My cans have gone smelly because there is grey water standing around in them.   I tried washing them out with w/up liquid and a cloth, but it hasn't really worked.
Any ideas what to use, that will be safe in the garden ?  Thanks, Mrs Bouquet

Citrox is a natural disinfectant harmless to plants, which you can clean the watering cans with. Adding some to the grey water, might also help with keeping the smell down.
