We use a wheelie bin liner to avid the problem of cleaning although there is a man who comes round and cleans them for a fee.
Annie, I agree they are better than black bag lying around. It's the number of bins for various things that annoy me. Both my daughters (one in Liverpool and the other in Poole in Dorset) have one wheelie bin for rubbish, one for recycling and a garden waste bin. We have one wheelie bin for rubbish, one for garden waste. then one box for paper another box for tins and glass, a blue bag for cardboard (and if it doesn't fit in they won't take it) and an orange net bag for plastics. Then there's the small plastic bags for batteries and light bulbs. The council are also talking about introducing bins for food waste.
