Currently I drypail, lid on. Wet pail would be easier than rinsing, though... So do I just half fill the nappy bucket with water, then? I don't add anything to the water? (I've read about putting bicarb soda and vinegar in when you wet pail - from my limited science, bicarb is alkaline, so would neutralize some of the acid, I think. But vinegar is acidic, so it doesn't make sense to me to add more acid!)

MadB, what about the smell when you leave the lid off?
