I've obtained a dip tube that is stainless steel, but the nut portion of the compression fitting has a nasty black coating. It is labeled Parker 316 TW. I tried scrubbing off a bit of the black stuff and saw some shinier metal underneath, but I'm not sure I could clean the whole thing since it's seemingly permanently attached to the dip tube.
The black stuff rubs off on my fingers and is difficult to remove, so I'm concerned about putting it in contact with my beer.
Anybody know what the black crud is and/or how to remove it?
