I clean all my atttys pretty thoroughly with soap and a SoniCare toothbrush (got an UltraSonic cleaner recently, going to start using it), so I don't know if there would have been a machine oil taste. I had a little dust or dirt on the metal tank, but nothing major that I could eye on anything (those metal tanks were probably machined a few month a ago, huh...lol)
A buddy of mine (you know who you are, Oscar The Grouchin' it) didn't even clean it at all, got right to the vaping with no complaints [emoji14]
