The best baby oil for vector 3 pedals

There is a lot of discussion of the oil required to make the vector 3 pedals work, but I think it would be better to have some specific product recommendations.

I don’t have a baby, but if required I can get a bottle of the magic fluid. However, I suppose there must be something better than that.

For example, with my Lupine bike light I got this tiny tube of white, grease like paste that should be used for ensuring a perfect contact in cable connections. I believe it is something called Dutch grease. Can it be used for preventing the fretting of the vector batteries?
