WD-40 is not a lubricant, even though many people use it as such. It's a water displacement product. The name "WD-40" refers to water displacement formula number 40.
This is the ideal product to use since it specifically made for the purpose:

I bought mine at Camping World a few years back. One can will last a long long time.
Here's a little more information about WD-40:
In 1953, a fledgling company called Rocket Chemical Company and its staff of three set out to create a line of rust-prevention solvents and degreasers for use in the aerospace industry. Working in a small lab in San Diego, California, it took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40® -which stands for Water Displacement perfected on the 40th try—is still in use today.
