Black wheelie bin has got a bit whiffy. Nothing horrific like maggots in there. Do I just scrub it with a bloom and hot bleach or is there a mumsnet trick I'm missing that will get it smelling nice again with a bit less effort? Also I'll have DC in the garden with me so whilst I can keep them away from the bleach if I can get the same job done with fairy liquid or something less toxic I could rope them in to help
