iz2sick, you beat me to the punch. I did, essentially the same thing. I used Q-Tips (cotton buds) with ispropyl alcohol and got some gunk out of there as well. That spinning connector is a total waste and failure point. Why it's even there is beyond me. In terms of "helping" you install or remove a tank, it's about as handy as a screen door on a submarine.
The trick is to get that oil and machining residue out of there so the connectivity to the 510 connector remains stable. I got really frustrated by readings that went over three ohms on a, nominal, 2.1 ohm 30s. It also made me worry about the possibility of overpowering the 30s when the resistance drops as the current hits and improves the connectivity. To me, it looks like an easy way to blow a coil.
I haven't had any buzzing other than the standard rattlesnake with the coils once in a while. I suspect that it's a loose board or loose component on the board, probably a coil used in the boost circuit since that would have enough mass to transmit the buzz pretty nicely. I sure hope that both of these problems get addressed by innokin because I'm buying two more VTRs, one for my wife and one for a good friend, as Christmas presents.
