I use bleach for a real stinky bucket. Of course I have to be sure to get all the bleach out, and for me (uneducated opinion) a hot oxyclean soak and good rinse gets rid of the bleach. Others might say hot oxyclean soak overnight, or whatever. I am sure there are other ways to do it, but thats what I do.
