The problem is usually in humid climates where the dis-similar metals have a chemical reaction and corrosion forms at the junctions. There are a number of things you can do though. Several companies sell products that you can use to clean the contact areas and some act like a barrier to further corrosion. A simple fix that usually works is to "exercise" them occasionally. Just plug them in and out a few times. I do this about every 6 months with my stuff....at least the stuff that doesn't get swapped out all the time.
