Ok, I shot a video of this last night, so if you watch the video you can see a good example of what I am talking about. Start watching at about 2:20 to about 3:00 if you do not want to hear me babble.
I have a SS keg that I have cut open, installed a sight glass and spigot. Once I cleaned up the inside I saw what appeared to be dirt/rust. It does not appear to be pitted as the material in question seems to be above the surface.
I do not know how to get rid of it and I am coming here for suggestions. I have tried Bar keepers friend, and it is still there. I have purchased Phosphoric Acid, but want to inquire here before I go and do something stupid.
Can anyone provide some step-by-step help in this matter? Also if I am able to get it off, is there a way to "cure" it again so it doesn't happen again or at least the metal is protected again?
Thank you in advance, the video link is below:
