How to clean a keg after plasma cutting?

[Scout]

I thought it would be easy to just cut the top off a snake to use as a fermenter, but after plasma cutting I'm left with this residue inside. I've scrubbed it with a rag and soapy water, and its somewhat clean. Is there something I can do or use to make it fully clean?

I don’t know if it will work for you, I’d try Barkeepers Friend. That stuff is a great cleaner for things like that.

Yup, BKF and a stiff scrubby would be my first shot as well...

Cheers!

BKF FTW

How will you seal that gaping hole?

I have a glass lid with a silicone seal around it. I will make a clamp to hold it down. I wanted a large hole so I could get in and clean it.

How will you seal that gaping hole?
