I do my own:
Pour thin bleach around the sides, follow up after 5 minutes with kettle full of boiling water.
Run a bowl of hot water and empty into wheelie bin with some washing up liquid.
Take wheelie bin for a short walk thus stirring everything up.
Empty into drain.
Hose down wheelie bin and empty again.
Leave lid open to dry.
Job done.
But I am a tight *******.
This works a treat
