Buying new, clean and fresh food grade 5 gal. buckets for food storage can be pricey.I've found some deli's that are saving me some nice heavy duty pickle buckets. It can take a long time to get rid of the odor.I have grains and beans i want to get into storage soon. I've cleaned them a few times with bleach and soap and they still smell.My question, if food is stored in heavier 7mm mylar bags,then stored in these buckets, will the odor penetrate the mylar and affect the foods flavor..? thanks..kevin
