After cleaning them use some petroleum jelly (Vaseline) to coat both surfaces before reconnecting.
I prefer dielectric grease over petroleum jelly. Dielectric grease conducts electricity while reducing corrosion. Petroleum grease, including jelly, can act as a low grade insulator unless the wiring connection is very tight.
Here's a discussion on dielectric grease versus petroleum jelly. It's worth noting the author mentions petroleum jelly is flammable while the silicone in dielectric grease is resistant to igniting. (Think about the silicone handles on oven bakeware.)
