dry pailer here! all the way.
i once tried soaking and added some php nappy soak, as per instructions. what a disaster. when i opened the bucket it smelled like perming lotion and had reacted in some way and gave my rainbow bots lovely lilac couloured stains. the smell was awful and the poop was sort of, half dissolved and slimy! eeewwww!
i am never doing that again needless to say.
i find no problem with drypailing. if they are particularly nasty i put them on a rinse first, thats all thats needed.
