How do I lubricate my Rubik's Cube?

From CubeOosan

First you will need some silicone spray, DO NOT use and oil based lubricant. Take your cube apart(do a quarter turn and pry the edge bit out) and spray all the cubes then put it back together.

Once the lubricant starts to wear off, you can just pop the edge peice up, and spray a little lubricant into the gap.
