Contamination is the leaching of the carbon black of the outer
insulation into the center insulation, causing it to become lossy.
I've never seen what you describe, but just as a guess it might be
plasticiser (solvent?) "condensing out" of the center and outer
materials. The same greasy stuff that clouds up the windshield of
automobiles and is almost impossible to clean off!

Folks,
I have encountered a strange issue here in the shack. I have a spool
of coax which has been with me for 20 odd years. When I went to make
jumpers, I find that the copper shield is kind of sticky. It would
seam that the outer shield has "leached" into the inside of the
coax. Is this coax any good? I don't think the coax was exposed to
weather, other then storage in an unheated garage. Is this normal?
Is this what is called contamination, as in non-contaminating coax?
Thanks for the off topic bandwidth.
73,
Ron
