I have always just used isopropyl alcohol on Q-tips and gently rubbed the surfaces of the conductive rubber pads, and always had excellent results. I don't think that the conductive rubber loses its conductivity, but rather that the contacting surface of the rubber picks up dirt and pollutants and forms a non-conductive film that the alcohol (and very mild abrasion of the cotton Q-tip) removes.
