What's the best Rubik's cube lubricant?
I've got myself a sticky cube, and I would like to make the twisting and solving a little more smooth for better times and less frustration. I'm cheap and some what attatched to mine, (and it may be useful for future projects) so I would like to revive it's full capabilities. I know petroleum jelly is initially effective, but ultimately eats away at the plastic. Does WD-40 work? Or just make the stickers come off? I know there are a good amount of cubers in the community, so I would like to hear the opinion of experience in order to make my cube's movement smooth and slick.
