I would use a very very slight amount of Vaseline. It is not a good idea to over-lube these actuators, as they will have a tendency to open while driving due to the vibrations of the trailer. I suggest you just clean them real well, and then leave them alone..a little friction will prevent the vents from opening while driving.
Frequent use will help keep them working well. They corrode when sitting unused for a long time.
