Clean the roller surface with a dry non-metallic kitchen
scrubbie, wipe clean with a dust-free soft cloth, then
find some molybdenum or at least the "DuPont Performance"
(moly and teflon) treat the roller and contact surfaces
with it.
The "moly" lubricates without attracting and holding
dust and other small abrasive, insulating, and/or acidic
debris -- unlike most lubricants.
And yes, it generally is more expensive! :-)
I am guessing that your roller *may* be silver coated;
someone else here would have to address the nature of
a cleaning substance specific to a silver coated
surface that will not harm conductivity or attack the
roller core.
BTW: Does your roller have a ceramic form or is it
nothing-but-air, as the "March Madness" hoop fanatics
would put it, under the coil?
