If it’s a cable or wire that is mounted in something and not easily removed (replacement not an option) and you want it to not be sticky. Remove all residue with lighter fluid, if it’s a case of the plastic or rubber coating degrading and is the cause of the stickiness. Give it a rub down with wipe-on-polyurethane. It will seal it and provide a protective coating to slow or stop the degrading.


But for the most part just wiping it down with the lighter fluid should work.
