've got one skirt has to be washed alone as dye comes out at such a rate it makes everything purple ! I've set it many times still oozes purple.
