I have access to a large supply of these buckets and they seem like they would be a great fermenter - they are about 10 gallons and the plastic is VERY thick (like 1/2"). The only thing is that they were used to store chlorine crystals used for water treatment. They smell like chlorine. Is there a suggested way of getting rid of the smell? I am afraid of using them for beer until I can get rid of the smell.
