There are conductive greases specifically designed for this purpose. As Grunff says, any grease will do ( I've used Vaseline ), but I've since switched over to Holt's battery grease. Clean the terminals well ( you can rinse them off with water or a water and baking soda solution if you want to get fancy), and apply the grease liberally.
