often when our wheelie bin has been emptied, some rather foul-smelling liquid appears at the bottom inside. Is this put there by the binmen and, if so, for what reason?
Then you'll have some rather foul-smelling wet newspapers at the bottom of your bin! Have a flip-top bin with a bin liner bag inside it in your kitchen for all your rubbish. When the bag's full, remove it and tie the top closed. Fit a new bin liner in the flip-top bin and put the full bag in your wheelie bin. Make sure the wheelie bin lid is always closed, and keeps rain out.
