I found laundry in the machine this morning from yesterday (or Saturday?!) I honestly don't remember when I put it in. It smells a bit damp but not overly so, but then DH always seems to smell it more.
Sometimes pegging out slightly damp smelling washing gets rid of the smell but I think I'm kidding myself today.
Also sometimes washing doesn't get rid of the smell?!
I'm sure Mumsnet has the answers!
