Ok to use hazardous chemical container for composting?
I have a 55 gal drum that was at one time filled with Oil of Wintergreen. I bought it from craigslist to use for composting. I didn't realize this at the time, but apparently oil of wintergreen is extremely toxic. I'm wondering now if I should try to clean it thoroughly (and how) or if I should just give up and pay the dump to take it?
Has anyone done anything like this before? I bought some Simple green and rinsed that through the container, but I'm not sure if that is enough. I have a family and want to make sure this is absolutely safe to use.
Thanks in advance for any help
