We have now got these wheelie bins and our dustmen only collect fortnightly..well one week the green bin and then the following week the grey bin.The green one is O.K because it is mostly paper and plastic, which has been washed, but the other one does hum a bit in the hot weather.We have no cleaning franchise in our area so I stick a drop of bleach in the bottom after they have emptied it and hose it out. Luckily we have a garden hose and an outside tap.But they are big and cumbersome to clean.I sprinkle dustbin powder in it from time to to time as it is in use...All a pain in the butt really but I suppose we have to do our bit for the environment!
