This may have been left in a wet spot and the cable sucked moisture like a straw wicks water.

I have seen under-floor cabling draw moisture from wet ducts.

Yes, the moisture would feel oily as it is picking up the leftovers from the sheath and cable insulation.

If this were Cat 5 the moisture will upset your certification equipment. The trapped water acts as a mirror and reflects the signals.

Just my hair brained experience.....
