I picked up 2 55 gal food safe drums. (they had olives in them) How do I need to clean these out? I have them full of water right now and put 1.5 gal of vinegar in each also. But I can still feel the oil from the olives. How can I get this out? Some one told me to wash them with Dawn and just rinse very good and let water sit in them for a few days after. What should I do? I am going to use them for fresh water and salt water.
Thank you
