Cleaning Barrels for Water Storage

[TheSaint216]

I got some Barrel's from buddy to use as RODI storage. These contained Malted Barley and Water for use at a Micro Brewery. How can I go about cleaning them out? First thought is just putting a small jug of Vinegar in it and rolling it around and rinsing it out. What do you guys recommend?

That would be fine or even a gallon jug of bleach with water or a 10% muriatic acid solution. I think any of the 3 and rinse well and you are set!

I cut the lid off mine, and climbed in to give it a vinegar and water scrub down. Then was good to go.
