This is a food grade barrel. I know these to be used for pickled foods and
olives are common to have been shipped in these.
We're going to re-purpose this barrel into a rain barrel. You want to make
sure you scrub both inside and outside thoroughly. Since food was used in
this at one time. We don't want that mixed in with our rain water.
I used a old sponge and Mrs. Meyers all purpose cleaner. I let em soak for a
while. Fill it a quarter of the way up with water and a 2 cups of cleaner.
