The rings went bad on my reciprocating air compressor and when I drained it I got some milky tan oil/water mixture. I'm in the process of rebuilding the pump but I was planning to do some painting soon and I'm worried about the oil getting on the car. I'm aware of the various oil/moisture filters available but is there anything else I can do to remove the contamination that must be throughout my air lines?

My air system is properly plumbed to include drip legs for crud to collect in. From the tank the line goes into a 6' long, vertical, 1" black iron drip leg with a drain at the bottom. Then 1/2" black iron lines go horizontally from the top of this drip leg and at each drop the line comes up 10" from the horizontal line before turning down to the the air outlet. All lines continue past the last drop and are pitched to a drip leg at the ends with a drain at the bottom of the leg. I have had some of the oil/water sludge come out of the drip legs at the end of the runs so I'm pretty sure it's throughout the lines. I'm just not comfortable risking a paint job "hoping" the oil has been blown out. I need a way to flush the lines and tank. It's a 60 gallon tank so "sloshing" something around inside isn't going to work.
