First timer here. Hi everybody. 
I bought a lot of 10 corny kegs off of craigslist a few weeks ago. Of the 10, 2 had a smaller diameter opening on gas dip tube side. In order to replace the plastic dip tubes with the larger diameter stainless steel ones, I had to drill out the excess metal.
My question is, how do I ensure myself I've gotten all the metal flakes washed out of the keg before I attempt to serve beer out of it?
