I used to work in "hard surface care" (glass cleaners & such)... here's a trick you can try: take some dryer sheets (unused) and wipe your cables with them.
Not only will they smell "spring fresh" but some of the surfactant will rub off on your cable & that surfactant "scavenges" moisture from the air.
