Cornelius keg beer storage

[bez]

I did! Mine was a recon one from brewkegtap and my first brew came out with an unmistakable metallic twang...maybe it was this carbonic acid thing but my 2nd brew has come out much better....when i received the keg i rinsed out and sanitized but it did make me wonder whether i should have done something else to prep (ive seen some people talk about degreasing kegs but not sure if that applies only to new ones)

That is where I bought mine from
