worn compressor rings, not a real issue, I assume it is more of a build up over time, say a gram of oil is blown into the lines every year, well one gram would not be noticed nor two but since it soes not evaporate it builds up to the point that you can see it, some oil is blown by brand new compressors and over time gets to be more and more, but as long as you are still getting full pressure you do not have to service the compressor, but since this is being used on water pipes I would install a trap inline to catch the oil

I would recommend soap (Dawn) and water. Then blow the air line out to dry them. I would not recommend a flamable solvent. You can make a water eductor using a tee and a small plastic tube and some fittings from the local hardware. you attach it at the compressor outlet and put the tube into a bucket of soap water. As you blow air through you hose you will **** up soap water and send it down the hose and out with the air. That should do it.

It is normal for these units to pass osme oil. If you have had the machine awhile, and think that the problem has gotten worse, start by changing the oil separator filter (inside the oil tank). Also check the scavenge line that dips to the bolltom of the serparator it must be unblocked. There may be a nozzle and/or strainer in the scavenge line as well. Make sure they are clear.
