Well, I just bought ten 5 gallon buckets that had pickles in them. If you don't know... the smell of pickles is pretty strong. In the past I just used Baking Soda to get the smell out (it worked). Even though it worked I was wondering what you use (hopefully it is better). The woman I got them from said they use bleach to get the smell out (the good thing about using bleach is that it will be free of microbes (for the most part).
