So I bought two 15g food grade storage barrels. They were previously used for soda. 20 bucks for both, couldn't pass it up just in case I could use them. theres a small opening on them, not big enough to get a hand in to scrub out real good. so Ive rinsed them multiple times, used vinegar to try and rinse them out. they still smell like soda.
Is there anything else I can use to clean them out? and will the soda syrup be harmful to the tank if there is any leftover in the container?
