the bucket lid, doesnt completely seal like the rubber ones, it has little flaps thatclick down IYKWIM? which is why i bought it.
but yeh that smack u in the face ammonia smell is there!! i wash my nappies every second day so its not as if theres sitting in there for ages.
J i would put it outside but i think the dog might find it a little too interesting!!!

my give it a wash with warm water and see how that goes
